The Danby Pipe Renovation System is a Grout-in-Place spiral wound PVC liner that produces a renovated pipe which is a layered composite of PVC Liner, cementious grout, and the original pipe. The combination of the ribbed profile on the PVC liner and the highly fluid nature of the grout produce a highly integrated structure with the PVC liner "tied" to the original pipe through the grout which, in addition, provides some direct repair of the old pipe.

  • Danby can be used for man-entry pipes that are 36" and greater.

  • The PVC material is manually lowered into the pipe through existing manholes, no need for costly access pits

  • Spiral wound Danby can also be installed in round, egg shape, semi-elliptical, horseshoe, and manholes.

  • Extended life by combining cementitious grout for structural integrity and the PVC liner for a new corrosion resistant pipe surface.



Our modular system works in similar fashion as Spiral wound, the combination of the PVC liner and the cementitious grout provides failing structures a new corrosion resistent surface with structural backing to extend the life of a lift station for over 50 years.   The modular system is able to conform to a variety of shapes and sizes.

Modular system can be installed in:

  • Wet Wells
  • Lift Stations

  • Junction Boxes

  • Clarifiers

  • Flow Splitter Boxes

  • Aeration Basins

  • Or any type of structure

Danby, LLC has created a name for itself with its proven rehab method using the Danby Pipe Renovation grout-in-place liner, but Danby is not just for pipe rehab anymore, it’s also being used in new construction.  Manhole lids can also be precast using Danby to protect the inside of the structure.  Danby liner is also being used in new construction of Waste Water Treatment plants. Why wait until you have deterioration, be proactive and use Danby as a corrosion resistant method to protect and prevent deterioration before it starts.
