Slab Leak Repair in Hanford, CA

Electronic Slab Leak Detection & Repair in Hanford

Most homes in Hanford are constructed on concrete slab-on-grade foundations with domestic hot and cold copper supply lines buried directly beneath the slab. Over years of thermal expansion, contact with corrosive Central Valley alkaline soil, and abrasive friction against rocks, underground copper pipes develop microscopic pinholes known as slab leaks. Warning signs include unexplained hot spots on your tile or vinyl floor, soaring municipal water bills, damp carpet, or the sound of water running when all faucets are shut. We use non-invasive acoustic listening devices and thermal imaging to locate underground leaks, recommending reliable overhead PEX bypasses that eliminate expensive concrete jackhammering.

Specialized Field Protocol

Sub-Slab Acoustic Pinpointing & Reroutes

• Dual-frequency acoustic ground disc amplifying underground water hiss
• Non-destructive pinpointing preventing random concrete jackhammering
• Cost-effective overhead PEX bypass routing eliminating future slab leaks

How We Complete Your Service

1. Acoustic & Thermal Foundation Survey: Using calibrated ground microphones and infrared thermal cameras, our technician pinpoints the exact underground acoustic resonance or heat bloom under the slab.
2. Pressure Isolation & Manifold Testing: We isolate individual hot and cold supply loops at the manifold to confirm pressure loss on the failing branch before recommending repair options.
3. Overhead Bypass Installation: A continuous run of commercial Uponor PEX-A tubing without sub-floor joints is routed through attic or wall cavities, permanently bypassing the failing underground pipe.
4. Final Pressure Test & Clean Restoration: The newly routed bypass is pressurized to municipal levels, the old sub-slab pipe is permanently capped, and all access openings are prepared for clean drywall restoration.
