Under-Slab Leak Detection & Foundation Pipe Diagnostics

Specialized sub-slab diagnostics to locate underground water-line failures beneath concrete foundations, without unnecessary excavation or guesswork.

Slab Leak Detection diagnostic service

What's included

Focused diagnostics for your property

  • Precision slab mapping
  • Inert tracer-gas testing
  • Sub-floor acoustic scanning
  • Thermal pattern analysis
  • Non-invasive access planning

Common signs this service addresses

Warm spots on the floor
Unexplained water use or high bills
Dampness at the slab edge or baseboards
Cracks in the foundation
Sound of water beneath the floor
Standing water near the foundation perimeter

Who this is for

Suitable properties and situations

Single-family homes, multi-unit buildings, and commercial structures built on concrete slab foundations where water lines run beneath or within the slab.

The process

How the inspection works

The inspection may combine line tracing to follow metallic pipe paths, pressure testing to confirm whether a leak exists in a specific section, acoustic listening for the sound of water escaping, thermal imaging for surface temperature patterns, and tracer-gas methods for difficult-to-locate leaks. Findings from several measurements are compared to narrow the likely area.

What to expect

You receive a documented assessment indicating the likely location of the slab leak. The detection process itself does not damage the foundation. Breaking through concrete for repair is a separate plumbing service. The findings help minimize the area that needs to be opened.

Limitations to understand

Sound and moisture can travel away from the actual leak point through concrete and soil. Non-metallic pipes cannot be traced electronically. In some cases, tracer-gas methods are needed for confirmation, which requires draining the line first.

Common questions

Can you find a slab leak without breaking the floor?

Diagnostic tools narrow the likely location to a small area. In most cases, this significantly reduces the section of floor that needs to be opened for repair. Complete confirmation may require minimal access in some situations.

What causes slab leaks?

Common causes include pipe corrosion, abrasion from contact with concrete or gravel, shifting soil, and water chemistry. The specific cause can usually only be determined after the pipe is exposed during repair.

Is slab leak detection the same as repair?

No. Detection identifies the location. Repair, which may involve spot repair, rerouting, or re-piping, is performed by a qualified plumber.
