As our infrastructure ages, the roadway, water management and sewer control systems are deteriorating and losing integrity. Maintaining these critical structures is a major challenge. Today, perhaps more than ever, keeping our infrastructure safe and workable with limited financial resources requires innovative solutions. Replacement can be costly and time consuming. Contech makes it easy. We make it our business to know the ideal solution for you - inside and out.

Rehabilitating or relining a drainage or sanitary pipeline or culverts requires a site-specific analysis. There is no one-size-fits-all approach. Every reline project needs to be examined closely by qualified professionals.
From an engineering perspective, the design approach must take into account the usual design parameters and must carefully evaluate the current condition of the pipe or structure and the supporting fill that surrounds it. The primary areas where an engineer should be concerned are:
| SPAN RANGE | PRODUCT | DESCRIPTION | |
|
DRAINAGE
|
12” – 36” | A2™ Liner | PVC corrugated pipe with smooth interior wall |
| 18” – 102” | ULTRA FLO® | Spiral rib aluminum, aluminized and polymer coated steel pipe | |
| 12” – 144” | HEL-COR® & CORLIX® | Corrugated aluminized and polymer coated steel and aluminum alloy helical pipe | |
| 30” – 120” | DuroMaxx® | Steel reinforced polyethylene pipe | |
|
SEWER
|
12” – 36” | A2™ Liner | PVC corrugated pipe with smooth interior wall |
| 30” – 120” | DuroMaxx® | Steel reinforced polyethylene pipe | |
|
STRUCTURES
|
4’ – 20’+ | TLP | Steel and aluminum 2- flanged liner plate |
| 5’ – 23’+ | ALSP MULTI-PLATE® |
Aluminum structural plate Galvanized steel structural plate |
|
| 8’-9” – 35’-5” | ALBC | Aluminum box culvert | |
| 19’-5” – 65’ | SUPER SPAN™ SUPER-PLATE® BridgeCor® |
Galvanized steel structural plate long spans Aluminum structural plate long spans Deep corrugation galvanized steel structural plate |
|
| 12’ – 102’ | CON/SPAN® and BEBO® | Precast concrete arches |
Rehabilitate failing structures and eliminate the time, cost and safety problems of complete replacement with our systems. Contech's portfolio includes a full array of reline products for culverts, sanitary and storm sewers.
Designed with a smooth inner wall for outstanding hydraulic capacity, DuroMaxx® pipe provides the properties necessary for long-term service and performance in the most demanding environments.
Lining inadequate or failing structures with corrugated metal material or plastic pipe uses little of the available area, thereby preserving the maximum amount of the original opening. Due to the hydraulic efficiency of Contech products, often a smaller structure provides the same hydraulic capacity as the original because of the low Manning “n” factors of A-2000™ and A2™ Liner PVC pipes and HEL-COR® and ULTRA FLO® CMP. Existing culverts and arches are generally lined with structures of the same shape, though slightly smaller in size. Rectangular openings can be lined with round, elliptical or pipe arch structures. Corrugated metal structures can fit almost any existing shape.
Reline drainage structures with hydraulically efficient CORLIX® or A2™ Liner pipe. DuroMaxx® SRPE, ULTRA FLO® and HEL-COR® are available in standard diameters through 120” (custom up to 144" for HEL-COR®). Special diameters are also available in both products. The PVC pipe systems, A-2000™ and A2™ Liner Pipe — used for both drainage structures and sanitary sewers—are available through 36” diameter.
