Complex Services of Laboratories of Soil and Rock Mechanics

The Laboratories of soil and rock mechanics have implemented the quality system in compliance with the CSN EN ISO/IEC 17025 and they are accredited by the Czech Accreditation Institute, o.p.s. for the basic geotechnical testing. (Accreditation Certificate No. 359/2000, Testing Laboratory Registration No. 1271.2)
