Rehab Product Focus: Sliplining

NEWLINER Culvert Pipe from Advanced Drainage Systems Inc. (ADS) is a high-density polyethylene (HDPE) pipe, with smooth outer and inner walls, designed specifically for relining underground culverts. The corrosion- and abrasion-resistant HDPE handles a pH range from 1.25 to 14. Available in diameters from 12 to 72 inches, it comes in 16.5-foot sections with threaded, soil-tight joints that allow it to be pushed or pulled into existing structures at longer lengths, compared to pipe with bell and spigot joints.

HOBAS pipe slipliningHobas Pipe USA
Hobas CCFRPM pipe is ideal for sliplining because of its high strength-to-weight ratio and smooth surface. Superior hydraulic characteristics provide maximum flow recovery. Most U.S. cities have used Hobas pipe in new construction and rehab for critical installations, including storm and sanitary sewers and other corrosive environments. Contractors prefer its leak-free, push-together joints and standard 20-foot pipe sections that reduce installation time and costs.

Contech slipliningContech Engineered Solutions
Strength Reinforced Polyethylene (SRPE) is a fully structural, internally wound, steel-reinforced liner for closed-system storm and sanitary sewers or culverts with limited access. An ideal combination of materials – 80 ksi steel reinforcing and pressure-rated high-density polyethylene (HDPE) resin – results in an extraordinarily strong and durable pipe. SRPE restores hydraulic efficiency, reliability and integrity of aging sewers and storm drains, often not requiring bypass pumping during installation.
