ABSTRACT:
An improved tubular lining hose for use in softlining pipe rehabilitation which includes the novel use of a layer of reinforcing fibers to reinforce the lining hose. In a preferred embodiment, a layer of reinforcing fibers, such as fiberglass, is encapsulated between layers of resin absorbing material saturated with resin. The saturated resin absorbing layers form a protective veil around the reinforcing fibers and protect the reinforcing fibers from water and other corrosive materials.
