Reinforcement

In the traditional CIPP process, the uncured resin is impregnated into an unwoven felt fabric which essentially serves to hold the resin in place while the liner is installed in the pipe. The felt fabric does not contribute significantly to the strength or modulus of the liner once the liner is cured. However, it is also possible to use woven fabrics with greatly enhanced structural properties. These can be designed to allow thinner liners or liners with superior strength and modulus properties.
