Cutting-edge tech to help you stay on top of your projects

Suited for a wide range of diameters and shapes, both Danby Grouted-in-Place Lining and Spiral Wound Lining installs a new pipe  inside of an existing structure that allows for the extension of the service life of a system or to allow the sealing of an existing structure.

Benefits of the Danby Lining:

  • Structural & Nonstructural Rehabilitation
  • Corrosion Resistant Liner
  • Stops Exfiltration and Infiltration
  • Improves Hydraulic Capacity
  • Trenchless Installation (only manhole access required)
  • Circular and Non-Circular Shapes
  • Small Installation Footprint
  • Gravity and Low Pressure Applications

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 in turn grouted in place.

Benefits of Spiral Wound Lining:

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

These  liners are generally used to rehabilitate gravity pipeline applications, such as storm sewers, sanitary sewers, conduits, culverts and process pipes.
