The SPR™PE pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts. SPR™PE is a fully structural, light-weight liner. The fully encapsulated steel reinforcement is designed to provide a liner of optimum stiffness for the application. SPR™PE liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sanitary sewer and stormwater pipelines with diameters from 900 mm to 3000 mm. SPR™PE is WRc Approved™ (PT/304/0710).
