NASA Cured in Place Pipe Repair


Over the past few years, cured in place pipe repair has become the preferred method of pipe repair. The latest innovation, also known as trenchless pipe repair is used to fix deteriorated pipes using minimal disorder to the environment.

Simply put, cured in place pipe lining is one of the most efficient ways to get the job done. The trenchless technology requires no excavation since usually the liner can be pushed in through a manhole or any other access point. A camera is used to view the inside of the pipe, a process simply called video pipe inspection.

One of our teams most recent jobs was a cured in place pipe repair at NASA. Cloud 9 Services joined Picote Solutions and Perma Liner for this project.

The repair at the National Aeronautics and Space Administration consisted of lining a 40 year old pipe that was 8”x150.

The first thing we did on site was to inspect the pipe. Our team used video pipe inspection to fully inspect the inside of the pipe. With this latest technology, we are able to pinpoint the root of the problem. It is an accurate and an up close and personal look into anything and everything that can be damaging the pipe- from cracks, root intrusion, debris, we are able to see it all. Once we determine the location and type of damage the liner is inverted using air or water pressure.

Once this step is complete, we access the pipe through a manhole or excavation and insert the epoxy resin felt tube. The liner is then filled with pressure, enough to make it shoot into the system. Upon completion, the pipe will be inspected via video once again. This step is done to ensure the hardening process is complete all throughout the system.

Next, the hardening process begins- we place enough pressure for the resin to harden and later forming a new jointless pipe. This forms what we call a “pipe inside of a pipe”. The new pipe is much stronger and durable. The new pipe also has the ability to last up to 100 years.
