Keller Group
Our team specializes in deep foundations, ground improvement, excavation support, and grouting solutions designed for challenging Gulf Coast soil conditions, including soft soils, organic deposits, undocumented fills, and high groundwater environments.
Based in Houston, Keller supports projects throughout Eastern Texas and the Gulf Coast region. Our teams provide geotechnical solutions for petrochemical facilities, industrial plants, transportation infrastructure, marine developments, commercial construction, and flood protection projects.
Geotechnical expertise in Houston
Houston presents some of the most challenging geotechnical conditions in North America due to its young Gulf Coast sediments, soft soils, groundwater conditions, and ongoing subsidence concerns. Keller's Houston team has experience addressing:
- Soft and compressible Gulf Coast deposits
- Undocumented fills and organic soils
- High groundwater conditions
- Subsidence-related foundation challenges
- Petrochemical, marine, and industrial infrastructure
- Levee, embankment, and flood protection projects
