The junction between the mainline and lateral pipes has been identified as the weakest point in the sewer system. These junctions are often found to be structurally unsound. Our system will allow for any combination of mainlines from 8-24 inches and lateral lines from 4-8 inches. The lateral portion of the liner is inverted up the lateral from the mainline sewer to lengths in excess of 100 feet.
The LFS Junction Liner employs many quality control features, such as ASTM F1216 design, vacuum impregnation, inversion installation, and protective carrying devices. These features ensure product uniformity, strength, durability and affordability for the end user. There is no joining of two separate liners required. The LFS junction Liner is inserted through the mainline pipe and once positioned, the liner is then inverted up the existing lateral. The end result is a one-piece, structurally sound repair of the connection and lateral.
Both the mainline and lateral portions of the liner are installed simultaneously as a one piece LFS Junction Liner, resulting in a smooth interface of the lateral/main connection. The new liner ensures high quality and durability that is impervious to infiltration and root intrusion.
