Slab Leaks &
Foundation Cracks?
Under-slab copper line leaks cause soil erosion and foundation cracking. Pinpoint leaks electronically and repair them cleanly without flooring damage.

How Alkaline Soils & Seismic Shifts Cause Pipe Ruptures Under Concrete
California properties are commonly built on concrete slab foundations rather than deep crawlspaces or basements. This building practice places water supply lines directly underneath thick layers of concrete. Over time, high soil alkalinity reacts chemically with copper pipelines, producing pitting corrosion and micro-fractures. In addition, low-level seismic tremors cause ground settling, placing high shear stress on lines and resulting in hidden slab leaks.
Signs of a slab leak include warm spots on floor tiles, wet spots on carpets, a sudden spin on your water meter, or drops in water pressure. CA Plumbing Company uses advanced acoustic sound locators and thermal camera scans to pinpoint the leak center. Once found, we prioritize non-destructive repairs such as external tunneling beneath concrete or routing flexible PEX lines overhead to completely bypass the failed under-slab section.
Non-Destructive Foundation Solutions
-
✓
Acoustic sound mapping: Electronic amplifiers locate exact water exit spray frequencies under thick concrete floors.
-
✓
Under-Slab Tunneling: Excavating a small access shaft outside the wall to tunnel under the floor, saving custom flooring.
-
✓
Overhead PEX Re-Routing: Pulls new supply lines through walls and ceiling joists to completely bypass the damaged under-floor pipe.
Expert Foundation Slab Leak Diagnostics & Pipe Re-Routing
Pressurized supply lines running beneath concrete foundations are vulnerable to friction failures caused by soil settlement, ground expansion, and seismic vibration. When a pipe ruptures under a concrete floor, it is known as a slab leak. CA Plumbing Company coordinates structural slab leak evaluations and repairs across California to protect your building's foundation from erosion.
Horizontal Under-Slab Tunneling:
Standard slab leak repairs often involve breaking through tile or hardwood flooring with jackhammers. To prevent this interior damage, we offer precision under-slab tunneling. Our teams excavate a small access shaft outside your building's perimeter and tunnel horizontally beneath the foundation to replace the broken pipe section. This preserves your custom floors and isolates repairs away from living areas.
Flexible Overhead PEX Re-Routing:
If tunneling is not structurally feasible due to soil instability, we perform overhead PEX pipe re-routing. Instead of repairing the broken line under the floor, we abandon it entirely. We pull brand-new, flexible high-durability cross-linked polyethylene (PEX) supply lines through your wall cavities and ceiling joists. This completely bypasses the concrete foundation and eliminates the risk of future slab leaks.
