Systems and methods for forming and deploying a pipe liner in a pipe main having a service lateral. The line is formed from three pieces of material. The piece of material forming the front top and of the main liner and the front of the lateral line has a cutout at the joint to reduce bunching, which can result in non-uniform liner thickness and may form obstructions at the joint.
