SPR™ EX

STRUCTURAL, LIGHT WEIGHT, CLOSE FIT LINER FOR GRAVITY PIPELINES

SPR™ EX is a trenchless spiral wound technology for rehabilitating sewers, storm drains and culverts between 8" - 42" in diameter. The system consists of a single strip of PVC profile which is progressively wound into the existing pipeline by the SPR™ EX machine. The static winding machine spirally winds the PVC profile into the deteriorated pipeline at a smaller diameter than the host pipe. During this process, the liner expands once the cutting wire is pulled within the interlocking profile. This expansion creates a water tight fit to the host pipe wall.
