UV-Liner – light in the pipe rehabilitation

The product

With a light-curing pipe liner, D&S-Rohrsanierung has completed its wide range of products. It is a multilayer, corrosion- and chemical-resistant GFKLiner, which is provided with an outer foil and an inner foil. The liner is available in wall thicknesses from 3.0 to 29.6 mm. UP resins according to DIN 18 820 with moulding properties according to DIN 16 946-2 are used as reaction resins. This is mixed with UV initiators.

All materials as well as the installation process are subject to internal and external monitoring as part of a quality assurance plan. The company thus has at its disposal all the currently common processes in which pipe liners are cured either with steam, with water or with UV light.


The field of installation

No matter whether round, angular or ovoid - the process can be used for defective sewer pipe systems in practically all common pipe cross-sections in a nominal width range from DN 150 to DN 1900 and egg-profiles from 200/300 to 1200/1800.
