A slab leak — a pipe break in the water supply or drain lines running under your UAE home's concrete floor — is one of the most difficult plumbing issues to diagnose and repair. Contractors UAE uses electronic leak detection and acoustic listening equipment to locate slab leaks across Dubai and Sharjah without unnecessary concrete cutting.
Last Updated: July 28, 2026
Slab leaks in UAE properties are most common in villas and ground-floor apartments where water supply pipes or underfloor heating pipes run beneath the concrete structural slab. Symptoms of a slab leak: unexplained warm areas on tiled floors (indicating a hot water pipe leak beneath the slab); damp patches appearing on tiled floors without visible surface water source; a DEWA meter that moves continuously even with all taps closed (indicating continuous water loss into the ground beneath the slab); mold or damp smell appearing in rooms where the floor is tiled directly onto the slab without a screed void. UAE's hard water chemistry accelerates the corrosion of copper pipes in the alkaline concrete environment, making slab leaks more common in UAE villas with copper underfloor pipe runs than in equivalent properties in soft-water markets.
Our slab leak detection process uses three techniques in sequence: thermal imaging camera survey of the floor surface — a hot water pipe leak beneath the slab creates a warm zone visible to the thermal camera; acoustic detection using a listening device placed against the floor surface that detects the sound signature of water flowing through a pipe breach; pressure drop testing where sections of the pipe system are isolated and pressure-tested to confirm which pipe circuit is leaking. The combination of these three methods allows us to pinpoint the leak to a 0.5–1 metre accuracy before any concrete is broken — minimising the floor opening required for the repair.
Direct repair: breaking out the concrete or screed above the identified leak point, repairing or replacing the failed pipe section, pressure testing the repaired section and reinstating the concrete and floor finish. This is the most straightforward approach for small, accurately located leaks. Pipe bypass: rather than breaking out the floor to find a corroded copper pipe that may have multiple failure points, installing a bypass pipe that runs above the slab surface (typically in the ceiling void of the room below, or surface-mounted in a duct along the wall) to replace the failing underfloor run entirely. This avoids extensive concrete work and is often the most cost-effective approach when the underfloor pipe is aged and likely to develop further failures. Pipe lining: for accessible pipe runs, inserting an epoxy resin liner inside the existing failed pipe. This is the least disruptive approach but requires that the pipe bore is adequate for the liner and that access from both ends of the pipe run is available.

Key signs: warm floor tiles in specific areas with no surface water source, unexplained water consumption increase on the DEWA bill, mold or damp smell at floor level, or a meter that continues moving when all taps are off. Call us for a detection survey.
Detection and diagnosis: 2–4 hours. Direct repair of a located leak: 1–3 days including concrete breaking, pipe repair, concrete reinstatement and floor tile reinstatement. Bypass pipe installation: 1–2 days.
Most UAE home insurance policies cover sudden and accidental water damage from burst pipes, which includes slab leaks. Damage from gradual leaks may be excluded. We provide detailed documentation of every slab leak repair for insurance claim purposes.
Yes — our thermal imaging and acoustic detection methods locate the leak accurately without any floor opening. The concrete is only broken at the specific pinpointed location after detection confirms the exact leak position.
