Keller Group
From levee systems and floodwalls to deep foundations and ground improvement, our team delivers solutions designed to perform in extremely soft soils and high groundwater conditions.
Based in New Orleans, Keller supports projects across Louisiana, including Baton Rouge, Lafayette, and coastal regions throughout the Gulf Coast. Our teams deliver geotechnical solutions for infrastructure, marine, and industrial projects in highly variable and challenging subsurface conditions.
Geotechnical expertise in New Orleans
The New Orleans region presents some of the most complex geotechnical challenges in North America. Keller’s local teams have extensive experience addressing:
- Extremely soft, compressible soils prone to settlement
- Subsidence and long-term ground movement
- High groundwater levels and flood risk
- Levee, floodwall, and coastal protection systems
- Marine and port infrastructure construction
These conditions require specialized geotechnical solutions to ensure structural stability, resilience, and long-term performance.
