Do you have consistently unpleasant odours in your backyard for no reason?

Are you hearing constant gurgling noises even when all the taps are turned off? Do you have wet floors for no reason?

Please continue reading to learn more about why these things are happening and how to find a reliable solution for these problems.

If you are experiencing any of the above problems, this usually means that the drain pipes in your house are due for repairs.

Since the drain pipes are usually buried underground, it’s pretty hard to check them out to find the cause of the exact problem.

There are two options available to you when it comes to the repair of damaged drainage pipes.

One of the options is to excavate and replace the damaged drainpipes.

This is not only an extremely difficult process but also expensive, especially when drainpipes are buried deep under retaining walls or driveways.

Thankfully, there is another option which is known as drain relining.

About Drain Relining

Simply put, it’s a method of repairing the lining on drains.

It’s known by many other names including sectional pipe repair, no-dig drain relining, trenchless pipe relining, internal epoxy patching, drain rehabilitation and cured-in-place pipe among others.

This method of repair is widely used all around the world.

In this method, a new pipe which is known as lining is inserted inside the existing damaged pipe which turns it into a completely new pipe.

This repair method can be used for fixing radial cracks, circumferential cracks, leaking joints as well as open joints among other issues.

Drain patch relining is a similar process. In this method, a drain patch is used instead of relining the whole pipe with the help of a pre-shaped pipe.

In this case, an epoxy resin is used to fill up the spread out patch.

This patch is inserted into the damaged pipeline with the help of a tool called pipe packer.

The pipe packer is carefully and slowly inserted into the damaged drain.

Once the patch reaches the site of the defect, it is inflated and left there for around an hour before removal.

Around an hour of curing time is enough for the new patch to cover the leakage.

Drain patch relining is extremely effective when a full relining is not required and only a small damaged section of the pipe needs to be repaired.

The Process

The first step is the inspection. With this method, CCTV survey technology is used to determine the extent and location of the damage.

Once the inspection has been completed, cleaning is done in order to get rid of any obstructions.

If there are tree roots, a robotic cutter is used to remove such intrusions. This is followed by a high-pressure water jetter to clear any remaining debris.

Before relining, pipes are inspected again to ensure complete removal of all intrusions.

Once the pipes are clean, the type of pipelining and amount is decided.

Different situations call for different types of liners. In case of curved pipes, flexible liners are used.

As far as the installation process is concerned, there are various options.

In the inversion process, a resin is poured into the liner and it is evenly distributed.

Inflated airbags are then used after insertion of the liner into the damaged pipe in order to shape it to the pipe walls.

In some cases, water pressure is also used. Another method is UV pipelining.

In this method, cables and winches are used to pull the lining into the damaged pipe.

Installation is followed by the curing process. This ensures hardening of the inserted resin to keep the lining in its place.

In the case of the inversion process, the resin cures either by itself or hot water is run through the pipe to speed up the process.

In case of UV pipelining, UV lighting is used for curing.

Once the damage has been fixed, a final inspection is done to make sure that the repair process is complete.

Once again, CCTV survey technology is used along with leak detection equipment.

Conclusion

Drain patch relining offers a number of advantages in terms of lower costs, minimal disruption and high speed of repairs.

As far as the cost savings are concerned, drain patch relining is considerably cheaper when compared to excavation and replacement.

It is also an eco-friendly process as the lining and resin are environmentally friendly materials.
