Slab & Concrete Leak Detection Services
Slab & Concrete Leak Detection Services – Accurate, Non-Invasive, Trusted
Expert Slab Leak Detection Without the Mess or Guesswork
Water leaks under concrete slabs can go unnoticed for weeks — sometimes months — until they cause major structural damage, mould growth, or rising water bills.
At Local Leak Detection Specialist, we use non-invasive slab leak detection equipment to accurately pinpoint the leak location beneath floors, tiles, concrete, and driveways — without unnecessary cutting, digging, or disruption.
We service residential, commercial, strata, and industrial properties across Sydney, Wollongong, Southern Highlands, and beyond.
Common Signs of a Slab Leak
- Water bill is increasing for no obvious reason
- Damp spots on floors, carpets or near walls
- Hot areas on floors caused by leaking hot water pipes
- Mould, musty smells or warped floorboards
- Constant running water noise when taps are off
- Reduced water pressure
- Hairline cracks in tiles, concrete or foundations
How We Find Leaks Under Concrete Slabs
We use a multi-method, non-destructive process tailored to each property. Our slab leak detection toolkit includes:
- Acoustic listening equipment – to identify pressurised pipe leaks through solid concrete
- Tracer-gas detection systems – for silent or low-flow leaks where sound is minimal
- Thermal imaging cameras – for locating leaking hot water lines under floors
- Moisture meters & mapping – to confirm rising damp or lateral water migration
- Service locators – to trace pipe runs through slabs and under floors
This ensures we detect the leak before you rip up tiles, flooring or driveways unnecessarily.
Ideal for Residential, Commercial & Strata Properties
Slab leaks can happen anywhere — and we’ve seen it all:
- Under bathroom or ensuite floors
- Beneath kitchens, laundries or garages
- Leaks running below concrete pathways or driveways
- Hidden beneath office floors or factory slabs
- Travelling between strata units or duplexes
Whether you manage a high-rise, live in a villa, or run a commercial premises — we’ve got the tools and experience to find your leak fast.
