You may notice leaking from the concrete or around the structure of your 
home/building. This is a sign that there is an issue with your underground 
piping. Water leaking, if ignored can cause major structural damage to your 
property and as a result, can be rather costly to repair.

Pipe inspection

camera, your plumber will inspect the pipes and confirm if pipe relining is the best 
outcome for you.
Pipe cleaning and preparation
Before a textile liner can be inserted, the pipes must be thoroughly cleaned of debris 
and rubbish. A high pressure jet blaster will have the pipes clear and clean in no time.
The glossy sheen on the surface of PVC piping is removed using a high-speed sanding 
panel. This offered the liner a good texture for permanently sealing the pipe.

OPTION B:   REPAIRING UNDERGROUND PIPES WITH PIPE 
REPLACEMENT
When homes are built on a concrete slab the outer edges are approximately up to 
600mm thick, whereas the remainder of the slab is 100-150mm thick. This gives the 
home a strong foundation and keeps it structurally sound in all weather conditions. 
The only issue is to have a house on a slab where all plumbing is laid before. This 
makes for hard times when you have issues with your plumbing.

 What to expect from this repair solution
Looking at the thickness of the slab you can understand that there is a thick layer 
of concrete to get through before we can repair any pipework. Unfortunately, this 
can be a costly and timely procedure. On top of this we need to factor in costs of 
pouring new concrete again once the pipes have been repaired.
Additionally, this cause further damage and take days or even weeks to complete 
repairs depending on the complexity of the work. Your water leak detection report 
will show exactly where the issues are and where possible your plumber will give 
you a few options for repairing the pipe system.

 Times when there is no alternative except for pipe replacement.
When your pipes are severely damaged or collapsed entirely there is no alternative 
but to replace the pipe Additionally, it would be less likely that you will need to take 
such dramatic action to repair your pipes if you discovered the problems sooner 
and corrected them.
A complete pipe replacement could fix your leaking pipes, but this is an extreme, 
expensive solution for damaged pipes. Along with the evacuation, pipes under the 
slab create an addition obstacle. The other issue is risking damaging other parts of 
your home, including tiling and home decor.

time consuming digging and it offers a long lifespan. Pipe relining is a great 
long term solution to fix broken pipes.
