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.
For bridge replacement or Design Build projects, our Precast bridge systems can substantially reduce design and construction time, improve safety and ensure quality components for long-term performance.
Plate structures allow highway agencies and municipalities to dramatically reduce construction time and traffic disruptions when replacing our nation’s aging infrastructure. Plate bridges are ideally suited for emergency bridge replacements.
Pre-engineered Truss structures provide fast-track solutions for bridge replacement projects with quick installation – saving both time and money. These prefabricated truss structures are often installed in just one to three days.

Project Design Worksheets
Rehabilitating or relining a drainage or sanitary pipeline or structure 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:
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 corrugated steel, aluminum or PVC pipe. ULTRA FLO® and HEL-COR® are available in standard diameters through 120” and 144" respectively. 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.
When dealing with a closed system storm sewer, sanitary sewer or culvert with limited access, SPR™ PE pipe rehabilitation provides a solution for restoring hydraulic efficiency, reliability and integrity to these aging systems using a spiral, machine wound and trenchless pipe renewal process.
