Services

Our experts specialize in

Residential geotechnical engineering

Sampling, testing, and consulting for custom homes, hillside lots, and subdivisions so foundations sit on ground that is actually understood.

Commercial geotechnical engineering

Support for commercial pads, industrial sites, and land-use planning — from due diligence through construction observation.

Site exploration

Borings, test pits, and geologic mapping to identify hazards, collect samples, and describe subsurface conditions.

Engineering geologic reports

Site conditions, geologic hazards, and development constraints written for planning, design, and permitting.

Geotechnical engineering reports

Foundation, retaining-wall, grading, drainage, and pavement recommendations based on exploration and laboratory testing.

Slope and excavation stability

Assessment of slopes, excavations, and earthwork so cuts and fills stay stable through construction and occupancy.

Liquefaction and seismic evaluation

Seismic hazard analysis and liquefaction potential with practical risk-reduction recommendations.

Fault evaluation

Fault reconnaissance and geologic interpretation to support entitlements on sites with seismic sources nearby.

Soil and rock testing

Laboratory classification, moisture-density, and related ASTM testing of soils, aggregate, concrete, and asphalt.

Percolation and infiltration testing

On-site tests that inform stormwater design, drainage, and wastewater feasibility.

Field observation and testing

Grading observation, compaction testing, foundation observations, and daily field reports while the work is open.
