Over the last 40 years, cured-in-place-pipe (CIPP) technology has become the method of choice for the rehabilitation of deteriorated underground pipelines and sewers. That’s because it’s less expensive than traditional open cut methods and is relatively fast and easy to install.
Part of what has contributed to CIPP’s success is the resins used in the adhesion process. The most common of these are made with polyester and epoxy. Typically, polyester gets used with felt linings and epoxy with fiberglass ones.
The main advantage of polyester resins is that they are less costly. But they also have a tendency to fracture more easily and lack the durability of epoxy resins. Where flexible high-strength bonding is required, epoxy wins, hands down.
Polyester resins are also problematic in the fact that once cured, if the cure is incomplete or too much hardener has been added to the mix to speed it up, they can discharge excess styrene, a chemical that can harm the environment. Epoxy resins are a greener alternative because they produce no toxic substances.
Formadrain uses only fiberglass/epoxy liners in all CIPP projects. That’s because our company believes that to do quality rehabilitation work, you have to begin with superior materials.
Our liners NSF (National Sanitation Foundation) 14 certified, they actually exceed the minimum standards of ASTM F1216 five times over. This guarantees reliable, long-term performance, even where smaller pipes are concerned.
Formadrain has been a leader in pipe lining systems technology for almost 20 years. We got that way because our engineers are dedicated to staying on top of the latest and best in no-dig innovations. When you need trusted CIPP solutions for your residential or municipal pipe systems, contact us!
