Since the 1970s we have been operating a company-owned soil laboratory and an exploratory unit. We analyze and assess the distribution of grain sizes and the physical and chemical properties of the soil, such as grain shape, amount of lime, water content, water binding capacity, and soil consistency. We determine the soil density and carry out compression and shear tests.

In preparation for and accompanying the project, on-site we offer not only core sampling along with cohesive strength and vane shear testing, but we also offer plate load and permeability tests and determine soil density with the balloon method.

We use the latest equipment and provide you with expert and practical advice on all issues pertaining to soil mechanics and geotechnics.
