5 Types of Sewer Linings for Cracked Pipes
Cracked sewer pipes can be more than just a costly repair - they can result in extensive and pricey property damage and lead to serious health risks. Sewer linings can help repair cracked pipes without having to completely replace your sewer lines or destroy the area around them.
If you are looking to replace an existing underground sewer pipe that has started to leak, first consider your options. A full sewer replacement may not be necessary. Often times, relining your pipes is a better and more cost-effective solution. If your underground sewer lines are beneath trees, near extensive landscaping, sidewalks, driveways, or other semi-permanent features, total sewer excavation can cause a great deal of collateral damage, not to mention expense, to the surrounding area.
In many cases commercial property owners are able to get away with just relining their pipes. There are four types of pipe relining systems to get the job done right. All the materials will rehabilitate the interior of your pipes without having to completely replace them.
Here are the types of pipe relining systems available today :
1. Cured in place pipe lining (CIPP) :
Cured in place pipe lining, also known as CIPP lining, is a method of trenchless pipe restoration used in existing pipe repair. This process is done to preserve the current pipes that have been damaged by leaks, cracks, intruding roots, and rust. It increases the lifespan of a pipe system for up to 100 years while also possibly preserving the building structures and causing little to no damage to the property.
2. Pull-in Place :
Pull-in place is the best lining method for pipes that have larger gaps and cracks. The material is fixed into the pipe using heat, like steam. The epoxy-saturated liner in then pulled into place (the place being the area of the pipe that needs repair). To pull the liner through the desired location, two access points are needed : one to feed the liner and one to pull it through. Air is introduced into the pipe to open the sleeve and hold it against the inner walls of the pipe until it dries in place.
3. Pipe Bursting :
The pipe bursting method is used on pipes that are severely damaged, for replacing an entire system, or for repairing larger sections of sewer pipeline. The installers need physical access to the pipe in order to begin repair, which includes two four foot square access pits at either end of the pipeline. The installers begin by placing a "bursting head" at the access point on the one end of the pipe. Hydraulic power is used to drag the head through the pipe. As it makes its way through the system, breaking the old pipe apart and drawing it into a new seamless pipe behind it. The pipe is a plastic material that will; be impervious to root intrusion for up to 100 years.
4. Sliplining :
Sliplining is one of the oldest methods of trenchless pipe rehabilitation of existing pipelines. It is used to repair leaks or restore structural stability to an existing pipeline. It is completed by installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends. The most common material used to slipline an existing pipe is high-density polyethylene (HDPE), but fiberglass-reinforced pipe (FRP) and PVC are also common.
5. Internal Pipe Coating :
Professional installers use internal pipe coating to repair an existing sewer pipe that has started to leak into surrounding soil. To prepare the area for treatment, they will completely drain the pipes to get rid of any water. A thick epoxy coating is sprayed on the inside of your pipes to permanently seal the leaks and cracks throughout the pipeline.
