Unfortunately, sewer pipes do not last forever. After a period of time pipes made out of various materials such as cast iron, clay, galvanized steel will develop a buildup of corrosion that will often lead to cracks that tree roots will grow through in search of the water inside the sewer line. The end result? Drain backups, a nightmare for most homeowners and property managers. In many cases in the past, the only option would be to dig the damaged pipe and replace it with a new one. However, that requires a significant amount of time and disturbance to the property and often leads to destroyed floors and lawns. An alternative to digging up drain pipes is pipe lining, a no-dig trenchless solution to fix damaged sewer lines that saves landscapes, preserves the integrity of the building structure, and is time effective.
WHAT IS THE PIPE LINING PROCESS?
If a sewer line cracks due to the combination of corrosion and tree roots, the inside of the pipe will need to be cleaned and repaired. Cleaning with mechanical cutters like the Micro-Cutter will remove the buildup of corrosion and roots, therefore, ensure the epoxy liner called cured-in-place-pipe (CIPP) will adhere to the damaged sewer pipe.
Once the pipe is cleaned the two-part epoxy saturates a felt liner that is then scored (cut) on the outside of the liner so that the epoxy will adhere to the inside of the pipe. The adhesion process ensures that no water will be able to flow between the liner and the damaged host pipe. The liner is quickly pulled through the pipe and the rubber bladder inside the epoxy saturated liner is expanded to allow the epoxy to adhere and cure before the bladder is deflated and taken out of the pipe.
Once the cured-in-place-pipe CIPP liner hardens to the pipe – the liner separates the original damaged pipe that is susceptible to failure from the material flowing through it. It’s a pipe within a pipe! In addition to solving a cracked sewer line, this CIPP liner can be a structural pipe, meaning if the host pipe deteriorates your property will continue to have a serviceable sewer line with the epoxy CIPP pipe.
