What are the different uses of granite?

The different ways in how granite can be used

Many civilizations throughout history, due to its beauty and abundance, have used granite for their constructions, such as columns, doors, vases, statues, and more granite works. Moving on from the past, in this blog, we will talk about the main uses of granite in the present. Nowadays, with the equipment we have at our disposal, its aesthetic characteristics, and its hardness and resistance, working with granite is very common.

One of the most important uses of granite is in architecture. Its low cost, its properties, and its appearance have made it the choice of many architects and artists. It is used for many works, from monuments to large constructions (such as water reservoirs), bridges, and pavements. A further use of granite is for indoor applications. Its durability and elegance are why it is one of the most popular materials for decorating homes and buildings. In this context, its applications are diverse, although we could say that it is the lord and master of bathrooms and kitchens.

The granite also has its role in funerary art. As we have already said, granite is a resistant and elegant material. Both these characteristics, added to the fact that granite is very resistant to acid rain, make it the perfect choice for elaborating tombstones, mausoleums, altars, etc.

To conclude, we will mention its relevance in the pulp and paper industry and how it is used in the field of aggregates. On the one hand, granite is the input material used to manufacture the paper pulp rolls used for grinding and draining water from the paper pulp. On the other hand, granite is also crushed to produce material for concrete, mortar, roads, rock fill, and railway gravel, among others.

 

That’s the end of today’s blog! If you have any questions or something you missed and want to share, we will read you in the comments.

Marcelino Group in Marmomac 2022

This is how our visit to the new edition of Marmomac went.

One more year, it took place the world’s most iconic natural stone fair: Marmomac. Therefore, Marcelino Group flew to Verona once again, where all companies in the stone sector come together to understand the evolution and observe the most up-to-date trends in their environment.

stand de Grupimar en Marmomac

Last year the fair presented a dual-modality, this one was no different. On the one hand, the classic on-site format that we all know, and on the other hand, Marmomac, the online version of Marmomac where companies have the opportunity to share their products all year round.

Marmomac PLUS is not just a granite, marble, and other natural stone products showcase, but also machinery and different technologies for stone, chemicals, and abrasives. In other words, Marmomac PLUS, opens up a virtual hub for companies that allows us to cover the entire value chain, the whole process from the quarry to the finished product.

In this edition, we have been able to see different and new designs, textures, shapes, and coatings. Although it is a very traditional industry, creativity and innovation are a pleasant surprise this year at Marmomac!

Every year, we travel to Verona with the illusion of seeing our friends in the sector at Marmomac where, in addition to presenting our products or expanding our customer portfolio, we have also considered that it is a great opportunity to see our buyers, building links and consolidate relationships with them.

One of the most remarkable details from this edition of Marmomac comes from one of those customers that we consider a good friend. Talking among ourselves, he recognizes that one of the main reasons for attending the fair in this edition was to be able to share a moment with us, a moment that, otherwise, would be very difficult, if not impossible, because we live in different countries.

Closing this blog on an emotional note, at Marmomac there is always a lot of stone, but we have melted it with a lot of smiles and the joy of getting back together after a couple of difficult years.

Quarries Restoration

Quarry restoration is the last stage in the process of exploiting the planet’s natural resources, which consists of rehabilitating the exploited areas in order to minimize the footprint on the environment.

There are very strict regulations on the effects generated by the extraction process (the composition of liquid discharges, dust emissions, noise or restructuring of the landscape…); for which you must have an environmental impact study and a waste management plan.

Our quarries, our commitment

One of our commitments is to take care of the environment; our quarries always comply with current environmental protection regulations. This assesses the effects generated in the environment and the corrective measures to be carried out to maintain the landscape and ecological values of the area. At the end of the operation, all the land is restored to its original appearance.

Quarry restoration process

Legislation in Spain

Since the Mining Law of 1973 and up to the present day, the operator of the site has been held liable if any damage is caused in the process.

In the years since 1973, further improvements have been made through legislation to protect the environment and economic development.

Broadly speaking, what has been implemented?

  • A Restructuring Plan must be submitted that guarantees and commits to the rehabilitation of the space used.
  • Obliges the restoration of the affected land
  • It regulates the deposit of guarantees in order to be able to face the restoration work.
  • It is essential to manage all the waste generated so that resources are not wasted.

At Marcelino Group, we promote the conservation of the natural environment, and we have established methodologies and systematics for the extraction and transformation of our granite.

What do you think? If you have any questions, we’ll read them in the comments. Check out our last post here.

The low carbon footprint of granite compared to other materials according to the EPD

In the past, construction materials were obtained naturally, from the environment itself and adapted to the conditions in which the project was carried out. However, as time went by, the demand increased, thus increasing the distance between the sourcing of raw materials and their final location. Today, the construction industry aims to use low environmental impact materials to reduce the carbon footprint. Glass and steel are materials with the highest environmental impact, however, granite is one of the most sustainable materials according to the EPD (Environmental Product Declaration).

Why is granite the most eco-friendly choice for the planet?

Since the 1970s, our granite comes from blocks that have been sawn with a diamond wire; it is a machine designed to produce slabs and tiles of variable thickness from granite blocks. In order to use this machine, it is essential to use water, the good news is that it is in a closed circuit so that it is not wasted. This technology stands out for its energy efficiency, as its effective consumption is lower compared to other methods.

Another important element: the rubble generated

All the tailings or rubble generated in the production of granite blocks are recycled and transformed into aggregates of different granulometry, which are then supplied to concrete plants, terrazzo factories, construction material warehouses, etc. for their full use.

Finally: granite in homes

Houses in which granite is used as the main material are more sustainable. This material offers better insulation than others (thus obtaining greater energy savings in housing resources). It should also be noted that it is one of the most resistant to weather changes (it is more durable over time), adapting to the urban or rural environment, unlike other materials such as wood or aluminium.

What did you think of the article? If you want to know more about granite and sustainability, don’t hesitate to ask us.

The granite to build your home

Sustainable housing using granite is increasingly valued for its qualities compared to conventional housing. The use of granite in its cladding is one of the most efficient options, both technically and aesthetically, as it has outstanding properties such as: durability, strength, easy maintenance, among many others.

Aesthetic richness of granite

From an aesthetic point of view, granite is one of the most outstanding materials when it comes to achieving a differential and elegant façade. At Marcelino Group we work with a wide variety of granites of different shades and textures, achieving the expected results.

Sustainability

From its production, the manufacture of granite involves reduced energy consumption compared to other types of materials. At Marcelino Group, in addition to the closed water circuits for cutting, all the waste or rubble generated from production is transformed into aggregates.

Aggregates

 

Durability

In the long term, granite has practically minimal wear and tear, and is resistant to all types of weather and temperature. According to the Mohs scale (used to determine the durability of various materials) its hardness is between 6 and 7.

Why choose granite for your home?

In addition to all its aesthetic qualities and the fact that it is highly durable, granite has surprising insulating properties, which will make your home more comfortable and energy efficient.

It is the perfect material to withstand the high summer temperatures and keep any home cool without the need for air conditioning, which translates into savings of both resources and money in the medium and long term. For all these reasons, choosing granite to build your home is a safe bet due to its versatility and sophistication.

If you are thinking of building your home with one of our granites, contact us, and we will advise you.

Decorative and modern granite staircases

Granite stairs are an aesthetically pleasing and resistant decorative element. As we have already mentioned in other blog articles, granite is a natural stone that has excellent qualities for its use in construction due to its high resistance, long durability, and easy maintenance. But, it is also a very versatile material that offers varied and elegant decorative possibilities.

Stairs have always played an important role in construction. On one hand, the functionality to communicate areas at different heights, but also, as a decorative and ornamental element, gives rise to increasingly original and modern decorative forms, which can be combined or contrasted with other construction elements such as walls or floors.

Advantages of using granite on stairs

If you are looking for a material that is always on trend and never goes out of fashion for stairs construction or cladding, then granite is your best choice. From classic and elegant designs to different styles adapted to the latest trends, the environment, or the constructive characteristics where it is located.

Granite staircases come in a wide variety of shapes, adaptable to any design you propose. From straight to curved staircases, including spiral ones. All of them with different finishes and shapes, depending on whether we are looking for a traditional, minimalist, modern, or sophisticated style.

Besides, you can also choose between different granite textures. Each of them brings a unique and personalized beauty.

Another decorative element that can be played with is the handrail. If the stairs are supported by banisters and handrails, the weight is divided and the centimetres of the steps can be smaller. However, if the stairs only consist of steps, they should have more centimetres.  

Granite stairs for outdoors and indoors

Due to its resistance and water insulation, granite is the preferred choice for outdoor stairs. Usually, the granite finishes chosen for outdoor stairs are flamed or shot-blasting, with some roughness to avoid slipping.

However, granite is increasingly used in architecture and has a growing presence in interior decoration.

Types of granites for facades

When we think about the types of granite for facades, what we really have to focus on is in the type of finish.

A well-designed facade is the letter of introduction of what we will find inside. Granite in facades, revalues the property in the market.

 

Types of granite finishes for facades

The recommended types of granite finishes for facades are:

  • Flamed granite: This is achieved with a blowtorch, applying 2800 °C on the surface of the stone, which produces a few chips and gives the surface a rough and crystalline appearance, as well as providing it with more resistance.
  • Shot-blasted granite: To achieve this result, metallic particles are projected which erode the stone, resulting in a rough, non-slip surface with a more natural appearance.
  • Bush-hammered granite: By carving the stone, that is, by hitting it with a hammer that generates craters in the stone between 1 and 3 mm deep, we achieve the rough appearance of this type of granite finish.

Another recommendation to take into account is that the thickness of the granite cladding should be greater than 3 cm.

Advantages of granite in facades

We know about the advantages of granite, its resistance, low porosity and its ability to withstand inclement weather, but granite is also the most abundant and resistant natural stone on the market.

Other advantages offered by the use of granite in facades are:

  • Personalization and personality: Your facade can become a quality decorative element without taking up much space, giving it elegance and architectural value.
  • Cost-benefit ratio: OK, the price of granite is slightly higher than other materials (really, just a little) but, considering that its maintenance is minimal and its durability infinite, it is more than worth it. Besides, you can always reuse it.
  • Revaluation: Did you know that granite increases the value of your home? Natural stone cladding increases the value of the property: luxury and quality stand out, but also its energy efficiency, resistance and durability: so, granite is sustainable.
  • Variety: We can find multiple colours of granite, this depends on the concentration of quartz, mica and feldspar present in the stone. But no natural stone is the same as any other, so your choice of granite will always be unique and original.

Remember!

  • Any granite can be used for facades, but not just any finish.
  • Granite is resistant to erosion and weathering, for a very low maintenance cost.
  • Granite adapts to any decorative style and never goes out of fashion.
  • In both very hot and very cold climates, granite is a thermal insulator, so if you are considering using granite for facades, you are betting on energy savings.

Granite: a safe bet for your renovation

As we pointed out in our article on trends in architecture and construction for 2022, many homeowners are considering different renovation actions in order to meet the great challenges of construction: comfort, habitability, accesibility and energy efficiency. In this article, we tell you why granite is a safe bet for your renovation plans.

Advantages of granite in renovation

Granite stands out for its high abrasion resistance and flexural strength, characteristics that make it ideal for withstanding sudden changes in temperature, as well as road and pedestrian traffic.  Since it is an impermeable rock, it is excellent for constructions in contact with water.

Its use is highly appreciated by builders in kitchen and bathroom countertops and floors, in tile format for interiors and exteriors and also in street furniture applications or as paving stones or kerbstones in transit areas: squares, pavements or building accesses.

Providing a home with better levels of energy efficiency is one of the main challenges of any refurbishment. Granite, thanks to its exceptional thermal insulation, protects the home from low temperatures and keeps the interior temperature more stable.

When a renovation is chosen instead of a new building, it is often due to a question of economic costs. Due to its durability, granite offers a magnificent quality-price ratio and also allows the initial investment to be amortized in a short period of time, as the house is revalued.

When it comes to renovation, another important criterion is to opt for materials that adapt well to any aesthetic decoration. The versatility of granite, thanks to its different finishes and chromatic variety, makes it possible to offer all kinds of elegant and long-lasting combinations. Also, if the original building was built in stone, we can take advantage of the existing structures, adding a little more material, which will allow great cost savings.

Finally, the choice of granite allows a better integration with the landscape, respecting the environment or the constructive characteristics of the area.

In summary, the most significant advantages of granite applied to renovations are due to its outstanding physical properties:

  • It increases the value of the property as it is a noble piece.
  • Easy maintenance and cleaning
  • Difficult to scratch and stain
  • High resistance
  • It has an eternal lifespan
  • Each piece has a unique beauty. No two pieces of granite are alike.
  • Allows tailored pieces to be made
  • Thermal insulation.
  • Excellent value for money compared to other materials with a much shorter lifespan.
  • Landscape integration.

If you are planning a renovation or rehabilitation, contact us, we will be happy to advise you.

Granite, elegance and durability in outdoor paving

The resistance, elegance, and durability of granite make it a perfect material for all types of exterior paving.

From an aesthetic point of view, granite is also a very versatile natural stone that allows the creation of the most diverse decorative styles.

Recommended granite finishes for exterior surfaces

When choosing which type of granite is the most suitable for exterior cladding, it is important to pay attention to the finishes. In addition to durability, it is essential that the surface is non-slip and resistant to the weather condition, such as sun, rain or low temperatures.

One of the most popular finishes for this type of surfaces is the flamed finish, which gives the surface a rough appearance without altering its colour. This type of finish is easy to maintain and prevents slipping in rain or humidity.

Other finishing options that perform excellently outdoors are sawn and bush-hammered. With the former, a flat surface with a certain roughness and fine texture is achieved. In bush-hammered, the treated surface presents small “craters” or irregularities 1 to 3 millimetres deep to achieve a rough appearance.

Wide range of colours to create warm and luminous atmospheres

In addition to the type of finish, the origin and colour of the granite are characteristics that also influence the durability and resistance of exterior surfaces.

Dark tones such as Azul Noche or Azul Plata offer excellent qualities of impermeability and resistance outdoors, as well as high anti-slip protection.

However, by applying the most suitable finish for each space, we can create all kinds of atmospheres in white, grey, cream, pink, green or black colours.

In our catalogue you will find the perfect inspiration for every atmosphere.

What does 2022 bring us in architecture and construction?

We are on the threshold of the year 2022 and it is a good time to take a brief look at some of the trends in architecture and construction that will mark the coming year.

 

More sustainable buildings

 

There is a growing concern for the preservation of the environment, which translates into a growing demand for more efficient buildings and transformation processes that are more committed to sustainable development.  Saving resources, replacing the most energy-consuming processes with more efficient ones and reducing the environmental footprint are the challenges we face and a priority objective at Marcelino Group.

 

Refurbishment and renovation

 

Related to the previous point, old buildings have shown their great deficiencies in terms of energy efficiency, comfort and accessibility. This implies the need for many owners to adapt their properties to current requirements and needs.

Among other actions, it will be necessary to opt for materials that help to improve thermal insulation and contribute to better energy efficiency, as well as the integration of renewable energies in the home.

But new construction is not lagging behind and it is increasingly important to build to the most demanding standards of the Technical Building Code or Passivhaus.

 

Brighter, more functional and better insulated homes

 

Mobility restrictions due to the Covid-19 pandemic have changed the concept of housing. With remote working and spending more time at home, larger and more functional spaces are sought after. Also, while the open concept has been on the rise in recent years, it is now gaining momentum. The aim is to gain more amplitude between spaces and use them for different functions: work and family environment.

Acoustic insulation is another of the problems that confinement has brought to light. Having materials that provide good acoustic conditioning, together with thermal insulation, are priorities nowadays, in order to avoid noise from adjoining dwellings or from outside.

Minimalist and natural decoration

 

A practical and simple style of decoration is sought, capable of adapting to all types of environments. We opt for materials that evoke nature and that help to take advantage of natural light.

Light tones such as Blanco Cristal or Gris Perla never go out of fashion, combined with darker tones to create a cosy atmosphere. For those looking for more intensity, Azul Noche stands out for its sophistication and elegance.

What do you think of the construction trends that will be the stars of 2022? Would you add any more? We’ll read you in the comments!

Granite solutions for greater energy efficiency

We are aware of the importance of constructing buildings that are efficient and environmentally friendly. Did you know that granite is considered one of the most efficient natural cladding materials in any architectural project? This natural stone has lots of advantages for sustainable construction. Read on to find out more in this article!

Among other qualities, granite has excellent thermal and humidity insulation properties, maintaining interior temperature, improving comfort and reducing energy consumption, especially when used outdoors as façade cladding.

Use of the granite in façade cladding

Granite is used in numerous construction projects. The façade cladding must guarantee three fundamental aspects:

  1. The maximum comfort of people.
  2. Resistance of the building to climate changes
  3. Energy saving

The insulation offered by granite in construction guarantees greater comfort inside the home and a saving in energy consumption, i.e., a reduction in heating and air conditioning costs. In addition, a building with a weather-resistant façade is much more durable and stable over time.

From a decorative point of view, granite offers outstanding performance when it comes to creating a customized façade. This material has a very wide chromatic diversity and countless options for adapting to different shapes and to other materials

Furthermore, far from being an old-fashioned building material, as a decorative resource granite can give a building a modern, sophisticated image that is excellently suited to the urban environment.

Projects in granite façades cladding

One of the most outstanding projects in the application of granite in façades is this building located in St. James Square, in the City of Westminster.

Granite transformation process: cutting and polishing

Before shaping countertops, stairs or pavers, granite must go through a transformation process, in which quality control is present at each and every stage. In this article, we invite you to learn step by step about the granite transformation process, paying special attention to the cutting and polishing phases.

The extraction of granite from our quarries

Most of the granite we commercialize at Grupimar are extracted from our quarries in Spain, Portugal and Venezuela. This extraction is made by cutting the granite with diamond wire or disc cutters.

Both its extraction and final finishes, it’s essential to be carried out with cutting tools, suitable for the precision and quality that a stone of great value, such as granite, needs. For this reason, at Grupimar we invest in incorporating the latest technological advances in every phase of the granite transformation process.

Some of the granite marketed is in block form. Those that have passed the quality controls are sent to the sawing process. On the other hand, those that are fractured are usually destined for the production of other smaller products such as kerbstones, perpiaños or paving stones.

Granite transformation process: cutting

In order to make the best use of the material, it is essential to calculate precisely which size is the most suitable  before cutting.

Traditionally,  the granite blocks were fed into the looms. Nowadays, with the latest innovations, they are used with wire-cutting machines, capable of making much more precise cuts and customising them according to our customers’ requirements.

The pieces that come out of this phase of transformation usually have a natural finish, but a little rough. Although it is sometimes marketed as a final finish, it is more usual to apply other treatments depending on the final use that the client wishes to give to the granite slab.

Granite transformation process: polishing

One of the most frequent finishes is polishing. Using polishers and diamond sandpaper, a perfect finish is achieved. The result is a smooth, shiny surface, which brings out the natural shine and colour of the stone.

For outdoor use, a flamed treatment is usually applied, which gives the granite a rough and vitreous appearance and is anti-slip.

Among other possible finishes, some of the most outstanding ones are the following.

– Bush Hammered. This is obtained by striking the stone with the bush hammer, a steel hammer with serrated teeth. It is also known as carving.

– Honing. This is achieved by applying an abrasion process in polishing machines, without achieving a total polishing effect.

– Sawing. The granite is cut with a steel strip or diamond disc until a flat surface with a certain roughness is achieved.

– Shot blasting. This finish is achieved by projecting stainless steel shot on the surface of the granite. Depending on the pressure applied, a finer or coarser finish is achieved. The surface has a uniform appearance with slight peaks and valleys.

Once the polishing process is finished and after applying the corresponding treatment, the granite pieces are classified according to the type of finish and material.

Finally, they are packaged for subsequent marketing.

Marcelino Group in Marmomac 2021

This is how our visit to the most important natural stone fair went

 

Marmomac, the benchmark trade fair for the stone industry, has returned to its on-site format and we could not miss this important international event.  It brings together the world’s main natural stone producing countries to showcase their products, but also to find the latest innovations and advances in machinery and technology for stone.

Due to the uncertainty caused by the Covid-19 pandemic, this year’s edition has combined the on-site format (called MARMOMAC) with the virtual format (MARMOMAC PLUS), a digital portal for the exhibition and search of producers and business contacts.

As it has been usual for more than 50 years, the on-site edition was held at the Verona exhibition centre (Italy) and confirmed the high level of internationality of the event.

According to Focus Piedra magazine, 45% of the 756 exhibiting companies came from outside the European Union, totalling 329 companies from 39 different countries. In particular, 80 companies have travelled from Turkey, 15 from Brazil, 11 from Egypt and 6 from Iran. These figures are also supported by numerous international delegations of buyers, architects and importers of slabs and technologies from the United States, Canada, Russia and the Maghreb (Egypt, Algeria and Tunisia), crucial areas for the development of exclusive and luxury projects.

It has been a very satisfactory experience in terms of business opportunities, as we cannot forget that the building materials sector is being affected by a crisis in the logistics sector.

Changes in consumer behaviour and global logistics crisis

 

Consumer habits have changed, online shopping and the demand for cargo space have skyrocketed. This has led to a peak in demand for products manufactured in China which, together with the reduction of personnel at ports, has led to an increase in logistics prices.

Thus, the costs of shipping a product to Europe from Asia are 10 times higher than in May 2020. In the construction sector in particular, there has been an average cost increase of 22.2%, which has led to numerous cancellations or stoppages of construction work.

After our experience at the fair and discussions with our customers, we wondered whether we should not create synergies and act together to try to change the length of the supply chain, promoting more local manufacturing, within the EU, to help reverse this logistics crisis and improve the European economy.

Despite the economic effort required to attend this fair with our own stand, at Marcelino Group we continue to invest in this type of event in order to consolidate the company’s image abroad, analyse what the competition is doing, promote our products and innovations and consolidate relations with new and existing customers.

Marcelino Group in Marmomac

From our time at Marmomac, we would like to highlight the joy that could be seen in both exhibitors and visitors.  We met again at an event, strengthening ties with partners, customers and suppliers in a warmer way than by sending emails or video calls.  We enjoyed every visit to our stand and the impressions we received from our catalogue of works and products.

Thank you Marmomac and see you in 2022!

Reasons why granite is the best choice for your building project

Appreciated by designers, architects and constructors, granite is a natural stone widely used in all kinds of construction projects both in interiors (bathrooms, countertops, kitchens, livingrooms…) and outdoors (facades, paving, swimming pools, public squares…). In this article we tell you why granite is still the best choice for your project.

Resistance and durability

Granite is one of the most heat and moisture resistant materials. Alos, thanks to its hardness, it does not scratch easily and remains unalterable for decades. This durability and resistance features makes granit the favourite option of the consumers for kitchen and bathroom countertops.

Excellent thermal and acoustic insulation

Granite is a natural stone that provides very effective thermal insulation, both against cold and to prevent overheating, which leads to an increased energy savings. Further,  it offers better performance in the event of sudden changes in temperature, preventing the appearance of dampness. One the other hand it also helps to insulate the home from outside noises.

Natural y sustainable

Granite is a natural material with a different formation process than other materials. There are no pieces exactly alike and that makes it unique.

Furthermore, this stone offers a longer life cycle. For its transformation it uses less energy than other materials and does not need chemicals. The result is a more natural product.

At Marcelino group we have a very strong commitment with the environment. Every rubble generated in the production of granite blocks are recycled and transformed into sandstone of different grain size. Later on these sandstones are supplied to concrete plants, terrazo factories, construction materials warehouses, etc., for their use.

Beauty and multiple finishes

Every granite piece has its own unique beauty and elegance. Surface finishes provide a wide aesthetic variety and decorative uses, creating sophisticated and stylish designs.

In our catalogue you will find a great granite range with multiple colors, textures and finishes coming from our quarries in Spain, Portugal and Venezuela. From classic tones like black, grey or white, to vibrating blue and green, going through warm earth red and yellow colours. Also you will find different textures: polished granite, aged, sawn, bush-hammered, etc. Whatever you need for your decoration we have the best option for you

A profitable investment

Thanks to its versatility, investing in granite is always a very profitable option. Granite tiles can be adapted to all type of formats, adapting to the construction requirements of each type of project. In addition, they are quick and easy to install.

Choosing granite is betting on quality and profitability. Like a work of art, granite gives elegance and sophistication that is hard to equal for other materials. Those who have tried it say that it is the best investment and that any construction is revalued.

A timeless and avant-garde material

Granite never goes out of fashion. Choosing granite for your construction is choosing a material that will keep its incredibles characteristics for a long time. Plus, new surface finishes allow granite to be adapted into contemporary designs.

How do we extract granite from our quarries?

An essential material for mankind since prehistoric times. Its presence in our daily lives, both in our homes in kitchen or bathroom worktops, and in cities, in paving, street furniture or sculptures, means that we are very familiar with it. But have you ever wondered how we separate the mass of granite from the mass of the mountain?

Granite is a plutonic igneous rock formed by the slow cooling of magma at great depths in the earth’s crust. It is made up of various minerals such as quartz, feldspar, mica, iron-titanium oxide or zircon; the first two being the essential minerals that give it great hardness and resistance to abrasion.

Throughout more than 50 years of experience in the sector, at Marcelino Group we have been modifying our way of extracting granite, using the most advanced machinery at all times.

The granite is extracted directly from our quarries, generally in the open air, and its extraction can be divided into several phases:

Primary cutting

In the initial stage, the so-called “primary cutting” has been perfected over the years. It consists of separating the rock mass from the mountain; until 1975, this extraction was carried out with explosives used directly in loose massifs, with the consequent waste of a large part of the raw material.

Between 1975 and the 1990s, the thermal lance was introduced, which was a blowtorch with a flame of 1,000 degrees centigrade applied directly to the massif. A groove 10 centimetres wide was made to disintegrate the granite. This technique is much more effective in extraction but very rudimentary, as it was used manually by the user and produced a lot of noise.

It was from the nineties onwards when diamond wire began to be used, thus making better use of the material, allowing automatic work and avoiding noise pollution.

Secondary cutting

After the primary cut, comes the second stage or “secondary cut”, where we make the blocks. Until 1980, drilling was carried out directly by hand by the operator with a hammer drill, which produced a lot of noise.

This mechanism was perfected years later with the appearance of multiple drilling, which consisted of attaching a grid with three or four hammer drills to a backhoe excavator.

The first versions were pneumatic, using compressed air. They made the work considerably easier, but they were very noisy and we depended on the air compressor.

From the year 2000 onwards, this technique was improved with the incorporation of the hydraulic multi-drill. This one has the same system but is totally autonomous, which facilitates mobility and causes less noise pollution.

Frontal machine

Once the material is extracted, the next step is to load the granite blocks. Until 1980, the blocks were loaded using fixed cranes. Years later, different implements were incorporated into the front loader which improved both the technique and the working conditions. Before 1980, it could take up to 2 hours to load a lorry, but thanks to the improvement in the implements, today we can do the same job in 5 minutes.

These implements are: the bucket, which is used to load tailings and earth; the grapple, which is used to move and load the blocks; and the extension, which is used to pull the benches.

Once the granite has been loaded, it is transported to the factory where the blocks are cut to the sizes and finishes required for each of our projects.

New trends in Urban planning

Despite of the fact that in the last year due to the pandemic and the advantages that remote-working gives us there’s more and more people that are taking chances and going back to rural; according to United Nations in its study “World Urbanization Prospects”, in 2050 about 6,700 million people will live in urban areas, that’s 60% of world population. This is why a sustainable urban planning model is needed today, with the capacity to generate social integration, well-being and at the same time create economic opportunities for its inhabitants.

The challenges that society has had to face over the past year due to the current health crisis have prompted cities to seek innovative solutions within their own capacities, needs and objectives.

Trends in urban planning are increasingly global, ecological and inclusive. Next, we present the most outstanding ones.

SmartCity

The SmartCity concept has been used for some years now, and is presented as a city where technology is at the service of citizens.

Some of the advantages it brings is automation in the management of urban infrastructures, which makes it more efficient, reduces energy consumption and costs, and improves services, mobility and citizen safety.

 

Sustainable cities

According to studies, energy consumption in cities will account for around 75% and greenhouse gas emissions will reach 80% of the total. Taking these figures into account, it is necessary to find tools to optimise resources, both in the services themselves and to tackle serious problems derived from energy consumption.

Although the search for alternatives in the sustainability of cities has been going on for many years, in the last year there has been an increase in social and political awareness for change and the focus has been placed on the adaptability and flexibility of cities in which the health of citizens is the main concern.

 

Green Cities

The main objective of the creation of green cities is to design cities with plenty of natural spaces and cultivated land in order to mitigate pollution, lower gas emissions, reduce noise pollution levels, construct sustainable buildings and educate the population to respect the environment.

In terms of street furniture, a commitment is sought to develop durable and resistant furniture, using natural materials such as stoneor wood, recycled or limiting energy consumption. At the same time, it is also sought that this furniture generates the least possible impact on people, for example, with the use of circadian lighting.

 

Mutable interventions

These are variable interventions, whose nature changes depending on the need or the moment. The most commonly used is street furniture that can change its location or shape. These are flexible urban plans, designed to last in the long term, but which at the same time allow the elements to be modified as the years go by, thus adapting to the needs of the citizens.

 

Adapting to our elders: collaborative housing

The world’s increasingly ageing population requires new needs to improve the lives of the elderly in cities. Therefore, more than ever, a sustainable, healthy and inclusive urban planning model is needed, with furniture adapted for everyone.

More and more cities are opting for cohousing or collaborative housing, where, in addition to adapting private homes to their needs, housing developments are created with common services, open-air spaces, with direct communication with health services, promoting respect and social inclusion at all times.

Cohousing seeks to end the isolation experienced by many older people by fostering solidarity, neighbourhood support and creating an active community based on trust.

Grupimar participates in the largest private real estate project in United States history

Grupimar participates in the largest private real estate project in United States history Grupimar participates in the largest private real estate project in United States history. We are talking about the new Hudson Yards neighborhood in New York, on the West Side of Midtown Manhattan, bounded roughly by 30th Street in the south, 43rd Street in the north, the West Side Highway in the west, and Eighth Avenue in the east. The hippest neighbourhood in the largest US metropolis is also known as the Far West Side.

It combines office space and luxury residences in six high-rise buildings with entertainment, art and its own school.

Grupimarwas part of this project by supplying more than 2,000 m2 of Azul Platino and Blanco Cristal granite flamed tiles, from Marma S.L. quarriesin Madrid and Extremadura.

We have gone to check first-hand the Azul Platino and Blanco Cristal flamed slabs that Grupimar supplied for the first phase of the Hudson Yards megaproject in New York. We are proud to be part of the Public Square and Gardens with our own granite”, the company shared on its social networks.
