The SPR™ RO pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts. The system consists of a single strip of PVC profile which is progressively wound into the existing pipeline by the SPR™ RO machine. The edges of the profile are interlocked by the SPR™ RO machine as it moves inside the deteriorated pipeline, forming a continuous watertight liner. The winding machine can alter diameter as it traverses the pipeline to produce a liner of optimal diameter. SPR™ RO liners can structurally rehabilitate brick, concrete, glass reinforced plastic or corrugated metal sewer and storm water pipelines with diameters from 32'' to 72''.
