Laboratory Testing of Soil and Rock
Accredited laboratory services with constantly growing number of accredited tests supported by more than 90 years of expertise
SG Geotechnika laboratory was established by professor Alois Myslivec, Czech esteemed geotechnical engineer, as the first Czechoslovak soil mechanics laboratory in Prague in 1929. The laboratory is considered to be one of the best-equipped laboratories of its kind in the Czech Republic with the largest testing capacity and is constantly increasing number of accredited tests. We provide laboratory tests of soil, rock, construction and other materials such as products of burning or fill materials for former mines. The output is an assessment of site characterization, geotechnical design, quality control and performance assessments. We take part in several research tasks – including non-standard testing that allows a wide range of auxiliary test conditions to be defined.
