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.

Tubing everting apparatus, assemblies, and methods are disclosed herein. The tubing everting apparatus include a pressure chamber that defines an internal volume, a liner inlet port that is configured to receive a flexible tube liner into the internal volume, an inlet sealing structure that is configured to resist fluid flow therepast from the pressure chamber, and a liner outlet port that is configured to permit the flexible tube liner to extend from the internal volume. In some embodiments, the apparatus include a lubricator that is configured to apply a lubricant to the flexible tube liner. In some embodiments, the apparatus include a non-deflation valve that is configured to selectively transition between open and closed states. The assemblies include the apparatus and a cart that includes a lubricant reservoir. The methods include methods of operating the apparatus.
