Lining Systems: Rehab Spotlight

April 2013, Vol. 68 No. 4

The Danby Pipe Renovation System is a Grouted-in-Place Liner that produces a renovated pipe that 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 an 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. The Danby system is used for man-entry pipes for rehabilitating 36 inch and larger pipes in circular and non-circular sewers and culverts. 281.598.1126,


Ultraliner PVC Alloy Pipeliner is ideal for gravity and low pressure wastewater or storm sewers and culverts. Specifically engineered for use in trenchless applications providing ASTM F 1871 and F 1504 industry standard pipeliners, PVC Alloy is pre-manufactured under tight quality controls and is environmentally friendly – no styrene! The PVC Alloy material can be "thermoformed" at steam temperatures, enabling Hydroliner PVC Alloy Pipeliner to essentially "blow-mold" to the conformation of the host pipe including size transitions, tight bends, offset joints, and other irregularities. 256.831.5515,
