Groundwater control (also known as seepage control) involves the creation of barriers in soil, rock, or below-grade structures to restrict water movement. Keller provides the optimal solution to tackle each difficult groundwater control challenge.
- Provide seepage cutoff below dams and levees
- Prevent migration of contaminants
- Seal concrete joints or cracks in below-grade structures
- Restrict groundwater flow into excavations
- Dewater for excavations
- Water treatment
Controlling groundwater is often necessary where dry structures are below the groundwater table. This may involve sealing cracks and joints in buried concrete structures, such as tunnels or utility vaults. Dry excavations are often required below the groundwater table, necessitating a perimeter, and sometimes bottom, cutoff barrier.
