Targeted rehabilitation in the shortest possible time
The short liner is a proven trenchless method for targeted rehabilitation of defective pipelines. It is particularly suitable for local defects and enables fast, economical, and permanently effective repair.
The system is based on an ECR glass fiber laminate that is impregnated with a silicate resin and adapted to the structural requirements of the respective damage case.
DN 100 – DN 800
Concrete, stoneware, cast iron, steel, plastic (except PE-HD)
Round and egg-shaped profiles
Renovation during ongoing operation is usually possible (dry-weather flow)
After thorough cleaning of the damaged area, a resin-impregnated glass-fibre laminate is positioned precisely in the damaged section using a pneumatic packer system.
The liner is pressed against the inner wall of the pipe and hardens there in a short time (cold curing). As a rule, the rehabilitation area is load-bearing again after just a few hours.
By using through-packers, wastewater operations can in many cases be maintained during the rehabilitation.
Everything else you need to know about the technology
The short liner is used when individual damaged areas need to be renovated locally and quickly, without renewing the entire pipeline.
Depending on the damage pattern, areas of approx. 0.5 to 4 metres can be renovated.
The short liner can be used in pipes made of concrete, stoneware, cast iron, steel, and plastic – but not in PE-HD pipes.
The entire renovation, including curing, usually takes only a few hours.
In many cases, yes. By using through-flow packers, dry-weather flow can often be maintained.
It offers a fast, economical, and durable solution for localised damage with minimal disruption to operations.
