Sometimes a more major repair is necessary.
Here’s a good example of exactly that.
The watering had burst under the concrete slab of the home on the Gold Coast.
We used a Leak Detector to find the point of origin. Cut the concrete with a Demolition Saw. Dug until we identified the pipe. Made the repair to the Poly Pipe.
We also finished off the job by backfilling the hole with sand to protect the pipe and then soil to armour the sand. A layer of concrete was then laid to get the footpath back to its original condition.
