This page is here to help homeowners in Kent who may be experiencing a leak beneath a concrete floor, including issues affecting solid floors, screed, tiled surfaces, and concealed pipework running below the property. The Leak Hunter specialises in locating and repairing concrete floor leaks, using non-invasive techniques to trace the source accurately before recommending the most appropriate solution.
The Leak Hunter is a specialist leak detection company, so if your symptoms relate to a different type of leak, we can still help. You can explore our other leak detection services using the menu above, or contact us and we’ll point you in the right direction.
Why Specialist Concrete Floor Leak Detection Is Different
Leaks beneath concrete or screeded floors cannot be located by surface inspection alone.
In many Kent properties, water and heating pipework is embedded within bonded screed, tiled finishes or solid concrete slabs. The visible symptom — damp patches, loose tiles or discoloured grout — is rarely positioned directly above the leak itself.
Breaking out flooring without confirmed diagnosis increases cost, disruption and the risk of unnecessary structural damage. Exploratory excavation frequently results in excessive removal before the fault is accurately identified.
Specialist concrete floor leak detection focuses on precision first.
We confirm the exact escape point within the slab or screed before any tile is lifted or concrete is opened. Acoustic detection, tracer gas testing, thermal assessment (where heating circuits are present) and moisture mapping are applied methodically according to floor construction — not used generically.
Controlled diagnosis prevents uncontrolled damage.
The objective is simple:
Confirm the precise leak location before any structural disturbance begins.
This is structured concrete floor leak detection focused on accurate diagnosis and controlled repair planning.
When a Concrete Floor Leak Needs Specialist Investigation
If a leak develops beneath a concrete slab, screed, or tiled finish, the early signs are often subtle — and they rarely sit directly above the fault.
You may need specialist concrete floor leak detection if:
- Damp patches appear on tiled or solid flooring
- Grout lines darken, soften or begin to break down
- Localised areas feel warm without explanation
- Tiles sound hollow, lift, or loosen unexpectedly
- Moisture rises at floor edges or through joints
- Water usage increases without any visible internal leak
Where pipework runs within the slab, pressure loss (heating) or rising water bills (mains/domestic supply) may also indicate concealed leakage beneath the floor structure.
Early investigation allows the affected zone to be narrowed before any controlled access begins.
Where Concrete Floor Leaks Typically Occur
In Kent, pipework is commonly buried within:
- Bonded screed beneath tiled finishes
- Concrete slabs in ground-floor construction
- Solid extensions with services run through screed
- Wet underfloor heating circuits embedded below floor finishes
- Concealed hot and cold supplies routed beneath solid floors
Concrete-floor leaks most often develop around joints, transitions, and sections exposed to movement, historic workmanship, or long-term material fatigue.
Because floor construction spreads moisture, the visible symptom is rarely positioned directly above the leak.
Our testing narrows the affected zone first, so only the required section is opened.

How We Locate Leaks Beneath Concrete & Screeded Floors
We follow a defined diagnostic sequence designed specifically for buried pipework within solid floor construction.
Before any tile is lifted or screed is opened, we confirm where leakage is occurring and narrow the affected zone.
We begin by assessing floor construction, pipe material and system layout. Where heating circuits are present within the slab, we determine whether pressure loss relates to underfloor heating pipework or a domestic water supply line embedded within the structure.
Where concealed leakage is suspected, we deploy specialist non-destructive methods:
Thermal assessment — Used where heating pipework is present to identify abnormal heat distribution within the floor.
Acoustic detection — We isolate the sound frequency of escaping water travelling through concrete and bonded screed.
Tracer gas testing — A safe inert gas is introduced into the pipework and detected at the precise escape point, even through tiled finishes or solid slabs.
Moisture mapping — We define the extent of damp migration before controlled access begins.
Each method is selected according to floor structure and pipe configuration — not applied generically.
Our objective is clear:
Confirm the exact leak location before any structural break-out takes place.
Precision diagnosis limits disruption, protects floor finishes and ensures repair is targeted to the confirmed fault area.
How Our Accurate Diagnosis Prevents Unnecessary Cost
Concrete floor leaks are frequently misdiagnosed.
Tiles may be lifted without confirmation. Screed may be opened in the wrong location. In some cases, large sections of floor are removed before the leak is accurately identified.
By confirming the precise escape point first, we limit structural disturbance and avoid exploratory break-out.
Controlled diagnosis reduces repeat labour, protects floor finishes and prevents unnecessary reinstatement costs.
Where investigation confirms that the issue does not originate within the concrete floor itself, we extend testing methodically to identify alternative sources, such as concealed internal pipework or mains supply faults.
The objective is not simply to find damp.
It is to confirm the exact cause before structural access begins.
Confirmed Leak Repair in Kent
Once the precise leak location has been confirmed, we provide a defined repair plan before any floor finish is disturbed.
Access is limited strictly to the identified fault area.
Where required, tiles are lifted in a controlled manner. Screed or slab sections are opened only where testing has confirmed the escape point. Exploratory break-out is avoided.
We repair or replace the affected pipe section as appropriate to the system type and floor construction. Where heating circuits are present, we ensure the wider sealed system is assessed and stabilised following repair.
After corrective work is completed, the affected section is pressure tested and verified before any reinstatement begins.
Only once system integrity is confirmed is the investigation considered complete.
All completed repair work is backed by a 12-month warranty.

Concrete Floor Leak Detection Kent – FAQs
Do you need to remove the entire floor to find the leak?
No. We confirm the precise leak location before any floor finish is disturbed. Access is limited strictly to the identified fault area.
Can you detect leaks beneath tiled or screeded floors?
Yes. We use acoustic detection, tracer gas testing and moisture mapping to locate leaks beneath solid finishes without unnecessary break-out.
What if the leak is within a concrete slab?
Leaks within concrete slabs can be located accurately using specialist non-destructive methods. Once confirmed, only the affected section is opened.
Could the leak relate to underfloor heating pipework?
If heating circuits are embedded within the floor structure, we determine whether the leak originates from the heating system or a domestic water supply line before access begins.
Is concrete floor leak detection covered by insurance?
Where required, we can provide structured trace and access documentation detailing the confirmed fault location and the diagnostic process undertaken.
Insurance, Compliance & Professional Standards
All our work is carried out under comprehensive insurance cover and in accordance with recognised national safety and water system standards.
As Gas Safe registered engineers and a WaterSafe approved company, we are authorised to assess, isolate and repair domestic heating and water systems safely and compliantly.
Where required, structured trace and access documentation can be provided for insurers, clearly detailing the confirmed fault location, the diagnostic process undertaken and post-repair pressure verification.
