Abstract
A process for sealing underground walls so as to prevent water from seeping through the walls. A hollow pipe is inserted at a first position and a sealant material is injected through the pipe to effect a seal between a footing and the bottom of the wall. The hollow pipe is withdrawn vertically and progressively while injecting additional sealant material. Thereafter, the hollow pipe is indexed laterally and the wall sealed as before from the footing to grade level and this procedure is repeated until the entire underground wall is sealed externally. In a modified form of the invention, the hollow tube is withdrawn and then the sealant is applied through the opening created by the insertion and withdrawal of the hollow tube.
