• Polished Granite: This is the most shiny and reflective finish. It is used in spaces where maximizing brightness and highlighting the richness of granite colors is desired. Although very elegant, its intense shine may be too formal or not suitable for contemporary styles that demand a more sober aesthetic.

• Flamed Granite: This is obtained by applying a thermal lance to the surface of the granite, causing the grain to “pop.” It creates a rough texture. This finish is ideal for exteriors and areas where a non-slip surface is required, such as terraces or public areas, as required by the Technical Building Code (CTE-SUA). Unlike honed granite, which is smooth, flamed granite offers a coarser and more rustic appearance.

• Satin Finish Granite: This finish is among the most demanded. It offers a smooth surface but with some texture. It provides a slight reflection without being as matte as honed granite, making it an excellent option for those looking to give some personality to the product. Satin finish is popular in facades and interior cladding where an elegant but not overly shiny finish is desired.

• Granulated Granite: The granulated finish is executed through impacts of stainless steel balls under pressure, creating a rough and textured surface. Similar to the flamed finish, it is particularly suitable for outdoor applications where high slip resistance is needed, such as pavements and areas with heavy pedestrian traffic, complying with the standards required by the Technical Building Code (CTE-SUA). Its texture is much rougher than that of honed granite and slightly lightens the color of the material, making its use for indoor pavements less common.

Unlike wood, which can retain bacteria in its pores and fissures, or stainless steel, which despite its name can scratch and harbour bacteria in those scratches, granite retains its integrity over time.

Granite’s ability to withstand daily wear and tear without losing its natural beauty or hygiene is unparalleled. Materials such as laminate can deteriorate or peel over time, creating crevices where bacteria can proliferate. On the other hand, granite maintains a smooth, continuous surface thatcan be effectively cleaned and disinfected.

Granite applications

Granite in the kitchen: The importance of worktop hygiene

Far from being simple work surfaces, kitchen worktops become the epicentre of the home, where everyday life takes shape. Keeping these surfaces hygienic is essential to prevent the transmission of bacteria and to ensure the safety of the food we share with family and loved ones.

Such a surface must face daily challenges such as contact with hot elements, oils and frequent use of cutting utensils, which demands exceptional resistance. In this area, granite stands out for its heat tolerance, its hardness and its ability to repel most stains, marking a notable difference with materials such as marble or certain woods, which tend to be more vulnerable to damage and stains.

Granite in the bathroom: Cleanliness raised to the highest expression

The bathroom, a personal haven for grooming and relaxation, demands surfaces that not only reflect beauty, but also support impeccable hygiene. This is where granite, with its natural antibacterial properties, distinguishes itself as the ideal choice for worktops, sinks and floors.

Its robustness against humidity and the ease with which it can be kept clean make it the perfect candidate for environments that seek to combine functionality with refined design.

Care and maintenance of granite

To preserve the antibacterial properties and beauty of granite, it is important to follow some maintenance practices. For daily cleaning, we recommend the use of warm water and neutral soap, a mild solution that is effective without being harmful to the granite surface.

This is particularly important in kitchens and bathrooms, where frequent cleaning is essential to maintain a healthy environment. Avoiding the use of acidic or abrasive products is key, as these can damage the sealer applied to the granite and thus its stain resistance and surface integrity, preventing bacteria and micro-organisms from finding a place to proliferate.

By following these care and maintenance recommendations, granite worktops in the kitchen and bathroom will not only retain their beauty and durability, but will also continue to provide a hygienic and safe surface for the whole family.

Methods such as road development and the use of mast crane systems without trench development are employed to optimize loading equipment efficiency. These methods allow flexibility and adaptation to changing operational needs.

Initial Extraction

Mining begins with the extraction of the upper layer, removing overlying soil and non-mineral rock layers covering the deposit. Excavation and splitting methods are used to separate rock from minerals, involving manual tools, drilling, wedging, and controlled cracking techniques. These processes are fundamental for exposing mineral reserves.

Granite Extraction

The extraction process can be carried out through two methods. First, controlled drilling and blasting of large granite stone blocks. Second, using diamond wire cutting equipment. In both cases, the aim is to obtain manageable-sized granite blocks for transport and subsequent transformation.

Block Cutting and Lifting

Granite blocks are cut using diamond saws into specific sizes and shapes as needed. Tools like manual jacks, hydraulic stone machines, and push air bags are used to perform this crucial task. Precision and safety are essential at this stage. Lifting these blocks from the quarry floor is done using cranes and other heavy lifting equipment.

Cleaning and Waste Transport

Crushed stone that doesn’t meet block standards is transported out of the block processing plant for proper disposal. Proper waste management is vital to ensure the operation’s sustainability.

Environmental and Social Considerations

Extraction and mining in granite quarries must address environmental and social concerns. Changes in the landscape, dust and noise emissions, and involvement of local communities are critical aspects to consider. Planning and implementing sustainable extraction practices are essential to mitigate negative impacts and promote equitable development.
