Gas tight sewage pipe Outgassing of flammable or explosive gases from the ground is a fact of life in former coal mining areas around the world. After coal mining has ceased and the mine workings have been ventilated, methane gas, for example, which is lighter than air due to its physical properties, strives to reach…
Areas with contaminated sites Especially in our industrial areas, areas are being developed again and again that are contaminated with impurities or even toxic substances. These impurities often cannot be adequately classified in detail. Wastewater systems in these areas are usually already made of highly resistant plastics. The elastomer seals alone are cause for concern.…
Ground settlements It’s tight in our cities! Not only above ground, but also underground, a number of supply and disposal lines and systems have to share space. Through renewals and repairs, the building ground is repeatedly broken up and moved. A standard-compliant piping zone cannot be realized in the rarest of cases or maintained in…

As a matter of principle, sewers and pipelines must…
