SPR™TF/RO Spiral Wound Lining
40″ – 60″ Pipe Lining
No Grout Solution
100% Trenchless
SPR™TF/RO PVC Liner
40" - 60" Pipe Lining
No Grout Solution
100% Trenchless
Tight Fit PVC Lining
SPR™TF is a Spiral Wound pipe rehabilitation method for mid-range diameter sewers, storm drains and culverts. This trenchless lining system ‘lays’ PVC liner directly against the host pipe wall, requiring no annular space grouting.
SPR™TF is our newest innovation in Spiral Wound Lining. The SPR™TF method features 2 different winding machines depending on the project; a lightweight, compact machine or one featuring rotating hydraulic arms. Both machines traverse the pipeline while constructing a tight-fit liner.

SPR™TF/RO Lining Process
The trenchless pipe lining process begins by feeding PVC profile from an above ground spool directly into the host pipe. SPR™TF traverses the length of a deteriorated pipeline while pulling profile to construct the PVC liner. Wraps of PVC are locked together as the winding machine continues down the pipeline.
The machine ‘lays’ profile directly against the pipe wall, resulting in no space between liner and pipe. Since the profile is installed directly against the pipe wall, no annular space grouting is required. The fully structural pipe rehabilitation process is complete once the liner reaches the far end manhole and the ends are sealed.

Trenchless Lining Methods
3 Spiral Wound installation methods based upon pipe diameter
SPR™EX is a tight-fit liner suitable for small-diameter sewers, storm drains, and culverts. It does not require annular space grouting.
The PVC profile is wound directly into the host pipe by the hydraulic winding machine in the access chamber.
SPR™TF/RO is a trenchless pipeline rehabilitation method for mid-range diameter sewers, storm drains, and culverts that does not require annular space grouting.
This method uses two different winding machines that traverse the pipeline while constructing a tight-fit liner.
SPR™ is used to repair large round and non-round sewers, storm drains, and culverts.
The PVC profile is wound into the pipe by a traverse winding machine, and then grout fills the annular space.
