SPIRAL WOUND PIPE LINERS SPR™ 32" - 200"+ Pipeline Rehabilitation
■The SPR™ Spiral Wound process is a trenchless rehabilitation solution for restoring the hydraulic efficiency, reliability and integrity of aging sewers, storm drains and culverts.
■The process consists of a single strip of PVC profile which is progressively wound into the host pipe through an existing manhole or access chamber. The SPR™ winding equipment traverses the length of the pipeline while constucting the liner. A spool above ground feeds PVC profile into the winding machine where the liner is wound inside the host pipe at a smaller diameter. The annular space between the host pipe wall and liner is grouted to ensure structural stability.
