Ground water control (also referred to as construction dewatering) includes various applications to keep ground water from entering excavations or below grade structures and control erosion. Jet grouting and soil mixing is used to prevent the migration of contaminants. Compaction grouting fills voids and fissures to reduce seepage. For seepage control beneath dams, cement and chemical grouting are used to create grout curtains. Cut off walls are used in areas with very low permeability. For concrete applications, polyurethane grouting is used to seal off joints.
