Based on the test results Sivec white marble from our quarry is a very compact (2850 kg/m3) natural stone with low open porosity (0,5%) and low water absorption (0,1%).
Its flexural strength (17,8 MPa) is high, which means, that it can be used also at very low thicknesses in general for flooring and cladding. Tests for resistance to freezing show no significant changes in flexural strength (-0,6% after 48 cycles). The material is therefore practically unchangeable in exposure to freezing.
Test results indicate that sawn surfaces are slip resistant in dry and wet conditions (SRV 74). Test results also show that the breaking load at the dowel holes on 3 cm thick tiles is 142 kg (1400 N) per dowel, so when supported by four dowels, these tiles can withstand a wind load of 568kg each.
Please note that stone is a natural product and all results are subject to variation.

The mineral composition of the stone provides advantageous mechanical characteristics. It is those characteristics that make Sivec very popular in countries with extreme weather conditions.
Comparative analysis has shown that Sivec is the most heat conductive stone among all. It superbly reflects sunrays and heat, which makes it stay cool to touch even at the highest temperatures. It is therefore very popular in hot places such as Middle East. Unique inner structure makes the stone resistant to frost and extreme cold and it is therefore widely used in Russia.
