Few Different Types of Sewer Lining Meant for Old Piping System

A new technology is under use for the last decade where sewer linings with cracked pipes can be repaired without completely replacing your sewer lines or by digging or destroying the surrounding area.

Now, if you want to replace your existing underground sewer pipes, which have started leaking, you can consider this Wilco Relining option.

Often, relining the existing pipes is a much better option. If your sewer lines happen to be under the trees, sidewalks, near extensive landscaping, driveways, or any other semi-permanent features, then total sewer excavation will cause major collateral damage to your surrounding area.

In a few cases, pipe relining is also considered a great alternative to the replacement of your sewer pipes. Here are a few different types of pipe relining systems that are available today:

  1. Pull-in place

If your pipes have larger cracks and gaps then pull-in place is the perfect lining method. The material will be fixed into the pipe by using heat. Then epoxy-saturated liner is pulled into the place on the area where your pipe needs repair.

For pulling the liner through your desired location, 2 access points will be needed:

  1. The first one to feed the liner
  2. The second to pull it through.

Air is then introduced into the pipe for opening the sleeve and then holds it against your inner walls of the pipe till it gets dried up.

2. Internal pipe coating

If the existing sewer pipe has started leaking into the surrounding soil then professional installers will suggest using internal pipe coating for the repair. For preparing the area for the necessary treatment, they will first completely drain out the pipes to completely get rid of the total water.

A thick epoxy coating will then be sprayed on the inside of the pipes for permanently sealing the cracks and leaks throughout the pipeline. All of these kinds of pipe relining techniques will leave behind a seamless and smooth pipe, which is made to last longer.

3. Cured-in place

If you need to restore trenchless relining systems then you must go for the cured-in-place piping technique. Most professional sewer and drain companies will remotely line a few portions of the pipe, which is broken without digging a trench.

Upon drying and cleaning the inside of your tube, the installers will then add the liner to the various cracked area. The liner will then be cured by using a spray of hot steam and that will get into all the pipe cracks present.

4.Pipe bursting

You will need the pipe-bursting method if your pipes are:

  • Severely damaged and need replacement of the entire pipe system or
  • You need to repair a larger section of sewer pipeline

The installers will begin by laying a “bursting head” at various access points of the pipe. The hydraulic power will be used for dragging the head through your pipe. While it will make its way through, it will break the old pipe and draw a new pipe behind it. The pipe will be a plastic material.
