Deposits, leaking joint cracks, aging and corrosion pose a threat to pipelines. The conservative approach to pipeline repair by means of excavation is expensive, time-consuming, and noisy and can result in major traffic disruptions.
SEKISUI SPR’s patented, certified, award-winning trenchless technology is perfect for water, pressure sewer or gravity pipe networks − providing solutions that are high quality, cost-effective, and environmentally friendly.
Our vast range of trenchless technology solutions includes Spiral-Wound lining and Cured-in-Place-Pipe (CIPP) technologies. These provide the highest performance and most effective solution for every rehabilitation challenge – covering all diameters, regardless of shape or pressure range.
Trenchless technologies with unique installation processes and competitive advantages
The Spiral-Wound lining method is used for the rehabilitation of gravity networks. This trenchless technology is based on the principle of spiral winding a factory manufactured continuous plastic strip into a liner of high stiffness and low weight directly into the deteriorated pipe. 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.
The trenchless CIPP method is used for the rehabilitation of water and sewer pressure. This technology is based on the principle of inverting or directly pulling a flexible liner into the deteriorated pipe. The liner material, coated with unique resins, is then hardened to form a liner with outstanding stiffness and performance characteristics. Trenchless technologies such as the Cured-in-Place-Pipe liners can accommodate bends in the pipe, and are also suitable for the rehabilitation of pressure pipes as fully structurally solutions.
Our range of trenchless technology products and services also includes the tools and equipment required for the various rehabilitation methods. The installation equipment is manufactured in-house according to American standards and is available for hire or purchase, with various financing models available.
