The SPR™ EX lining system is a unique process for restoring the efficiency, reliability and structural integrity of aging sewers, stormdrains and culverts. SPR™ EX liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sewer and stormwater pipelines with diameters from 6'' to 42''. 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.
