Abstract
An assembly and method of sealing a junction of a pipe and a second structure are provided. The assembly includes a pipe liner having a tubular portion and a brim portion, and a mechanical anchor adapted to secure the brim portion of the pipe liner to the second structure. The assembly may further include a compression gasket for placement between the pipe liner and the pipe or second structure. The compression gasket may comprise a hydrophilic material, a hydrophobic material, or a compressible material. The methods of using the assembly include, but are not limited to, the use of a cured-in-place pipe liner.

An assembly for sealing a junction of a pipe having a surface and a second structure having a wall with a thickness, said assembly comprising:
- the pipe extending outwardly from the second structure at an angle;
- a resin impregnable pipe junction liner having a tubular portion positioned against and inside the inside surface of the pipe and a brim portion at an inside surface of the second structure;
- the brim portion being positioned against the second structure;
- wherein the brim portion is located at a junction between the pipe and the second structure and extending away from the junction along the inside surface of the second structure;
- and
- a mechanical anchor penetrating through the brim portion and the second structure;
- wherein the second structure is one of a pipe and a manhole.
