Inpipe Liner
Inpipe Liners fit the most common pipe dimensions and projects for the trenchless renovation of drains, road culverts, or other types of pipes. It is made of fiberglass-reinforced polyester, which is soft, flexible, and easy to handle during installation. Inpipe Liners are available in SN1 to SN7, depending on diameter. Available in Ø150 mm – Ø1800 mm.
Advantages of Inpipe Liners:
The right quality for your projects
- Thin walls thanks to high a E-modulus
- Lifespan of up to 100 years because of the low reduction factor
- Available for both inversion and winch-in-place READ MORE >
