Abstract
An apparatus and method for sealing pipes or underground structures is provided. In one embodiment, the end of a pipe is sealed by the use of a pipe liner and a sealing member. The sealing member may be a hydrophilic material, a hydrophobic material, a compressible material, or a paste. The sealing member is held in place by a mechanical fastener and a liner is installed adjacent the sealing member and against the wall of the pipe or other structure to be sealed. In another embodiment, a manhole is sealed by the use of a sealing member, a mechanical fastener, and a manhole liner.
