Cement-based or chemical grouting materials are the foremost choice to seal water-bearing areas in subsoil or rock efficiently. Anti-wash out resistant cement-based grout mixes and water-reactive grouting materials based on polyurethane are the preferred material for pre-excavation grouting. However, adequate equipment and material technology nowadays enable controlled processing of combined cement-polyurethane grout mixes, which withholds the benefits of both materials types.
