Pipe Relining vs Pipe Replacement

why dig when you can pipe reline - discover keyhole technology

The sewers, drains and pipes in your home can become old and fragile over time. Damage to the structure of these systems is common and can happen due to the use of poor materials, settling of the earth which can cause collapsed drains or even tree roots penetrating the pipes and growing into the interior.

Damaged pipes are a serious problem and can have a severe impact on the proper functioning of your home, so what are the options for having them fixed?

Pipe replacement and pipe relining are both popular methods for fixing damaged pipes in the home, however, while they might sound similar there is a big difference between the two techniques.

Pipe Replacement

Pipe replacement involves excavating the ground around the pipe, this might involve breaking through the concrete in your driveway or digging up your garden. Once the pipe is exposed, the damaged section is removed and replaced by a new pipe.

Pipe Relining

Pipe relining specialists will first drain your pipes of water and use a thin, flexible camera to inspect the damage. Once they have ascertained the extent of the problem they will insert an epoxy resin material into the pipe and begin relining the walls. This is normally done through a small “keyhole” that requires a very small piece of pipe to be exposed to allow the epoxy resin to be inserted into the existing pipe. The epoxy resin will then set, harden and become the new walls of the pipe.

What are the other differences between Pipe Relining and Pipe Replacement?

The time it takes to complete the fix: Perhaps the biggest difference between the two solutions is the time it takes to repair the pipes. Between excavating, replacing the pipe and repairing the dig site, pipe replacement can take a couple of weeks to complete. Pipe relining, on the other hand, only needs as entry point into the pipes and can be completed within a day.

The cost of having your pipes repaired: Due to the big difference in time taken to complete the fix and the fact that there is no need to restore an excavation site pipe relining can be significantly cheaper than replacement.

Durability of the repair: While people often think that pipe replacement offers a stronger fix this might not be the case. The epoxy resin used for pipe relining can be extremely durable and last up to 50 years, which is far better than PVC pipes. Relining also doesn’t rely on joins, which is commonly an entry point for roots that can do significant damage to pipes over time.

Type of repair required: This is an important consideration when looking at the differences between pipe replacement and pipe relining. Pipe relining can take care of most problems to damaged pipes including cracked pipes, broken tee junctions and root damage. However, if the damage is too severe and there is no way to insert the epoxy resin lining, then pipe replacement might be your only option.
