Ground Water Control
Ground water control is an important factor on many sites to control erosion, prevent migration of contaminants, or keep ground water from entering excavations or below grade structures. Jet grouting and soil mixing prevent the migration of contaminants. Compaction grouting fills voids and fissures to reduce seepage. Cement and chemical grouting create grout curtains for seepage control beneath dams. TRD constructs continuous cutoff walls with very low permeability. Polyurethane grouting seals concrete joints.
