Our Feature

Perma-Liner™ Industries, LLC, the leading manufacturer and supplier of trenchless pipeline rehabilitation equipment and materials in North America, is beyond thrilled to be featured on Lifetime Networks’ Designing Spaces. Designing Spaces is an award-winning home improvement show that travels the country to remodel, redecorate and redesign the spaces we call home, including rehabilitating aging sewer systems for homeowners. Their mission is to educate, empower and to entertain their audience with informative solutions to fit their lifestyle. Perma-Liner had the incredible opportunity to showcase our affordable and innovative solutions to rehabilitating aging or broken pipes and the options homeowners have instead of excavating and digging up their beautiful landscape. Enjoy this episode of Designing Spaces and we hope you learn a little more about what we offer to homeowners when it comes to fixing that clogged or broken sewer pipe.

ASTM International is one of the world’s leading industrial standard-setting organizations and they recently announced a new standard for ASTM F3240, the standard practice for installation of seamless molded hydrophilic gaskets (SMHG) for long-term water tightness of cured-in-place rehabilitation of main and lateral pipelines. An SMHG is a single piece molded neoprene expansion gasket positioned between the host pipe and the liner. The gasket absorbs water and expands to form a long-term watertight seal between the CIPP and host pipe, which prevents infiltration and exfiltration.

How It Works

Old, failing sewer pipes can be rehabilitated without excavation

A resin-saturated felt tube made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). It is possible to invert the liner upstream (e.g. from the downstream access point) but this carries greater risk. It is possible to install a liner from the downstream access point, upstream to a blind end however this carries the highest risk of all the CIPP installation methods. Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional “dig and replace” pipe repair methods.
