Keller Group
Dams and levees require reliable subsurface performance to protect communities and infrastructure. Aging assets and seismic demands increase geotechnical risk. Whether your situation is typical or unique, Keller has the experience and innovation to help engineers, contractors, and owners identify and implement the best solution.
Geotechnical construction solutions for dams and levees
Keller provides a complete range of geotechnical construction solutions for new and existing dams and levees using a proven design‑build approach.
Our work includes seepage control through curtain and blanket grouting, cutoff wall installation, foundation stabilization through ground improvement, and seismic remediation to address liquefaction and lateral spreading risks. Keller also delivers solutions for sinkhole stabilization, earth retention, and foundation improvement to restore performance and extend the service life of critical water‑retaining structures.
Keller’s experience with dams and levees projects
Keller has completed hundreds of dam and levee projects across North America. Quality control has long been central to Keller’s dam and levee work.
We pioneered computerized data acquisition and remote control for grouting during the construction of Ridgeway Dam in Montrose, Colorado, in 1980, and we continue to use advanced verification and monitoring to confirm construction accuracy where performance tolerances and public safety are critical.
Sector challenges we can solve
- Seepage control and cutoff
- Seismic remediation and mitigation
- Sinkhole stabilization
- Foundation improvement
- Slide and overturning risk
