It is important for pipeline rehabilitation methods to meet the challenges of preserving, maintaining and modernising underground pipelines in a cost-efficient, fast, safe and ecologically friendly way.

The focus is on trenchless rehabilitation methods. The choice of the most suitable rehabilitation method depends on a number of technical, commercial, ecological and even social factors.

In trenchless rehabilitation a distinction is being made between different lining technologies:

  • with annular gap (slipline technology)
  • without annular gap (close-fit lining)
  • burstlining (pipe bursting)
