摘要 |
A lining for sealing the junction region where a lateral pipe and a main pipe meet. It has a two-portion structure including a main portion for lining a portion of the main pipe and a lateral portion of resin absorbent material for lining a portion of the lateral pipe. The main portion is sized for application to the full circumference of a main pipe on both sides of the junction and has an aperture for alignment with the opening of the lateral pipe. The lateral portion is connected to the main portion where it defines said opening and is gathered on a first side of the main portion.
