Advantages of Thermoform PVC Liner Over CIPP Liners

The materials chosen in pipelining projects make a difference not only in quality and efficiency but also the impact the project has on its surroundings and the environment. In many cases, the choice comes down to Thermoform PVC liners vs CIPP liners. The following is an overview and comparison of the two.

What is a Thermoform PVC Liner?

The Thermoform liners are made of PVC-A, which arrive folded in an H or C pattern. They restore sewer pipes by softening and expanding with exposure to steam and forming to the contours of the existing pipe’s interior. This newly-installed pipeline cools and hardens as a non-toxic and inert solution in a range of diameters from four to 36 inches.

How CIPP Works

CIPP, which stands for Cured-in-Place, also forms to pipeline interiors and prevents infiltration and exfiltration. A liner impregnated with an epoxy resin inserts in the existing pipe and expands with air pressure. The resin in CIPP, however, forms and hardens with a chemical reaction rather than cooling.

The Advantages of a Thermoform Liner

The major difference found when comparing Thermoform PVC fold and form pipe liners vs. cured in place pipe liners is that the PVC liner is the more ecologically-sound option. Unlike the CIPP process, the PVC liner doesn’t require chemicals for installation and doesn’t release harmful chemicals into the environment. The PVC liner can also be softened again with steam for simpler and cleaner removal.
