Geotechnical Laboratory

The Geotechnical Laboratory, equipped with modern testing instruments, provides quality control of soil materials to determine their physical and mechanical properties, as well as to assess the existing condition of the terrain.

Based on the performed laboratory tests and the obtained results for the material properties, and through comparison with the required criteria, an evaluation of the suitability and usability of the materials is carried out for the necessary construction layers, including:subgrade layers,fill materials,base (tampon) layers.

This process ensures reliable and controlled application of soil materials throughout all phases of construction activities, providing stability, load‑bearing capacity, and long‑term durability of the structures.
