LABORATORY

The activities of soil mechanics laboratory round off a wide range of laboratory and field tests of foundation soil and earth as construction material. The test results are a basis for proper design and construction of civil structures. The laboratory services include:

  • Field investigations and in situ tests at project sites,
  • Laboratory testing of materials, determination of physical and mechanical properties,
  • Control testing of materials and works during construction,
  • Laboratory Testing Report preparation,
