Soil laboratory testing

AMIGE have own soil laboratory available at its office. The laboratory is provided with all modern equipment of Russian and foreign manufacturers (Whykeham Farrance) necessary for determinations of physical and geotechnical soil properties as well as for chemical analysis of water and soil water extraction. Wide range of soil test instruments and great experience of the laboratory personnel allow soil test performance in compliance with both national (GOST) and international (BS/ ASTM) Standards.
