SPR™ST Machine Wound Spiral Lining

600 mm – 3000 mm Pipe Lining

Steel-Reinforced

100% Trenchless

Steel Reinforced 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 600 mm to 3000 mm. SPR™ST is WRc Approved™ (PT/304/0710). 

SPR™ST MWSL Process

SPR™ST Lining Process

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.
