DN 1500 – Trenchless Rehabilitation with SAERTEX-LINER® MULTI

Rainer Kiel Kanalsanierung GmbH and SAERTEX multiCom® carried out a trenchless rehabilitation of a combined sewer with a nominal diameter of DN 1500 within an industrial area of the Dutch town of De Hemmen using a UV-cured GRP pipe liner, available from Pipe Core.

In order to pull the DN 1500 GRP liners into the gravity sewer, the manhole cones had to be removed beforehand. The liners were then pulled in directly from the truck using a conveyor belt and a 10-ton pull-in winch. UV curing was carried out using a particularly powerful light source, a 12 x 1000 watt jumbo light core.

Thanks to the advantages of trenchless CIPP (Cured-In-Place-Pipe) technology and the close cooperation of all project participants, the rehabilitation measure was successfully completed within a few days.
