LABORATORY ANALYSES OF SOIL AND ROCK SAMPLES

alt

Laboratory for Hydrogeology and Engineering Geology carries out analyses of physical, mechanical and insulating properties of soils and rocks for geological reports, and makes assessments and analyses according to the following standards: PN, EN, ASTM, BS, DIN and others. Analytical methods are chosen depending on the client’s need. We create a system of high quality analyses in order to receive the PCA accreditation certificate.

WE OFFER
