Geotechnical Engineering in St. Louis, MO
St. Louis area river-bottom clays pump under compactors wet of optimum. Subsurface investigation turns St. Louis geology into usable design numbers, giving Missouri designers the inputs calculations actually need. Consolidation and strength testing on St. Louis samples quantify settlement, keeping MO construction inside the geotechnical envelope. Multi-state industrial clients bring us into St. Louis for defined programs, with professionals licensed in Missouri engaged wherever the work requires.

- Expansive-soil characterization for slab and pavement design
- Construction-phase verification: proof rolls, subgrade acceptance, fill placement observation
FAQ · St. Louis
Do I need a geotechnical report before building?
Most commercial permits, lenders, and structural engineers require a geotechnical report to establish allowable bearing pressure and foundation type. It is the least expensive insurance a foundation can have.
How long does a geotechnical investigation take?
A typical light-commercial site runs one to two weeks from drilling to final report, depending on lab test turnaround and access conditions.
