Systems and methods for pipe lining systems and methods of use are described. Systems and methods may include a CIPP lateral liner that is inserted into a bladder forming a CIPP liner assembly that can be inserted into a pipe line for a pipe repair. CIPP liner assembly can include a membrane that produces superior results compared to the prior art. A backing ring may be used with these systems and methods.

A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

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.

A new, innovative tool useful in fluidly coupling a lateral pipeline to a reinstated pipeline containing a continuous liner is provided. The pipeline reinstatement tool includes a flexible shaft that is coupled to a cutting head at a first end and a coupling assembly at a second end. The cutting head includes a hollow cylindrical member having cutting teeth that project longitudinally from the first end of the hollow cylindrical member. The tool includes a first compressible tensioner portion disposed about the flexible shaft proximate cutting head, a second compressible tensioner portion disposed about the flexible shaft proximate the coupling assembly, and a flexible sleeve portion disposed about the flexible shaft between the first compressible tensioner portion and the second compressible tensioner portion.
