Our standard liner fits the most common pipe dimensions and projects for the trenchless renovation of drains, road culverts, or other pipes.

Inpipe Liner fit the most common pipe dimensions and projects for the trenchless renovation. 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 LINER

  • 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 installation
  • Visible laterals due to the flexibility of Inpipe’s liners – saves time for the installer
