Underground Leaks · Brisbane & SEQ
Leaks under a slab or in the yard can stay hidden for a long time while damage builds up. Our licensed plumbers locate and repair them across Brisbane and South East Queensland.
The short answer
An underground or slab leak is a water leak in pipework buried in the ground or beneath a concrete slab. The Plumbing Gang’s licensed plumbers use water meter tests, pressure testing, acoustic sounders and thermal imaging to find the leak, then explain repair options with fixed-price choices before work starts.
Available 24/7 across Brisbane and South East Queensland. Urgent jobs are reached within 60 minutes where available, with fixed-price options before any work starts.
Underground leak detection · Brisbane & SEQ
1300 671 525Book a plumberBill gone up?
The pipe from your water meter to the house runs underground, so a leak there can go unnoticed for months. The usual signs are a higher water bill, a meter that moves with all taps off, or a patch of lawn that’s greener or soggier than the rest.
We locate the leak with detection equipment and make a small, targeted repair instead of digging up the whole yard.
