This page is here to help homeowners in Hampshire 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.

Concrete floor leak detection in Hampshire is carried out by The Leak Hunter using structured, non-invasive investigation designed to locate leaks beneath solid floors without unnecessary damage.

We regularly carry out concrete floor leak detection across Hampshire — including Southampton, Portsmouth, Winchester, Basingstoke, Farnborough and surrounding areas — where modern extensions, underfloor heating systems and concealed pipework are frequently installed beneath concrete slabs and bonded screed floors.

Once hidden beneath tiled, stone, timber or engineered floor finishes, these systems cannot be assessed visually. When leakage develops beneath a solid floor, the visible damp rarely identifies the true escape point. Moisture can migrate through screed and insulation layers before surfacing elsewhere, while heat from leaking pipework can spread across wider floor areas.

Across Hampshire’s detached homes, modern developments, converted properties and rural residences, incorrect diagnosis can quickly lead to unnecessary structural opening, avoidable disruption and escalating reinstatement costs.

We do not begin by lifting tiles or breaking concrete.

We begin by confirming the fault.

At The Leak Hunter, concrete floor leak detection across Hampshire is carried out using structured non-invasive testing selected according to floor construction, pipe configuration and property layout. Each investigation is adapted to the building itself rather than approached generically.

The affected zone is narrowed before access is agreed.

We confirm the precise leak location first.
Structural access follows only once the fault is proven.

Concrete floor leak detection in Hampshire is not exploratory work.
It is controlled investigation followed by targeted repair.

Why Specialist Concrete Floor Leak Detection Is Different

Leaks beneath concrete or screeded floors cannot be located by surface inspection alone.

In many Hampshire 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 Hampshire, 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 Hampshire

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 Hampshire – 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.
