Natural stone advice

As an element of nature the natural stone is very popular with customers and architects. Natural stone can be perfectly combined with other materials and provides each room an elegant appearance. Thanks to the variety of texture, color and appearance each stone is a unique specimen. By direct procurement, independence and always looking for the latest products, we can present you a variety of ideas. A constant drive for innovation using the latest technology such as water jet, robots and CNC machines, allows us a variety of new products and unique surface finishes.

Marble / limestone
Marble is a limestone. Marble is either pure white or tinted in different colors by metal oxides or other impurities and often penetrated by calcite veins. The higher the crystalline fraction, the more intense is the light transmittance.

Areas: living area, bathrooms in private areas 

Granite is a primary rock, which is caused by solidification of liquid magma below the surface. Granite is a very hard rock, unlike the marble. The quartz gives the granite hardness. Granite is more resistant and acid resistant. Most occurrences in Switzerland are titled as granite, which is actually wrong. What looks like granite and got dismantled in Switzerland is called gneiss. The composition is almost the same as granite, but the gneiss was under strong mechanical influences such as pressure, folding and rolling.

Applications: kitchen tops, fireplace benches, facades, coverings, outside seating areas.

The slate stone belongs to the deposit formation stones. The slate was corroborated and solidified by the deposition of fine clay, lime mud, with quartz grains under the pressure of rocks. The structure consists of many layers, hence the name slate.

Applications: flooring, coverings 

Quartzites are fine to medium grained metamorphic rocks, which are defined with quartz content of 98 percent. They are characterized by large resistance to environmental influences. Pure quartzite is mainly whitish-gray or white, such as the silver quartzite coming from Italy. Yellow and red color are caused by impurities of iron minerals. The frequently occurring yellow variants are caused by the existing mineral limonite from the primary rocks. Impurities of magnetite and pyrite quartzite is sometimes brown or gray, rare colors are dark green or gray-blue. The mineral dumortierite or kyanite stains the quartzites bluish to blue.

Application: flooring, coverings

Sandstone is a sedimentary rock (also "sedimentit") from cemented sand grains, which consist primarily of quartz. The sand grains are between 0,063 and 2 mm. With an increased concentration of other minerals the stone is called arkrose (with feldspars) or greywacke (with rock fragmants). When most grains are larger than 2 mm, then one speaks of a conglomerate (with rounded grains) or a breccia (with angular grains).

Application: coverings, moldings and columns

Basalt is a basic (SiO2 poor) effusive. It consists mainly of a mixture of iron and magnesium silicates with olivine and pyroxene as well as calcium-rich feldspar (plagioclase). Basalt is the volcanic equivalent of gabbro (plutonite), which has the same chemical composition. Basalt arises when low-viscosity, low-silica magma emerges on the surface and rapidly cooled to basalt. Basalt is usually dark gray to black.

Application: flooring, coverings
