Our Services

Tight-fit sliplining
Tight-fit sliplining is suitable for water mains and pressure sewers when the pipe diameter must be maintained or increased. The result is a continuous pipe that can be tapped afterward. The work requires access at both ends of the rehabilitated pipe.Sliplining
Sliplining is suitable for water mains and sloped or pressure sewers when the pipe diameter can be reduced. The result is a continuous pipe. The work requires access at both ends of the rehabilitated pipe.Deformed/reformed liner
This method is suitable for water mains and pressure sewers when the pipe diameter cannot be significantly reduced. The result is a continuous pipe that should preferably not be tapped afterward. The work requires access at both ends of the rehabilitated pipe.Directional drilling
Directional drilling can be used to replace an old water or pressure pipe or in new construction. The ground must be suitable for drilling. Random rocks and other obstacles can be bypassed since the drill is steerable. River crossings, for example, are possible. The result is a continuous pipe that can be tapped afterward. The work requires access at both ends of the installation section. -
CIPP lining
CIPP lining is suitable for sewers where the pipe diameter cannot be significantly reduced. A new pipe is installed inside the old one. The work is usually done through existing inspection chambers, so excavation is generally not needed.

The carbon fiber liner is inserted into the damaged pipe, cured with steam, and the result is a seamless structure that adapts to the thermal expansion of the original pipe.
