Underground pipes are used to carry everything from sewage, water, oil, gas, and chemicals. As time passes, many pipes become old and may become weakened, damaged, or even rupture. The seams where they have been welded together often crack, causing spills, leaks, and seepage. When drain pipes break, sewage can leak into the ground, causing a disaster. For property owners, fixing these aging pipes can be extremely messy and costly. In the past, the only way to repair those broken pipes was to apply an old solution — to dig and manually replace or repair them. Fortunately, there have been major advances in trenchless pipe repair, the most effective one being cured in place pipe (CIPP).
What is CIPP?
Cured in place pipe is the latest trend in repairing or replacing underground pipes without digging a trench. CIPP is a seamless and jointless method of fixing pipes, which involves inserting an epoxy sewer liner inside the old pipe itself. It can be used to fix short amounts of pipe or larger lengths as much as 300 feet. CIPP is complicated to explain, but it is also very ingenious, and can be done with very little to no excavation at all. In Scottsdale, sewer epoxy lining cured in place pipe is being installed regularly by Legendary Home Services.
The CIPP Process
The initial step of cured in place pipe involves the insertion of a bendable, epoxy resin saturated liner into the old or currently existing pipe. The liner is in the shape of a long and bendable tube or elongated sock. The epoxy is made up of two elements, a base and a catalyst. After those are mixed, the epoxy is activated and the curing of the liner begins. The liner is time sensitive and must be placed inside the pipe within four hours of its manufacture or the resin will be ineffective. Once the polyester liner is inside the pipe, hot air or hot water pressure is applied. This will expand the liner until it fits snugly and neatly against the inside walls of the old pipe. There should be no air pockets or impediments between the outer surface of the liner and the inside of the pipe. The fit must be airtight so that a pipe within a pipe has just been created.
The next step in the process is inspection. There should be nothing stopping the liner from completely sealing itself against the inner pipe walls. Rocks, dirt, air, or roots must be removed for the CIPP to work. Inspection is done by sending a closed circuit television camera (CCTV) into the pipe where people on the surface can view it. If the camera picks up any objects breaking the seal, they will have to be removed.
Benefits of CIPP
If done properly, CIPP actually increases the flow capacity of the old pipes by reducing friction. It requires little digging, if any, because entry to the pipe is usually gained through a cleanout or manhole. CIPP saves the property owners energy, time, manpower, and a lot of money. CIPP can be applied to pipes of all sizes and shapes resulting in a seamless pipe that is better than before. The liners have a 50-year warranty, which is the same lifespan as a brand new pipe.
