Lining Systems: Rehab Spotlight

April 2013, Vol. 68 No. 4

Danby
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, danbyrehab.com

FOLDED PIPE

Hydroliner
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, hydroliner.com

SPIRALLY WOUND PIPE

SWP-Systems GmbH
Made is Germany and available in the United States, SWP Spirally wound pipe is made of helical plastic pipes that are manufactured in ducts and driven to the next duct in a spiral manner. Different pipe diameters can be achieved in one working cycle for pipe diameter from 250 mm (10 inches) to 600 mm (24 inches). Best of all, the SWP pipe system does not require grouting. 276.732.4932, swp-systems.de

Sekisui SPR Americas
SPR is a spiral-wound trenchless pipeline renewal process designed for use in medium to large-diameter pipelines, typically 18 inches and larger. SPR can be used in man entry and non-man entry applications. SPR utilizes steel-reinforced interlocking PVC profile strips grouted in place with an engineered specified cementitious grout. The installation equipment can be utilized via standard access points without site excavation. SPR can also be installed in vertical applications such as wet wells, access shafts and other large-diameter structures. 866.627.7772, sekisui-spr.com
