A leak under a concrete floor is one of the most destructive and hidden plumbing problems a homeowner can encounter. Because water, heating and bathroom pipes are buried beneath layers of concrete, screed, tiles, stone, laminate, engineered wood and LVT, leaks often remain undetected for long periods. Homes across Shepperton — including Shepperton Green, Lower Halliford, Manygate Lane, Littleton, Upper Halliford and the wider Spelthorne area — frequently contain concealed pipework beneath solid floors, making expert detection essential.

Why Concrete Floor Leaks Are a Serious Problem
A hidden slab leak can cause serious damage, including:
- Hot or damp patches on the floor
- Loose or hollow tiles
- Musty smells and mould growth
- High water bills or constant water meter movement
- Boiler pressure dropping frequently
- Warped or lifting LVT, laminate or wood flooring
- Cracked plaster, flooring or screed
- Water migrating into adjacent rooms
- Long-term weakening of the slab structure
Shepperton’s mix of riverside homes, modern developments, bungalows and extended properties makes slab leaks a particularly common issue.
Common Causes of Concrete Floor Leaks in Shepperton
You may experience a slab leak due to:
- Burst or corroded mains water supply pipes
- Leaking central heating flow/return circuits
- Underfloor heating pipe splits
- Copper corrosion from concrete contact
- Bathroom feed or waste pipe leaks beneath tiles
- Pan connector or soil pipe failures
- Ground movement near the River Thames floodplain
- Poor workmanship in older refurbishments
- Pipe vibration, friction or expansion wear
Because these leaks are buried beneath flooring layers, accurate detection requires specialist diagnostic equipment.
How We Detect Leaks Beneath Concrete Floors
We use advanced, non-invasive tools to identify leak locations precisely:
Thermal Imaging
Reveals temperature anomalies and moisture patterns under floors.
Acoustic Leak Detection
Ground microphones detect vibrations from leaking pipes beneath concrete.
Tracer Gas Testing
A safe, odourless gas escapes from the leak point, providing pinpoint accuracy.
Moisture Mapping
Shows the spread of damp beneath slabs and into surrounding walls.
Pipe Isolation Testing
Determines if the leak is on the heating system, mains, or bathroom plumbing.
Borescope Inspection
Allows internal viewing beneath floors through minimal access points.
These tools enable us to locate slab leaks before flooring is lifted, preventing unnecessary damage.

- Bath waste or supply pipe issues
- Failed waterproofing (tanking)

We identify the exact cause of the leak before lifting tiles.
Ceiling Leaks Caused by Slab Failures
When water moves downward, the room below may show:
