InsituGuard™  Pressure Pipe 

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 InsituGuard™ – the non-disruptive, HDPE solution for pipe rehabilitation which includes the InsituFold™ and InsituFlex™ processes.

InsituFlex™ and InsituFold™ are solutions for your pressurized pipe system:
• Normal diametre ranges from 100 to 1200 mm 
• Produces a continuous, tight-fitting structural or semi-structural solution
• Pressure rating to 10+ bar
• Rapid installation
• Drinking water approved
• Negotiates bends up to 22.5 degrees
• Utilizes high-performance PE 100
• Minimizes disruption

InsituFlex™ and InsituFold™ are ideal for rehabilitation of transmission and distribution water mains of up to 1200 mm in diametre. The polyethylene liner isolates the flow stream from the host pipe wall, eliminating internal corrosion. The InsituFlex™ System and InsituFold™ System place the PE 100 liner in radial contact with the inside of the host pipe. Inserted into a new or existing pipeline by our proprietary installation processes, the polyethylene liner is continuous, and installed tightly against the inner wall of the host pipe. Our solutions typically do not reduce flow capacity, unlike other rehabilitation methods, which produce larger annular spaces between the liner and host pipe.
