Product catalog summary
Introduction
Contech Engineered Solutions, in partnership with SEKISUI Rib Loc Australia, offers the SPR™ PE system for trenchless pipe renewal. This system is designed for circular pipes with diameters ranging from 29” to 118” and uses a spiral wound, steel-reinforced HDPE liner for structural rehabilitation of aging sewers, storm drains, and culverts.
Specifications
The SPR™ PE system is a machine spiral wound HDPE liner reinforced with steel, suitable for non-excavation rehabilitation of sanitary and storm sewers. It is designed for pipes from 36 to 132 inches in diameter, forming a composite structural liner by winding a continuous HDPE profile strip with encapsulated steel strips.
Installation Procedure
The installation involves clearing debris from the host pipeline, inspecting it, and using a winding machine to form the liner within the existing pipe. This minimally disruptive process requires no excavation or bypass pumping and can be performed in live flow conditions. The annular space between the liner and host pipe is filled with cementitious grout.
Design and Material Standards
The SPR™ PE system complies with industry standards such as ASTM F 1741 and Australian Water Authority Specifications. The HDPE material meets ASTM D 3350 standards, ensuring high chemical resistance and structural integrity.
Advantages
The system offers a smooth internal surface for improved hydraulic efficiency, structural flexibility, and environmental safety. It is designed to withstand challenging site conditions and provides a strong, standalone liner that does not rely on grout for structural support.
Project Examples
Lakehurst Naval Air Station, New Jersey: SPR™ PE was used to reline deteriorated reinforced concrete pipes, avoiding disruptions to aircraft operations.
South Kansas River Pump Station, Topeka, Kansas: The system was chosen for its cost-effectiveness and minimal disruption during the rehabilitation of a sanitary sewer line.
Conclusion
The SPR™ PE system is a proven, efficient solution for pipe rehabilitation, offering structural integrity, minimal site disruption, and compliance with industry standards.
SPR™ PE Technology
SPR™ PE is a relining technology that allows for complete system relining from a single access point, such as a 22-inch manhole, even under live flow conditions, providing a significant advantage over other technologies.
Engineered Solutions
Contech offers a range of engineered solutions designed for durability, hydraulics, corrosion resistance, and stiffness, including Corrugated Metal Pipe (CMP), Steel Reinforced Polyethylene (SRPE), High Density Polyethylene (HDPE), and Polyvinyl Chloride (PVC).
Stormwater Solutions
Contech provides solutions for stormwater management in land development projects, including Stormwater Treatment, Detention/Infiltration, Rainwater Harvesting, and Biofiltration/Bioretention.
Structural Solutions
Innovative options and support for crossings, culverts, and bridges are offered, such as Plate, Precast & Truss bridges, Hard Armor, Retaining Walls, and Tunnel Liner Plate.

SPR™ PE World Wide Project Experience Fast Installation with Small Construction Footprint SPR™ PE (known as Ribline in other parts of the world) has been used to rehabilitate gravity pipelines since 2005. What sets SPR™ PE apart from other traditional slip lining products is that the pipe is relined from the existing access point in a jointless fashion without excessive site disruption thanks to the ability to place equipment and profile through normal manhole castings. SPR™ PE is a proven technology and has been installed under difficult site conditions with minimal disruption to the public....
