Spiral Wound Lining

Versatile Pipe Restoration Techniques

Suited for a wide range of diameters and shapes, Spiral Wound Lining installs a new pipe inside of an existing structure that allows for the extension of a system’s service life or sealing the structure. These liners are generally used to rehabilitate gravity pipeline applications, such as storm sewers, sanitary sewers, conduits, culverts, and process pipes.

In the Spiral Wound Lining system, the rotational action advances the liner through the host pipe. The continuous spiral joint is watertight. Once the liner is in, be it a standalone pipe or simply a liner, it is grouted in place.

Benefits of Spiral Wound Lining:

• Versatile, innovative method
• Installation can be carried out without interrupting service (depending on flow volumes)
• Generates little to no noise or air pollution
• Minimal traffic disruption
• Provides short project periods, but long-term success
