PERMA
LINING
Repairing
wastewater pipes is a time-consuming, expensive, and disruptive
activity. Typically, it requires extensive excavation, traffic
control,
and new paving or concrete repair. Also, there is the potential
for damaging other underground utilities located in the vicinity
of the repair. Now, there is a simpler and easier solution
called perma lining.
Perma lining
is a sewer lateral rehabilitation method developed for relining
small diameter pipes in diameter range from 2" to 8".
Any pipe material can be relined.
Perma lining uses a PVC-coated fiberglass reinforced polyester needled felt
tube filled with liquid resin. The impregnated liner tube is inverted 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.
