What Causes Water Leaks Under Concrete Slabs?

Slab leaks occur when a pipe starts to leak underneath your foundation. Often, this happens due to wear or mechanical failure. High water pressure, shifting soil, and corrosion can make this issue more likely. In addition, chemical reactions between the metal pipe and soil can lead to premature failure.

Common Signs of a Slab Leak

To avoid serious water damage and costly repairs, watch out for the following signs of a potential leak.

An Unexplained Increase in Water Bills

If your water bills increase significantly, it indicates that water is being lost somewhere in your plumbing system.

Warm or Damp Spots on Floors

Warm spots can occur if a hot water line is leaking. Similarly, damp spots mean that something is leaking beneath the flooring.

The Sound of Running Water When Taps Are Off

You should never hear the sound of running water if you aren’t using water. If you do, you should investigate the cause.

Cracks in the Walls or Flooring

When water starts to leak, it can cause the foundation to shift. Eventually, this results in cracks forming in your walls and flooring.

Low Water Pressure Throughout Your Home

If water pressure suddenly drops, it may be due to a leak reducing the pressure. To diagnose the source, reach out to one of our experienced plumbers.

How To Detect a Water Leak Under a Slab Yourself

1. Check the Water Meter for Continuous Flow

To determine if there is a leak in your home, shut off every faucet. Then, check your water meter. If it shows that water is still being used, you have a leak somewhere.

2. Use a Moisture Meter or Thermal Camera

While a moisture meter is effective for finding spots of moisture under your floor, thermal cameras can help you spot temperature changes from a hidden leak.

3. Inspect for Musty Odors or Mold Growth

When leaks occur, the added water can cause mold and mildew to grow.

Professional Methods for Detecting Slab Leaks

While it is possible to detect a slab leak on your own, our expert plumbers possess special diagnostic tools that we can use to find leaks.

4. Acoustic Leak Detection

With the help of acoustic devices, we can hear where a leak is occurring below the ground.

5. Infrared Thermography

Infrared thermography allows us to map out different temperatures under the ground, so we can easily see any existing leaks.

6. Camera or Line Inspections

Through this kind of inspection, we thread a camera through your pipes to visually inspect for indications of a leak.

7. Pressure Testing and Isolation Techniques

Finally, our plumbers can spot slab leaks by isolating and testing different plumbing zones to make sure the pressure levels are correct.

How To Repair a Water Leak Under a Slab

Once a water leak is detected, there are a few steps we can take to repair the issue.

Spot Repairs and Pipe Relining

If the leak is small, the plumber can do a spot repair. Minor repairs can also be fixed through pipe relining, which is when an epoxy lining is slid into the pipe as a reinforcement.

Rerouting or Trenchless Replacement

For major damage, we can either reroute the pipe around the slab or use trenchless replacement. With trenchless replacement, you can avoid property disruption and enjoy a faster repair process.

How To Prevent Future Slab Leaks

To prevent future leaks, it’s essential to schedule routine maintenance appointments. Our plumbers can treat minor problems before they escalate into major disasters, so you are less likely to have leaks in the future.

Additionally, you should avoid chemical drain cleaners and replace older pipes.
