Geosynthetic Practises In The Revetment Foundation
Geosynthetic Practises In The Revetment And Unpaved Roads
Various in-situ tests and geotechnical instrumentation works are performed according to the importance and requirements of the projects. Mechanical properties are determined, and the structure-soil relation is monitored during soil investigations and geotechnical engineering construction. We have the capacity to perform a wide variety of in-situ tests (CPT, SPT, plate loading, sand cone, inclinometer, geophysical measurements).
