Our licensed Professional Engineers and Geologists carefully plan and self-perform geotechnical investigations and subsurface exploration for soil and rock classification by borings, test trenches and geophysical modeling. Field and Laboratory testing is performed in accordance with ASTM Standards in our AASHTO-accredited laboratory. Our reporting is compliant with jurisdictional requirements, and includes design recommendations for grading, excavation, shallow and deep foundations, pavements, retaining walls, septic systems, and seismic hazards such as earthquake faults, slope stability and liquefaction analysis.
