If your house or commercial building often experiences bathroom flooding or pinhole leaks, then there could be drainage problems that should be resolved as soon as possible. One of the most effective ways to fix your drainage problems is through drain lining. In addition, the process is relatively easy and cheap.
But what exactly is drain lining, and what are the benefits of commercial and residential pipe relining? Well, let’s find out.
What Is Drain Relining?
Drain relining is a way of repairing damaged drainage pipes that involves inserting a new pipe, known as a lining, into an existing damaged pipe rather than excavating it. It is a type of No-Dig Repair Technology that employs a drain sleeve that is similar to glass-reinforced plastic. It should be done by experts such as The Drain Man.
This method can be used to fix leaking or open joints as well as radial cracks brought by a blockage, so you can still use the drain lining procedure to assist you in unblocking drains.
The Process Of Drain Relining
1. Inspection
The inspection of drainage pipes is the first step in the drain relining procedure. That’s why you must pay attention to it if you need to unblock a drain. Unlike the traditional method of drain replacement, which requires pipe excavation, the drain relining process employs CCTV survey technology or plumbing camera inspection. This inspection determines the location and degree of any pipe damage.
2. Debris cleaning
Following the inspection, the pipes are cleaned to avoid any obstructions during the relining process. The debris is removed with a robotic cutter that can cut through steel and concrete. Following that, a high-pressure water jet is used to clean any debris from the pipe. This ensures that the pipe wall is properly bonded.
3. Re-inspection
Before the new drain liner is installed, the pipes are thoroughly inspected to verify that any possible incursions have been eliminated.
4. Lining preparation
At this step, the method of relining, as well as the exact amount and type of pipe lining required, are determined. This is due to the fact that different types of liners are employed in different scenarios. Flexible liners, for example, are employed when the pipes are bent and manoeuverability is required.
5. The installation
There are two methods for installing the technology. The first is accomplished by a process known as inversion. A resin is put into the drain liner and rolled continually to ensure that it is evenly distributed on its body. It is then placed into the damaged pipe using inflated airbags or water pressure to conform the liner to the pipe walls.
It might also be done using GFRP UV pipe lining. Using ropes and winches, the pipe lining is dragged into the damaged pipe.
Both procedures ensure that the liner is perfectly matched to the pipe’s surface. This ensures proper drainage.
6. Curing
The curing process follows installation. This entails hardening the resin to guarantee that the lining remains in place. When installed by inversion, the cure time can be sped up by pouring hot water down the pipe. UV lighting is required to cure the lining to full hardness in GFRP UV pipes.
7. Re-inspection at the end
Following the repair of the damaged part of the drainage pipe, a final inspection is performed to guarantee that the pipe is as good as new. This includes visual inspections with CCTV surveys and leak detection equipment assessments.
Benefits Of Drain Relining
- Reduce drain repair costs significantly
- Faster repairs
- Minimal disruption of activities
- A non-destructive way to secure your pipes because there is no digging required
