Here Is What You Need To Know About Drain Relining

Drain relining is a modern method of repairing damaged drainage pipes by fixing new pipes called liners to existing damaged pipes instead of resorting to traditional excavation methods. It is a form of minimally invasive repair technology.

Drain Relining can be used to repair leaks or open joints and circumferential or radial cracks caused by blockages. It also acts effectively against the root intrusion of old clay drain pipes that are most vulnerable.

Closely related to the relining is a process called drainage patch repair. Here, unlike relining using prefabricated pipes, the main material used is called a drainage patch.

In the drain relining process, the patch is spread out, filled with epoxy resin, and wrapped on a pipe packer tool. Then the packer slowly and cautiously inserted into the waste drain to the area with the defect and is inflated to seal it shut. It is removed after being left untouched for about an hour.

How is Drain Relining conducted?

Inspection

The first step in the process is inspecting the drainage pipes. Contrary to the old method, this method uses CCTV technology to determine the affected area and assess the damage’s extent. This does not involve excavating all the drainage pipes to look for the defect and saves cost and time.

Clearing Debris

Once the inspection is completed, the next step involves cleaning the pipes. The drainage pipes are cleared of any obstructions, including tree roots which can be cut using a robotic cutter that can penetrate through steel and concrete. After clearing out any obstructions, a high-pressure water system is used to clean out the remaining debris from the drainage pipes. This step makes sure that there is a good bond between the pipe and the wall.

Reinspection of the drainage area

The next step is re-inspecting the area to make sure that it is clear of all debris and any obstruction that may have been left behind. This gives the go-ahead to the next step of drain relining.

Preparation of the draining lining

In this step, the workers will assess the method of drain relining which is to be used and determine the exact amount of pipelines that would be required. It is essential to evaluate these things as different lines are used for different situations. Some situations where the pipes are curved may call for more flexible liners to have more maneuverability.

Installing

These two methods of installation. The first one requires the resin to be poured into the drain and repeatedly rolled to ensure it has been distributed evenly throughout the body. Then this is inserted into the damaged drain with the help of inflated airbags to help shape the lining to the walls of the pipe. This method is called inversion. The other method is called GFRP UV drain relining, where the lining is pulled to the damaged using cables winches.

Curing

Once the installation procedure is completed, the next step involves curing. This means hardening the resin to make sure that the relining stays in place.

Final re-inspection

Again, with CCTV technology, the workers will check if the drain relining has been installed in the right place and is being held up. At this stage, if they notice any mistakes, they can fix them right away without causing you any more troubles in the future.

Final Words

Therefore, as you can see that this modern technology has several benefits which outweigh the use of excavating the pipes fully. They not only save time and cost but also cause minimum waste. Therefore if you are looking to solve your pipe problems use drain relining for the best results.
