FAQ

Granite – igneous rock (result of the cooling and solidification of magma), basically formed of quartz (colorless material), feldspar (responsible for the variety of colors) and mica (gives the rock shine). Other minerals such as amphiboles (hornblende), pyroxenes (augite and hyperstene), olivine, zircon, among others, can also be found in granite.

This rock is a success in the field of civil construction because its set of minerals guarantees:

– High level of hardness (resistance to scratches and scratches);

– Low porosity and permeability (difficulty for liquids to permeate the rock);

– High level of durability

– Thermal stability (resistance to temperature changes);

– Variegation (variety of colors and movement)

Marble – metamorphic rock (originating from the physical-chemical transformation when exposed to high temperatures and pressure). The predominant mineralogical composition is calcite. Its color is more uniform with the formation of well-defined veins.

– Low level of hardness

– High porosity and permeability

– Thermal stability (withstands high temperatures)

Quartzite – metamorphic rock (originating from the physical-chemical transformation when exposed to high temperatures and pressure). Basically composed of quartz, the rock may contain other elements such as muscovite, biotite, sericite, tourmaline and dumortierite.

– High level of hardness (resistance to scratches and scratches);

– Low porosity and permeability (difficulty for liquids to permeate the rock);

– Thermal stability (resistance to temperature changes);

– Variegation (variety of colors and movement)

The application of these materials in civil construction projects will depend on the physical-chemical properties that their mineralogical structures guarantee to the rocks. Each one will have its best use according to its characteristics.

Marble: fireplaces, walls, floors, partitions, facades and countertops.

Quartzite: countertops, floors, walls, fireplaces, tables, thresholds.

Granite: covering floors, walls, facades, countertops, sinks.

The use of natural rocks in architectural projects dates back to ancient civilizations, such as the Egyptians and Sumerians. Even after millennia, the use of rocks is still strong due to the physicochemical properties that the formation processes guarantee to these materials. Currently, with the advancement of industrial techniques, the possibilities of applying natural rocks in architectural projects have been expanded, being used on a large scale.

Depending on their composition, natural materials will present different physicochemical properties and therefore are suitable for different types of application. The necessary rocks to meet the specifics of the project must be sought. Resistance, durability, porosity, permeability, among others.

The look of natural rocks is unique. According to the rock formation processes, each plate will have its unique design carved by nature. It is impossible to find a plate with the same design as another. Exclusivity is the detail that makes all the difference.

The maintenance of natural rocks is extremely easy. Only with cloths and water it is possible to remove any type of residue. If necessary, it is advisable to apply a small dilution of neutral pH detergent.
