Fully Structural PVC Liners
Spiral Wound is a trenchless pipe lining method for sewers, storm drains and culverts. Our pipe liners provide fully structural rehabilitation using mechanically wound PVC.
The Spiral Wound process is 100% mechanical and can be installed in live flow. Pipe liners are constructed directly onsite using only existing access points, such as a standard manhole. This method meets design standards such as ASTM 1741-18 and ASTM 1697-18; specifying the proper installation of mechanically and machine wound PVC profiles.

There are 3 methods of installation for Spiral Wound pipe rehabilitation. Each method serves a range of pipe diameters spanning from 6″ to over 200″.

Spiral Wound Lining Process
A spool above ground feeds the PVC profile strip through existing access points. No further site excavation is necessary.
The winding machine forms the liner directly inside the sewer, storm drain or culvert. Liner is either pushed (as seen in image) down the pipeline or pulled using a traversing machine. The method used depends upon host pipe diameter.
The profile edges are locked during winding, creating a water-tight seal. The pipe liner is either installed as a tight-fit (SPR™EX & SPR™TF) or requires annular space grouting (SPR™) to finish the installation process.
Little/No Bypass
Our trenchless pipe liners are successfully installed in live flow conditions, which saves on construction costs.
Spiral Wound Liners can operate typically with around 25%-30% flow in pipe.
The Spiral Wound Lining Process
A spool above ground feeds a continuous strip of PVC strip through existing access points, such as a manhole.
The winding machine then forms the liner directly inside the sewer, storm drain or culvert. The pipe liner is either installed as a tight fight (SPR™EX & SPR™TF) or requires annular space grouting (SPR™) to finish the installation process.
