Fiberglass CIPP Liners
Glass-fiber reinforced liners deliver high strength in a thin wall, a good fit when diameter matters and the host pipe needs real structural help.
The details, in plain English.
Fiberglass liners use woven or stitched glass fabric instead of, or alongside, felt. After resin saturation and curing, the glass gives high stiffness and strength with less wall thickness, which preserves more of the pipe's flow area.
They are a good option for larger diameters, deteriorated host pipes, storm lines and projects where a thinner structural liner is desirable. We choose between felt and glass-fiber liners based on loads, diameter and cure method.
Best for
- Larger diameter mains
- Deteriorated host pipes needing structure
- Storm and culvert lines
- Projects where flow area matters

Questions, answered
Is fiberglass stronger than felt?
Glass-fiber liners can reach a given strength with a thinner wall. Both are engineered to the job, and the right choice depends on the pipe.
Do fiberglass liners cost more?
They can, depending on size and project. The estimate shows the options.
