What is a slab leak, and how does it happen under a concrete floor?

A slab leak is a plumbing failure that occurs in the copper or plastic water supply lines running beneath your home’s concrete foundation. A combination of friction from soil movement, chemical reactions between the copper pipe and the soil, or poor original pipe installation usually causes these leaks. Over time, continuous rubbing against concrete or gravel can create a hole in the pipe wall.

Can high municipal water pressure cause my indoor pipes to develop leaks?

Yes, high water pressure puts excessive stress on your entire plumbing grid. If your home’s pressure-reducing valve fails and allows municipal water pressure to exceed 80 PSI, it can weaken pipe joints, loosen mechanical fittings, and cause older copper lines to split. Maintaining a safe pressure level protects your fixtures and prevents sudden indoor water line breaks.

Will electronic leak locating equipment work through thick tile or hardwood flooring?

Yes, advanced acoustic listening tools and thermal imaging sensors are designed to penetrate various flooring materials, including ceramic tile, hardwood, and laminate. The acoustic sensors detect the high-frequency sound of water escaping through the subfloor, allowing technicians to map the exact location of the break without damaging your expensive finished flooring.

Non-Invasive Acoustic and Thermal Leak Locating

Pressurized water escaping from a supply line behind a wall or under a slab creates a distinct vibrational frequency. Instead of tearing out drywall on a hunch, we use electronic ground microphones to map those acoustic waves through dense building materials and isolate the exact point of failure.

Thermal Imaging

Detects subtle temperature shifts caused by moisture pooling behind walls or beneath subflooring.

Acoustic Listening

Tracks pressurized leaks through concrete, tile, and hardwood without invasive cutting or drilling.

Targeted Inspections

Locating the exact breach first saves time and protects your home from unnecessary structural damage.

Tracking Under-Slab & Subterranean Line Failures

A pipe leak beneath a concrete foundation—commonly called a slab leak—can undermine your home’s structural stability. Escaping water erodes supporting soil under the slab, causing concrete to crack or settle unevenly. Finding these subterranean breaks requires specialized line-tracing tools and system pressure testing.

When we locate a slab leak, you don’t always have to jackhammer through your finished floors. Depending on the pipe’s condition, we evaluate whether a localized spot repair or an overhead pipe reroute makes the most sense. A reroute installs a new supply line through your walls or attic, permanently bypassing the broken pipe under the concrete.

Pressure Testing

Confirms system pressure drops and isolates whether the leak sits on the main supply line or interior distribution pipes.

Overhead Rerouting

Avoids tearing up hardwood, tile, or carpeted slab floors by running new lines around the damaged section.

Frequently Asked Questions

Why is my water meter spinning when all faucets are turned off?

A spinning water meter dial when no fixtures are running indicates an active, pressurized water leak. Water is constantly escaping somewhere along your main service line, beneath the foundation slab, or inside a wall. Shutting off the main indoor isolation valve reveals whether the leak sits in your yard or inside the house.

What is a slab leak and what causes it?

A slab leak is a break in the copper or plastic supply pipes running beneath a concrete foundation. Soil movement, friction, chemical reactions between bare copper and soil, or improper initial installation cause these failures over time, eventually wearing a hole through the pipe wall.

Can high water pressure cause indoor pipe leaks?

Yes, municipal pressure exceeding 80 PSI puts excessive stress on pipe joints, valves, and mechanical fittings. If your pressure-reducing valve (PRV) fails, high pressure can loosen joint connections and split copper or PEX lines.

How do I tell the difference between a roof leak and a plumbing leak?

Roof leaks correlate with rainfall, while plumbing leaks drip constantly regardless of the weather. If a ceiling or wall stain continues to expand during dry, sunny weather, a pressurized pipe behind the drywall is almost certainly leaking.

Does electronic leak detection work through hardwood or tile floors?

Yes, acoustic sensors and thermal cameras easily detect leaks through tile, hardwood, and laminate. High-frequency acoustic sensors pick up escaping water vibrations through subflooring, letting technicians map the break without damaging expensive finished floors.
