Geotechnical Investigations

The subsurface investigations are performed using truck-mounted equipment. Subsurface work is logged by engineers or geologists. Testing, and report generation are done in-house, from our state-of-the art, Geotechnical Laboratory. The GeoMat’s staff recommends the foundation criteria and suggest the cost effective foundation system for the projects. GeoMat services can be tailored to assist and/or meet our client’s specific project requirements.
