You’ve probably heard of slab leaks and the high expense they cause. A slab leak is a plumbing and insurance term used to refer to leaks that have occurred in the water lines that run under the concrete slab that makes up your home’s foundation, hence the name. The constant flow of water causes damage to your foundation, and over time, the damage can extend to the surface of your foundation. When a leak has reached the surface of the foundation, it’s referred to as a pinhole leak. Repairs must be made as soon as possible, otherwise the leak can compromise your entire foundation, and the cost to repair the foundation increases as the damage becomes more extensive.

How Do I Know I a Slab Leak?
Most people don’t realize they have a slab leak until cracks have appeared in their foundation. By this time, it’s already too late to get off without an expensive repair bill. However, if you know what to look for, you can detect a slab leak before the damage is done. Here are some clues to look for:

  • Unusually cool or warm spots on floors– Not a concern by itself, but if you feel wetness near these spots, you should have your plumbing checked. You should not be feeling any cold or warm spots on your floor.
  • Unexpected wet spots on your floor– If you feel any wet spots on your floor that you cannot explain, contact a plumber immediately. Don’t worry about wasting the plumber’s time. You might end up saving yourself a ton of money.
  • Sudden increase in water bills– If your water bill shoots up unexpectedly, it’s almost certainly a sign of trouble. A small price hike is nothing to worry about. It’s large price hikes that are cause for concern. Water leaks can waste a surprising amount of water, and whether you use the water or not, you’re being charged for it.
  • Sound of running water– If your faucets are off, but you still hear the sound of running water, that could also be a sign of a slab leak. Call a professional plumber immediately. You might be able to catch the leak before it does serious damage.

What Causes Slab Leaks?

There are a few things that can cause slab leaks. Simple corrosion, friction breaks caused by excessive vibration, manufacturing defects and excessive pressure caused by Human error or ground shifting can all cause slab leaks. The best prevention is to detect the problem early, if possible.


Repairing a slab leak is a time-consuming process that begins with a quick meter check. If movement is detected, we will check your system’s water pressure. If the pressure test fails, we then proceed with an acoustic inspection using electronic equipment that’s specially designed to listen for signs of running water. This helps us localize the problem. Once the problem has been localized, a special microphone is used to further pinpoint where the problem has occurred.

After the leak has been located, we use a signal generator and receiver to find out where the lines are run. Then we expose both ends of the line that’s causing the problem, open a section of the slab and cap the line until it has been completely repaired.
