Understanding Repair Options for East Texas Foundations

Option A: Direct Concrete Jackhammering (Spot Repair)

Once non-invasive detection pinpoints the leak within 12 inches, plumbing technicians jackhammer a clean access hole through the slab foundation. The leaking copper section is removed, replaced with heavy-gauge type L copper or brass compression fittings, pressure-tested, and backfilled with concrete.

Option B: Overhead Wall & Attic Reroute (Non-Destructive)

Instead of cutting expensive hardwood or custom tile flooring, plumbers abandon the leaking line beneath the slab entirely. A new commercial-grade PEX line is routed through interior wall cavities and ceiling joists, completely bypassing the foundation.
