Relining is a sewer lateral Rehabilitation method. The system was developed for relining small diameter pipes in diameter range from 2? to 8?. Any pipe material can be relined.
Relining uses PVC-coated fiberglass reinforced polyester needled felt tube filled with liquid resin. The impregnated liner tube is inverted using an air inversion unit. This system is a true inversion technique using compressed air. The resin impregnated liner tube is inverted (turned inside out) and pressed tightly against the host pipe until cured. The end result is a PVC continuous liner with no joints and seamless from end to end.
Advantages of Relining:
Reduces the potential for damage to other underground utilities associated with dig and replace methods.
Repairs damaged lateral service pipelines and restores structural capacity without extensive excavation or replacement.
Eliminates street excavation, paving and concrete repair costs, and traffic control. |
