From DN 80 mm to 500 mm
Protection of internal surfaces of water pipes with epoxy spray.
In 1997, a trenchless technology for rehabilitation of water pipelines was used for the first time – the M-System. This technology is applied when rehabilitating pipes of smaller profiles of DN 80 to 500, in particular in pipelines which, though waterproof, lack proper protection of the internal surfaces and decrease the quality of drinking water by discharging ions of iron into it and allow for the creation of sediments and.

Since 1992, the KAWO trenchless sleeving technology for rehabilitation of sewage headers has been the basic pillar of WOMBAT, s.r.o. As the name implies, the KAWO trenchless method is appreciated especially when excavation work poses problems, such as in the case of developed urban agglomerations, production company premises and hard-to-access pipelines. Notable is also the swiftness of the work – 50 to 200 meters can be covered per day – as well as its high quality, which ensures water-tightness of the reconstructed sections, while remaining.

The KAWEX trenchless technology is an inverse sleeve fitting technique for rehabilitation of underground water pipes of DN 200 to 1,000. The technology is used for repairs of leaking underground water pipes, where drinking water leaks out of the pipe into the surrounding area. Before the repair, a hydro-mechanical cleaning, a washout and an examination using a camera is performed. The technical procedure is similar to the KAWO technique used for rehabilitation of sewage headers. Differences lie mainly in the basic components used for lining..
