Keller Group
CCR facilities present complex challenges driven by ash properties, groundwater conditions, and evolving regulatory requirements. Managing stability and seepage is critical to safe construction and long‑term compliance.
Geotechnical construction solutions for CCR facilities
Keller delivers geotechnical construction solutions for CCR facilities using an integrated design‑build approach.
Our work includes ash dewatering, groundwater cutoff systems, slope stabilization, environmental encapsulation, and earth support systems, supported by real‑time instrumentation and monitoring.
Keller's experience in CCR closure and remediation
Keller has worked on more CCR ash ponds than any other specialty geotechnical contractor, across a wide range of site conditions and ash characteristics. We partner with owners and engineers to deliver geotechnical construction solutions that support closure, remediation, and ongoing operation of CCR impoundments.
This experience enables predictable execution, regulatory compliance, and long‑term performance of CCR facilities.
Sector challenges we can solve
- Ash dewatering and drainage
- Groundwater control and seepage mitigation
- Embankment and slope stability
- Construction in sensitive ash materials
- Performance monitoring during closure
