What is a Commercial Slab Leak?

A slab leak occurs when water pipes embedded in or running beneath a concrete foundation develop leaks. In commercial properties, these leaks can go undetected for months, causing extensive damage to the foundation, flooring, and building structure.

Commercial slab leaks are particularly challenging because of the large floor areas involved, the thickness of commercial concrete slabs, and the complexity of plumbing systems in multi-tenant or industrial buildings.

Our GPR technology penetrates concrete to detect moisture patterns and anomalies that indicate leak locations. This non-destructive approach means we can scan large commercial floors quickly without cutting into the concrete or disrupting your operations.

Why GPR for Commercial Slab Leaks?

  • Scans through concrete up to 18 inches thick
  • Covers large floor areas efficiently
  • No drilling or cutting required for detection
  • Real-time imaging shows moisture patterns
  • Pinpoints leak location within centimeters
  • Works on reinforced and post-tensioned slabs

Common Sources of Commercial Slab Leaks

Understanding where slab leaks originate helps in faster detection and more targeted repairs.

Supply Line Leaks
Hot and cold water supply pipes embedded in or beneath the concrete slab can corrode, shift, or develop pinhole leaks over time.

Common Causes:

Pipe corrosion
Soil movement
Poor installation
Material degradation
Drain Line Leaks
Waste and drainage pipes under the slab can crack, separate at joints, or become damaged by ground movement.

Common Causes:

Root intrusion
Ground settling
Joint failure
Material failure
Radiant Heating Leaks
In-floor heating systems embedded in concrete can develop leaks at connections or due to tube damage.

Common Causes:

Connection failures
Tube punctures
Thermal stress
Chemical degradation
Fire Suppression Lines
Underground fire sprinkler supply lines and connections can leak without visible signs above the slab.

Common Causes:

Corrosion
Freeze damage
Connection issues
Pressure fluctuations
