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.

1. A method of repairing a manhole having at least one pipeline extending from a portion of the manhole, the method comprising: applying a mastic material to a lower portion of the manhole and at least partially into the at least one pipeline;positioning a manhole liner impregnated with a material capable of curing and hardening in the manhole;pressing the manhole liner against a wall of the manhole and the mastic material; andallowing the mastic material and manhole liner to cure and harden forming a single monolithic cured in place liner extending from the lower portion of the manhole into the at least one pipeline. 2. The method of claim 1 further comprising repairing the at least one pipeline by positioning a main pipe liner impregnated with a material capable of curing and hardening into the pipeline after the mastic material and manhole liner have cured. 3. The method of claim 2 wherein the main pipe liner is positioned in the at least one pipeline by inversion. 4. The method of claim 2 wherein the mastic material is applied by one of trawling, dispensing, painting, and slinging. 5. The method of claim 2 further comprising positioning an end seal between the main pipe liner and the wall of the manhole. 6. The method of claim 5 wherein the end seal comprises a tube and a flange extending about an end of the tube, wherein the flange is positioned at least partially in the manhole. 7. The method of claim 5 further comprising positioning a retaining ring between the end seal and the main pipe liner. 8. The method of claim 1 further comprising positioning a manhole bladder at least partially within the manhole liner and inflating the bladder to press the manhole liner against the wall of the manhole. 9. The method of claim 8 further comprising positioning a pipe bladder at least partially into the at least one pipeline to press the main pipe liner into contact with a wall of the pipeline. 10. The method of claim 9 wherein the manhole bladder and pipe bladder are removed after the materials have cured and hardened. 11. The method of claim 1 wherein the mastic material and materials impregnated into the manhole liner cure and harden at approximately the same time. 12. The method of claim 1 wherein the manhole includes multiple pipes extending from a portion of the manhole, and further comprising applying the mastic material into each of the pipes. 13. A method of repairing a manhole and a pipeline extending from a portion of the manhole, the method comprising: applying a mastic material capable of curing to a wall of the manhole and at least partially into the pipeline;positioning a manhole liner impregnated with a material capable of curing and hardening in the manhole, wherein the manhole liner includes a flanged portion which extends into a portion of the pipeline; andpressing the manhole liner against the wall of the manhole;allowing the mastic material and manhole liner to cure and harden forming a single monolithic cured in place liner wherein the flanged portion of the manhole liner extends from the manhole into the pipeline. 14. The method of claim 13 wherein the mastic material is applied by one of trawling, dispensing, painting, and slinging. 15. The method of claim 13 further comprising repairing the pipeline by positioning a main pipe liner impregnated with a material capable of curing and hardening into the pipeline after allowing the manhole liner material to cure. 16. The method of claim 15 wherein the main pipe liner is positioned in the at least one pipeline by inversion. 17. The method of claim 15 further comprising positioning an end seal between the main pipe liner and the wall of the manhole. 18. The method of claim 13 further comprising positioning a manhole bladder at least partially within the manhole liner and inflating the bladder to press the manhole liner against the wall of the manhole. 19. The method of claim 18 wherein the manhole bladder is removed after the materials have cured and hardened. 20. A method of repairing a manhole, comprising: applying a mastic material capable of curing and hardening about a lower portion of the manhole and any pipes extending from the manhole;positioning a first pipe liner impregnated with a material capable of curing and hardening at least partially into each pipe extending from the manhole, with the mastic material between the first liner and a wall of the pipes;positioning a manhole liner impregnated with a material capable of curing and hardening into the manhole, with the mastic material between a lower portion of the manhole liner and the lower portion of the manhole; andpressing the first pipe liners and manhole liner against the wall of the pipes and the manhole and allowing the materials to cure and harden forming a single monolithic cured in place liner. 21. The method of claim 20 further comprising repairing each of the pipes extending from the manhole by positioning main pipe liners against the walls of the pipes a distance further than the first pipe liners. 22. The method of claim 20 further comprising positioning a manhole bladder at least partially within the manhole liner, and expanding the manhole bladder to press the manhole liner against the wall of the manhole. 23. The method of claim 20 wherein the mastic material and materials impregnated into the manhole liner and the first liners are configured to cure at approximately the same time to form a monolithic repaired interior of the manhole.
