Abstract
A method for installation of a flexible resin impregnable liner for lining a lateral pipe which leads into a main pipe having at one end a flexible collar for installation at the location where the lateral liner meets the main, wherein after installation the collar extends along the interior of the main seating against the opening of the lateral. The flexible liner is installed by inserting the liner into the lateral pipe and using fluid under pressure to expand the lining against the lateral wall to form seals with the collar at the lateral/main pipe junction.
