BurrowLine GRP Liner Flex is built for rehabilitation projects where standard circular liners don’t suit the pipe profile — special geometries, arch renovation, variable cross sections, and dimensional changes.

It is a prefabricated GRP liner, ready for installation, with the existing pipe condition factored into the rehabilitation design. Installation uses a folded inner film for safe insertion, and neither the insertion direction nor the location of a dimensional jump need to be known in advance. This suits contractors, councils, and infrastructure teams needing a tailored approach to complex pipe renewal work.
| Dimension range | DN250 – DN1600 (Flex XL) |
|---|---|
| Profile options | Circular and oval, sized to project requirements |
| Installation | Folded inner film for safe insertion |
When the pipe run has special geometries, changes cross-section along its length, or needs an arch or oval profile that a standard circular liner can’t follow.
No — it’s designed so neither the insertion direction nor the jump location need to be known beforehand.
