Geotechnical Engineering in St. Tammany Parish, LA
St. Tammany Parish area sites trade pumpable backswamp clays against natural levee silts within one tract. Bearing, settlement, and swell questions on St. Tammany Parish sites get answered by data, before Louisiana foundations get sized on guesswork. Depth-to-rock data on St. Tammany Parish sites reprices foundations early, keeping LA construction inside the geotechnical envelope. We support St. Tammany Parish on a mobilization basis from Texas, partnering with Louisiana licensed professionals where sealed deliverables are required.

- Laboratory index testing: Atterberg limits (ASTM D4318), moisture content (ASTM D2216)
- Moisture-density relationships and bearing evaluation for foundations and pavements
- Expansive-soil characterization for slab and pavement design
- Construction-phase verification: proof rolls, subgrade acceptance, fill placement observation
FAQ · St. Tammany Parish
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.
