Trenchless Lining – Manhole to Manhole.
When main lines leak or corrode, they can damage above ground surfaces, cause pollution, and start severe flooding in treatment facilities. With Perma-Main™, we use the most technologically advanced cured-in-place pipe (CIPP) lining to rehabilitate city pipes.
Digging causes environmental damage, longer-term traffic disruptions, and is very expensive, but with Perma-Main™ products, there is less disruption, less cleanup, and less cost. Created for municipal main line sanitary sewers, our certified, third-party tested equipment and materials are engineered and manufactured to meet project specifications on an individual basis. Our high performance products are consistent in producing results that work, and are very user friendly.
Our Perma-Main™ liner is a non-woven, needle punched felt. Stitched and tape seamed. 3mm-45mm, PP or PU coating. 6”-24” diameters available.
