The activities of the geomechanics laboratory cover a wide range of laboratory and field tests on foundation soil samples and earth materials used in construction; the results of these tests form the basis for the proper design and execution of civil engineering structures.
In our accredited laboratory, we conduct laboratory and field tests on subgrade soil samples and earth materials in accordance with applicable regulations and professional standards. The results obtained provide a crucial basis for making sound design decisions, selecting optimal technical solutions, and ensuring the safe and reliable execution of construction structures. Through continuous investment in equipment and expertise, we ensure a high level of accuracy, reliability, and quality in all tests performed.
The laboratory has been accredited by HAA for over 15 years.
