Invert-A-PipeĀ®

IPR has vertically integrated its pipeline rehabilitation process with its Invert-A-Pipe product. IPR can manufacture CIPP liners from 6" to 120" in diameter. In addition, it has six wet out facilities strategically located throughout the nation. This allows IPR to independently manufacture, resin impregnate, and install CIPP liner. Invert-A-Pipe meets all requirements outlined in ASTM F-1216 and D-5813 as well as being ISO 9001 certified.

Installation

The Cured In Place Pipe lining system for gravity-flow sewers and culverts is the most proven trenchless pipeline rehabilitation process in the industry. CIPP is a resin-saturated felt tube that is inverted and cured in a deteriorated pipe. It is a cost-effective way to extend the design life of water and sewer infrastructure without decreasing capacity. 

CIPP Projects

As the largest privately held trenchless rehabilitation contractor in the nation, IPR is committed to operational excellence and customer support. IPR's CIPP liners meet all the testing requirements for an expected design life of 50 years consistent with our Quality Management System (QMS). 

Latest Projects

CIPP is the most widely specified trenchless rehabilitation solution and is considered the most cost-effective method for extending the design life of deteriorated pipe infrastructure. The application is ideal for sanitary, storm, and pressure applications. IPR has six wetout facilities strategically located throughout the nation to support its clients. Using the Invert-A-Pipe® product, IPR has the capabilities and experience to install CIPP liners ranging in diameter from 6 inches to 144 inches.

The CIPP process begins with the resin impregnation of the felt liners at a wet-out facility. The resin mixture is injected into the liner using a stinger creating a resin slug on one end of the liner. The liner is then fed through a pinch roller while a vacuum hose is attached at the other end to remove air pockets. This ensures that the resin fully saturates the liner before it is loaded into a refrigerated box truck. Once the liner is completely wet out, it is transported to the installation site.

At the installation site, the liner is attached to the shooter and inverted into a manhole using air or water pressure. Once the liner is fully inverted, the curing process begins by circulating hot water or steam into the liner. The heat from the curing process activates the resins and hardens the liner creating a new pipe within the host and extending the design life by 50 years. The services are then reinstated using robotically operated cutting equipment. 

IPR offers two CIPP repair solutions for all types of pipes. For standard installations, we recommend our Isophthalic resin-based liner technology system. For stricter requirements and harsher environments, we offer an advanced lining system featuring eco-friendly epoxy resins. With millions of feet installed worldwide, our system delivers a non-invasive and permanent solution that minimizes downtime and maximizes cost savings.

CIPP Advantages:
• Minimizes environmental impact and surface disruption
• Restores or improves the host pipe’s structural characteristics 
• Excellent corrosion resistance 
• Improved hydraulic flow capacity
