SPR™ PE Pipe

SPR™ PE is a trenchless, spiral-wound, steel reinforced HDPE product used to restore the reliability and integrity of aging sewers, storm sewers, and culverts in a jointless fashion without excessive site disruption.

Trenchless Pipe Lining and Sewer Repair

When dealing with a closed system storm sewer, sanitary sewer or culvert with limited access, SPR™ PE pipe rehabilitation provides a solution for restoring hydraulic efficiency, reliability and integrity to these aging systems using a spiral, machine wound and trenchless pipe renewal process.

Steel Reinforced Polyethylene for Rehabilitating Sewers, Pipes, and Culverts

The SPR™ PE pipe rehabilitation process is a solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm sewers, and culverts. SPR™ PE liners can structurally rehabilitate brick, concrete, glass reinforced plastic, or corrugated metal pipelines.

What sets SPR™ PE apart from other traditional slip-lining products is that the pipe is relined from the existing access point in a jointless fashion without excessive site disruption.

SPR™ PE is a steel reinforced plastic pipe liner with a smooth internal surface. A single strip of steel reinforced HDPE profile is progressively wound into

the existing pipeline by the SPR PE machine that is positioned in the base of the access chamber. The edges of the profile are welded together by the SPR PE machine, forming a continuous watertight liner. With this technology, Contech can manufacture a new pipe inside the host pipe with equipment that fits through a 22” manhole opening. SPR™ PE is the optimal solution for structural lining in closed system storm and sanitary sewers and culverts with limited access.

The liner is introduced into the host pipe at a fixed diameter, and annular space is subsequently grouted using a cellular or low strength cementitious grout. The plastic profile that forms the liner is reinforced with steel that is fully encapsulated within the HDPE material. The steel reinforcement is selected based on the individual project design requirements.
