Do you have a project? We have the right liners. With diameters ranging from 40 to 1,400 mm, wall thicknesses between 2 and 41 mm, and single- or multi-layer construction. Our liners are available with or without a coating.
Exactly what you need.
We offer liners for pressure and gravity pipelines, for dimensional changes, and for profiles of all kinds! Maximum flexibility. The same goes for the curing methods available: hot water, steam, or UV light.
A particular advantage for you: Our liners can be manufactured in such a way that pipes with different diameters can be rehabilitated in a single pass.
High quality?
Earthquake-resistant.
Safety is paramount to you. You can count on our liners. They can even withstand an earthquake like the one that struck Japan in 2011. Prior to the quake, numerous supports had been retrofitted with our pipe liners, and they were inspected for damage after the earthquake. The result: The tested PIONEER®LINERs showed no signs of damage whatsoever. They are earthquake-resistant!
