Types of Sewer Linings for a Cracked Pipe
Without totally replacing your sewer lines or destroying the land nearby, sewer linings can assist in repairing cracked pipes.
Consider your alternatives before replacing an existing underground sewer pipe that has started to leak. It might not be necessary to replace the sewer pipe entirely. Relining your current pipes is often a better choice. Total sewer excavation can result in significant collateral damage (and expense) to the neighborhood if your sewer lines lie underneath trees, close to lush landscaping, walkways, driveways, or other semi-permanent features.
Sewer Line Replacement is Expensive and Complex
Pipe relining is often a fantastic alternative to replacing your sewer lines. There are four different types of pipe relining systems that can be used to do the task. Your pipes’ interiors can all be repaired using the available materials, saving you from having to replace your pipes entirely.
Current pipe relining systems come in the following varieties:
- Cured-in Place
Trenchless relining systems can be repaired using cured-in-place pipework. Without having to dig a trench, expert sewage and drain companies can remotely line the cracked pipe portion. The contractors will apply the lining to the problem area after thoroughly cleaning and drying the pipe’s interior. Hot steam jets are used to hold the liner in place while it molds into all of the pipe’s cracks.
- Pull-in Place
The ideal lining technique for pipelines with bigger gaps and cracks is pull-in place. Heat, such as steam, is used to fix the material inside the pipe. The lining is then pulled into position using epoxy (the place being the area of the pipe that needs repair).
Two access points are required to pull the liner through the desired location: one to feed the liner and one to pull it through. The sleeve is spread open in the pipe and held against the inside walls of the pipe as it dries.
- Pipe Bursting
The pipe-bursting technique is applied to pipelines that have sustained major damage, to replace a complete pipe network, or to repair longer stretches of sewer pipeline. Two four-foot square access pits at either end of the pipeline are required for the installers to have physical access to the pipe in order to start the repair.
At the access point on one end of the pipe, the installers start by positioning a “bursting head.” The head is pulled through the pipe by hydraulic force. As it moves through the system, it rips apart the old pipe and pulls in a brand-new seamless pipe behind it. The pipe is made of plastic and can withstand root intrusions for up to 100 years.
- Internal Pipe Coating
An existing sewer pipe that has started to leak into the surrounding soil can be repaired by qualified installers using an internal pipe coating. They will thoroughly drain the pipes to get rid of any water to prepare the area for fixing. Your pipes’ interiors are coated with a thick layer of epoxy to permanently seal any leaks or breaks throughout the pipeline.
All these methods of pipe relining leave behind a seamless, smooth pipe that is built to stay for many generations. If you have additional questions, reach out to a local plumber for an on-site inspection of your property.
