Cure-In-Place Piping (CIPP)
Cure-in-Place Piping (CIPP) Felt
Cure-in-place piping (CIPP) is a trenchless method that repairs failing pipes, from small residential water lines to large city sewer mains, without digging up and replacing the old system. It works by inserting a flexible felt liner inside the existing pipe, a pipe within a pipe, then curing it in place to form a safe, long lasting replacement.
Felt built for CIPP manufacturers
CIPP manufacturers are always seeking to improve the strength, flexibility, and price of their liners for both installation teams and end users. BIT supplies consistent, high quality polyester, polyester fiberglass, and 100% fiberglass nonwoven felt to CIPP manufacturers across North America. Choose standard thicknesses and densities, or a custom felt tuned to your brand.
Why CIPP is in demand
- Cost effective, since it avoids extensive digging and site restoration.
- Minimal disruption, which suits urban and sensitive areas.
- Faster installation once the liner is in place.
- Versatile across many pipe materials, diameters, and configurations.

Frequently Asked Questions
What is CIPP?
CIPP stands for cure-in-place piping. It is a trenchless repair method that inserts a resin saturated felt liner into an existing pipe, then cures it in place to form a new jointless pipe inside the old one.
What felt is used in CIPP liners?
CIPP liners use nonwoven felt made from polyester, polyester fiberglass blends, or 100% fiberglass. BIT supplies all three to CIPP manufacturers, in standard or custom thicknesses and densities.
Why choose trenchless CIPP over dig and replace?
CIPP avoids extensive excavation, which lowers cost, shortens project time, and reduces disruption to roads and property. It also works across many pipe types and sizes.
