Abstract:
A method of repairing a manhole is provided. A mastic material capable of curing and hardening as applied to a lower portion of the manhole, including the barrel, bench, and into at least one pipe line extending from the manhole. A resin saturated liner may also be included into a portion of the pipe extending from the manhole. A manhole liner saturated with a resinous material is then positioned in the manhole, and the manhole liner, pipe liner, and mastic material are configured to cure at approximately the same time to form a homogenous, repaired interior of the manhole, including a portion extending into the pipe. The pipe or pipes can then be repaired in a manner such as inverting a liner or bladder into the pipe. In the addition of an end seal at the juncture between the pipe and manhole is also contemplated for further sealing the juncture.
