1. A method of repairing a main pipe and a lateral pipe connected thereto and in communication therewith to form a pipe juncture, comprising:
taking a liner assembly comprising a main liner member and a lateral liner tube in communication with one another at a liner juncture;
impregnating the liner assembly with a material capable of curing and hardening;
applying a paste proximate the liner juncture of the liner assembly;
positioning the liner assembly at least partially into the main pipe after applying the paste;
positioning the lateral liner tube against the lateral pipe and the main liner member against the main pipe; and
allowing the material capable of curing and hardening to cure and harden;
wherein the paste forms a gasket to seal an area between the liner assembly and the pipe juncture.
