Depth-to-rock data on Sioux Falls sites reprices foundations early, so SD foundations match the ground they sit on. Multi-state industrial clients bring us into Sioux Falls for defined programs, with professionals licensed in South Dakota engaged wherever the work requires.
- Soil borings and sampling programs sized to the structure and site
- Laboratory index testing: Atterberg limits (ASTM D4318), moisture content (ASTM D2216)

- Expansive-soil characterization for slab and pavement design
- Construction-phase verification: proof rolls, subgrade acceptance, fill placement observation
FAQ · Sioux Falls
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.
