800 mm – 5500 mm Pipe Lining
Round & Non-Round Shapes
100% Trenchless
Large Diameter Trenchless Pipe Renewal
SPR™ spiral‐wound pipe method offers tailor‐made solutions for the rehabilitation of gravity pipes in the nominal diameters DN800 to DN5500 and can be used for any host pipe cross sections and conditions. SPR™ is designed for installation in live flow conditions.
SPR™ Trenchless Lining Process
SPR™ Lining Process
SPR™ utilizes steel reinforced interlocking PVC Profile strips, which are formed into a liner using a winding machine. The annulus between liner and host pipe will be grouted with a high performance grout, resulting in a high‐quality concrete pipe with an inner and highly resistant lining.
Various profile types are available to meet a wide range of rehabilitation requirements. They can also be used to rehabilitate bends up to 5D.
