Corroded pipe with epoxy lining

Cured in place pipe lining is an effective and long-term solution to most sewer problems. CIPP stands for cured-in-place pipe lining, a method of replacing damaged or deteriorating sewer pipes without digging them up. This procedure replaces damaged pipes without any major excavation, resulting in minimal disruption to businesses and neighborhoods. But how long do the results of pipe lining actually last?

How Is Trenchless Pipe Lining Done?

Trenchless pipe lining in Atlanta, GA, starts with an inspection of your sewer line. This allows us to locate the damaged pipe and determine the condition of your sewer line. An inspection also tells us how much epoxy we need to repair the pipe. When done, we clean the pipe thoroughly using hydro jetting to get rid of any debris, corrosion, and clogs. After this, a felt liner saturated with resin or epoxy is inserted into the pipe. This is done through an existing access point, usually the maintenance hole or an exit. The liner is inserted and pulled into place. 

Once the liner is in place, it is inflated with air or water. This pressure forces the cured coating of the liner against the interior of the damaged pipe and seals the cracks and leaks. Once the epoxy has cured, the next step to sewer pipe lining is to inspect the pipe and make sure that it is repaired properly.

How Long Does CIPP Lining Last?

CIPP pipe lining is an effective solution for various problems in wastewater systems and pipes. These include root intrusions, corrosion, pipe bursting, cracking, and leaking. This method of repair also improves water flow and is an excellent way to increase the lifespan of your pipes.

Professional grade epoxy typically lasts anywhere from forty to fifty years. However, the liner can last even longer, depending on the maintenance level and the environment in which it is installed. Proper maintenance is necessary for the liner’s longevity and should be done regularly. This typically includes periodic inspections and the implementation of proper cleaning techniques.
