Slope Failure Monitoring Programs
Service websiteGES establishes instrumented monitoring programs for slope failure and surcharge fill, including inclinometer installation and seismograph vibration monitoring.
Geophysical Surveys
Service websiteGES conducts seismic refraction evaluation and electrical resistivity surveys to characterize subsurface stratigraphy and groundwater conditions.
Drilling Services
Service websiteGES operates three CME drilling rigs with OSHA-certified crews for auger borings, Standard Penetration Test sampling, thin-walled tube sampling, diamond core drilling, and piezometer installation. A barge-mounted CME-45C rig handles marine and navigation channel projects.
Earthwork and Materials Testing
Service websiteGES operates a full-service laboratory certified by AASHTO and the U.S. Army Corps of Engineers. Testing capabilities include grain size analysis, Atterberg Limits, Modified and Standard Proctor compaction, California Bearing Ratio, concrete core strength, rebar tensile strength, and chloride ion testing. Seven field technicians provide nuclear gauge earthwork and construction supervision.
Structural Material Evaluation
Service websiteGES evaluates existing structural elements using concrete core sampling, Ferroscan rebar detection (Hilti PS200), half-cell corrosion potential surveys, and steel bar testing for grade and tensile strength.
Weld Inspection
Service websiteGES performs inspection and integrity testing of welds.
Environmental Studies and Storm Water Management
Service websiteGES conducts environmental studies and develops storm water pollution prevention plans in support of site development and permitting requirements.
