SPR™ ST

A steel reinforced ad flexible liner

The SPR™ ST pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts. Where required for greater stiffness, the liner can be reinforced by simultaneously winding a profiled strip of steel under the tees of the PVC profile.

SPR™ ST liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sanitary and storm water pipelines with diameters from 450 mm to over 2500 mm. The plastic profile that forms the liner is provided in a range of sizes and thicknesses. The appropriate profile is
selected to provide a liner with sufficient stiffness to meet the design requirements for the project. Profiles may be reinforced with steel for high loading applications, maximizing liner stiffness whilst minimizing loss of cross section.

Project experience
SPR™ ST has been used to rehabilitate sewers, stormwater lines and culverts around the world. It has proven capable of providing a structural liner for severely deteriorated pipelines, and has been installed under difficult site conditions with minimal community disruption.
