One of the main advantages of granite used for facing facades, - durability of the coating. The best proof of this - thousands of buildings throughout the world, faced with granite and did not change its appearance over the centuries.

The quality of granite is strongly influenced by the manner in which it is produced. There are three main ways to extract the stone. Most of them are amateurish and, unfortunately, the most common - production by the explosion. In rock drilling by doing is a deep hole, where lay the charge and undermined. Among the breakaway pieces of rock are selected by the largest blocks, which are then cut into slabs. Advantages of this method of extraction of stone lies in the fact that it is extremely cheap. But the disadvantages outweigh this advantage.

Breed of granite - granite, syenite, diorite, gabbro, labradorite, monocytes, teshenity, granite, etc., formed by the eruption of magma and its introduction into the voids crust at a considerable depth. As a result of slow cooling of the overlying strata under the pressure of the earth, these rocks are well crystallized and have a strong holocrystalline, usually granoblastic texture.

Granite - acidic intrusive igneous rock. It consists of quartz, plahyoklaza, potassium feldspar and mica - biotite and / or muscovite. Granites are widespread in continental crust. Efuzyvni analogues granite - ryolytы. The density of granite - 2600 kg / m ³, compression strength of 300 MPa.
