The Omega-Liner is a system developed for No-Dig renewal of damaged gravity sewers. The Omega-Liner is a patented material technology.
The Omega-Liner is a homogeneously extruded plastic pipe. The pipe is extruded to a circular shape, and subsequently it is folded so the cross section is reduced by 30-40%. The Omega-Liner is produced in stiffness class 4 and 8. The plastic pipe consists of PVC and various filling agents, which means that the pipe can be shaped at lower temperatures than for ordinary PVC pipes.
Before the folded pipe can be installed, it is heated in order to increase the flexibility. The folded pipe is pulled inside the existing pipe with a winch. When the Omega-Liner is in place it is heated by means of steam and together with low air pressure, it regains its original round shape. The installed pipe is equivalent to a new PVC pipe. The house connections are easy to locate and are opened by means of a robot and a CCTV camera. The Omega-Liner is a fast and reliable close-fit relining method for renewal of sewer and storm-water pipe.
Installation normally takes 2-5 hours. In general, it is possible to carry out 2-3 installations per day. To some extent, the installation time depends on the pipe length and diameter.
The Omega-Liner system has been part of our product portfolio since December 2015.
We are currently installing more than 20.000 meters pr. year.
