When a home is built on a concrete slab rather than a basement, all of the water lines are installed before the concrete foundation is poured. The water and drain lines run up through the concrete and enter the house at various locations to service the kitchen, bathrooms, and other areas of the home. If a leak develops in any of the piping that runs under the concrete slab, it is called a slab leak.

As you can imagine, it is very challenging to locate any water leak concealed by a thick slab of concrete that is as large as your home. However, if left undetected and repaired, even a small slab leak can undermine the soil that supports your home’s foundation. When this occurs, there is sure to be damage to the structure of your house, including the walls and floor. Leak detection experts use the latest tools and technology to locate even tiny water leaks via thermal imaging, sound amplification tools, and temperature fluctuation. The type of leak and its location will dictate how the leak is repaired.


Because a slab leak is under your home’s foundation, you are sure to be wondering how you would ever know there is a problem. It is rare to see any sign of water oozing up through your floor; however, it is possible in the case of a severe leak. More subtle indications of a slab leak include:

  • Noticeably warm or cool areas on the floor
  • The sudden appearance of cracks in the walls of your home
  • Cracks in the foundation of your home
  • Unexplained moisture along the foundation of your home
  • An excessively high water bill
  • The sound of running or dripping water in your home
  • Unexplained mold or mildew appearing in your home or on the exterior walls near the foundation
  • Your home’s water meter is constantly in motion
