Reline and Rehabilitation Solutions

As our infrastructure ages, the roadway, water management and sewer control systems are deteriorating and losing integrity. Also, changing service conditions affect once competent structures so that they may no longer meet load or traffic requirements. 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. Reline Done Right™

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:

  • Geometric shape and condition of existing pipeline or structure (and access structure)
  • Hydraulic requirements and limitations
  • Optimum shape, size and materials
  • Constructability
  • Design service life
  • Structural analysis and design
  • Specification goals
