Commercial Slab Leak Detection with GPR Technology
Locate hidden water leaks beneath commercial concrete floors without breaking through the slab. Our advanced GPR scanning pinpoints leak locations for targeted repairs, saving time and money.
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
