ENGINEERED SOLUTIONS SPR™ PE Steel Reinforced Liner Reline Done Right™ PIPE SOLUTION

Contech is your single source for rehabilitation of sanitary & storm sewers, culverts and bridges. ® Contech Engineered Solutions has partnered with SEKISUI Rib Loc Australia to offer the most technologically advanced, environmentally friendly, trenchless solutions for small to large diameter pipe renewal. SPR™ PE offers a fully structural solution using a spiral, machine wound, trenchless pipe renewal process. This technology can be utilized in a range of sizes (29” - 118”+) for circular applications. SPR™ PE is a spiral wound, steel reinforced HDPE product that is fusion-welded to form a...

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...

Structural liner, strong and lightweight Manufactured from pipe grade HDPE with embedded steel reinforcing Steel thickness can be varied to vary pipeline stiffness Liner diameters from 29 to 118 inches using six standard profiles Suitable for gravity flow sanitary sewer and storm water pipelines High chemical resistance Industrial applications Improved flow with smooth HDPE material (Manning’s n of 0.010) Installation can occur with up to 25% of the flow present Flow Advantages • Hydraulically efficient, smooth bore with circular cross section • Usually greater hydraulic capacity than the...

PART 1 - GENERAL 1.1 SECTION INCLUDES A. Materials and procedures for fixed diameter machine spiral wound high density polyethylene (HDPE) pipe liner with fully encapsulated steel reinforcing. 1.2 SUMMARY A. Machine spiral wound steel reinforced HDPE liner is intended for use in the rehabilitation of sanitary and storm sewers without excavation. The lining process uses a continuous one piece HDPE profile strip reinforced with a fully encapsulated continuous profiled steel strips for increased liner stiffness. The profile strip is machine wound directly into the deteriorated pipeline from an...

SPR™ PE in Action Installation Site Lakehurst Naval Air Station - Reline Lakehurst, New Jersey Materials • SPR™ PE Structural Lining • 786 LF for 48” dia. RCP • 703 LF for 54” dia. RCP Project Details A number of reinforced concrete pipe (RCP) runs used to carry stormwater had deteriorated and were no longer hydraulically or structurally sufficient. The pipes needed to be replaced or repaired. The main challenges for this particular project were the extremely tight constraints and the narrow construction activity windows. After a discussion with Contech Engineered Solutions, the facilities...
