Geotechnical Services

Geotechnical engineering is the branch of civil engineering that employs scientific methods to determine, evaluate, and leverage the relationship between geological environments and engineered works. This discipline encompasses soil-structure design and construction involving earthern materials. Our geotechnical engineers are proficient in the application of soil and engineering mechanics, subsurface exploration methods, and laboratory investigation techniques.
