TECHNOLOGY

The rehabilitation technology for challenging shapes 

Deposits, ageing and corrosion pose a threat to pipelines all around the world. The conservative approach to pipeline repair by means of excavation is expensive, time-consuming, noisy and generally causes traffic disruptions.

SEKISUI´s patented, certified, award-winning trenchless technology is perfect for gravity pipe networks − providing solutions that are high quality, cost-effective and environmentally friendly.

The Spiral Wound lining technology is being employed successfully all over the world for the rehabilitation of challenging circular and custom shapes and is proving its reliability even under extreme conditions.

Trenchless pipe rehabilitation with Spiral Wound lining: unique and competitive 

SPR Windingmachine Egg ShapeThe Spiral Wound lining method is used for the rehabilitation of gravity networks. This trenchless technology is based on the principle of spiral winding an extruded plastic profile from PVC or HDPE into a liner.
The profiles with high ring stiffness and low weight can be steel-reinforced if needed.
Directly in the host pipe the single profile strips will be joined together by using a special winding machine and will form a liner.
Depending on the system, the host pipe will be rehabilitated with a close fit liner or a liner with a backfilling of a high performance grout. The result is a loadbearing, homogeneous and watertight pipe system.
The spiral wound lining method is suitable for a wide range of diameters and shapes. Installation can be carried out without excavation and without interrupting the flow in the line, so that in most cases, there is no need for bypass pumping.
