Geotechnical Testing Program

The Geotechnical Testing Program was established to provide conventional and specialized testing of all types of soils and geosynthetic clay liners to establish their engineering properties (physical, mechanical, and hydraulic properties) for design and construction-related purposes. Some of the testing services performed within the Geotechnical Testing Program are presented below.
