Non-disruptive, polyethylene pressure pipe rehabilitation systems

Much of the world’s drinking water pipe infrastructure is long past its design life and in need of repair. Complete replacement of these pipes using conventional dig solutions can be time consuming and very disruptive to traffic, citizens and the environment. These problems can easily be avoided by choosing PolyFlex™ and PolyFold™ – the non-disruptive, PE solutions for pipe rehabilitation.

PolyFlex™ and PolyFold® are ideal for your pressurized pipe system:
• Normal diameter ranges from 4 inches to 48 inches
• Produces a continuous, tight-fitting structural or interactive solution
• Pressure rating to 150+ psi
• Rapid installation
• Drinking water approved
• Negotiates sweeping bends 
• Utilizes high-performance PE 100 (4710)
• Minimizes disruption

PolyFlex™ and PolyFold® are ideal for rehabilitation of distribution and transmission water mains of up to 48 inches in diameter. The polyethylene liner isolates the flow stream from the host pipe wall, eliminating internal corrosion.  Inserted into a new or existing pipeline by our proprietary installation processes, the polyethylene liner is continuous, and installed with a close-fit against the inner wall of the host pipe. Our solutions typically do not reduce flow capacity, unlike other pipe rehabilitation methods, which produce larger annular spaces between the liner and host pipe.
