Groundwater control involves the creation of barriers in soil, rock, or below-grade structures to restrict the movement of water. 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
Dams and Levees often require a cutoff wall along their alignment to control under seepage. Perimeter cutoff walls restrict the spread of contaminants from polluted sites. The control of groundwater is often necessary where dry structures are needed 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, which necessitates a perimeter, and sometimes bottom, cutoff barrier.
