In large urbanized areas tunnels are often made use of for different purposes; examples are underground railways, sewage tunnels and air raid shelters. Since most of the ground surface in such areas is covered and drained to sewers, such tunnels can exert a considerable drainage effect and lower the subsoil water table, with consequent damage to houses and installations. The laboratory tests on the penetration of grouts into sand and narrow gaps, which are described in National Swedish Building Research Report R45:1970, have been supplemented using new grouts and performing tests at lower temperatures. Limited field tests were performed in a rock tunnel of approximately 6 sq m cross section in order to find what degree of impermeability can be achieved using chemical grouts of low viscosity and high penetration capacity. /Author/
