When a client needs a pipe repaired, it’s the plumber’s responsibility to choose the best material for the project. Two of the leading materials for trenchless pipe repairs are CIPP and Thermoform. If you’re stuck trying to decide between PVC liners vs. CIPP liners, here are a few reasons why we recommend PVC.
The safety of your team is our priority. Thermoform liners are made of PVC-A. It cures with steam whereas CIPP requires a chemical reaction to cure. Steam doesn’t release any volatile organic compounds. It’s safe to work next to the Thermoform liner as it cures. The Thermoform liners are also safer for the environment. The steam cools into water, and there aren’t any off-gassed or leached chemicals to leak into the nearby groundwater or spread into the soil.
Ease of Installation
Even if the setup of the liner stalls due to unforeseen circumstances, it won’t be a problem for Thermoform. On the other hand, it can be an issue for a CIPP liner. If you’ve already mixed the resin and chemicals, you have a limited amount of time to apply them. Thermoform liners are always ready for the steam curing process. Any time is the right time to cure the PVC liner!
Rarely, a pipe liner may require removal. It’s not possible to remove a CIPP liner without removing the whole pipe. That’s due to the chemical bond between CIPP and the pipe. In contrast, steam softens Thermoform PVC liners for easy removal.
The materials you choose for a pipe rehabilitation project can affect your client’s satisfaction, the results, and the environment. When comparing PVC fold and form pipe liners vs. cured in place pipe liners, it’s best to use a data-driven approach to make a sound decision that focuses on safety and efficacy.
