Cured-In-Place Pipe (CIPP)

Extending the life and integrity of mains and structures

Cured-in-place pipe lining, often referred to as CIPP, is an established, yet still evolving technique. Once suitable for rehabilitating sanitary and storm sewer mainlines, laterals and culvert pipes, our lining process is also available for use in pressure, force main and potable water pipes.

CIPP is a proven method to successfully rehabilitate underground infrastructure, costing 20 to 40 percent less than open trench replacement. This rehabilitation method saves money by trenchlessly renewing the host pipe lining while preventing costly breaks, minimizing future repairs and maintenance.

Cured-in-place pipe liner can be used on pipes with diameters from 6 inches to more than 9 feet. In fact, this method is as versatile as it is reliable. We can use it for short-liner repairs of just a few feet up to large-scale system repair installation lengths of more than 2,000 feet. The result is a fully structural pipe relining within the existing pipe with an additional 50 years added to its design life.

CIPP rehabilitation begins when custom-designed liners are impregnated with resin at one of our regional wet-out facilities. For larger diameter pipes, wet-out can be achieved on the jobsite in a temporary facility. Liners are inserted into the pipe through a utility manhole, using air, water or pulleys. Depending on the type of liner, its location and its size, we can use water, steam or ultraviolet light for curing.

Utilizing specifically engineered CIPP technology for drinking water, Michels is also a certified NordiTube installer. CIPP pipe lining is NSF 61-approved for potable water systems and deliver a structural solution for rehabilitation of water mains. All pipes are designed to meet the AWWA Class IV guidelines.

Benefits of Cured-In-Place Pipe Rehabilitation:

• Used for rehabilitating sanitary and storm sewer mains, water mains, culverts and other pressure pipes
• Reduces cost of disruption of municipal infrastructure - roadways and sidewalks
• Short duration of project time
• Polyester felt tubes provided by ISO 9001-certified, experienced manufacturers
• Experience gained from more than 6 million feet of cured in place pipe lining installation in the U.S. and internationally
• Ability to self-perform bypass operations resulting in a turnkey solution

Michels has more than 6 million feet of experience in industrial and municipal cured in place pipe rehabilitation applications. We tailor our service to each application by choosing specialized resin that best fits the project's demands. Our vast experience helps us navigate challenging time and space constraints while creating a one-of-a-kind solution for each project.
