SPR™

LARGE DIAMETER TRENCHLESS PIPE RENEWAL

SPR™ is a trenchless spiral wound technology for the rehabilitation of sewers, storm drains and culverts for large diameters between 32" - 217". The process consists of feeding PVC profile through existing access points and winding the profile at a fixed diameter within the host pipe to form the liner. High compressive strength grout is then injected into any annular space to reinforce the structural integrity of the liner. SPR™ is capable of rehabilitating non-circular and custom shape pipelines.
