The polyurethane foam as a representative nonaqueous reacted polymer grouting material has become one kind of advanced comprehensive performance material, and therefore it is necessary to research on its anti-permeability properties. According to impermeability grade method, polymer grouting materials are tested under different initial pressures and different densities. The results indicate that the density of polymer materials is generally at the range of 0.1g/cm3~0.3g/cm3 and the initial seepage pressure is at the range of 0.3~0.7MPa, which can bear 30 to 70 meters head pressure when seepage grouting is carried out in hydraulic engineering. According to the actual needs of different projects, polymer grouting amount is controlled to regulate the density of polymer materials to meet the need of different projects impermeability.
