Everything You Need to Know About Slab Leaks

According to the National Association of Home Builders, nearly 96% of homes built in California rest on concrete slab foundations. These slab foundations are responsible for bearing the entire weight of your home, keeping groundwater out, and acting as a barrier for all potential vapors that could seep into your home. For all of these reasons, you’ll want to make sure that you are keeping your foundation as solid and stable as possible. One of the most common reasons concrete slab foundations fail is because of slab leaks. Keep reading to learn more about:

  • what slab leaks are;
  • what causes them
  • what signs to look for; and
  • what to do if you find one.

What is a slab leak?

A slab leak is a term that is used to describe a leak that has developed in the water lines running beneath the foundation of your home. There are two types of slab leaks: a pressure side leak and a drainage side leak. Pressure side leaks are much easier to detect and therefore don’t usually cause a lot of damage; however, because drainage side leaks can go undetected for long periods of time, they can be incredibly destructive to your property.

What causes a slab leak?

Poor Construction

If your home's pipes were installed incorrectly when the house was built, you’ve essentially been set up for a slab leak. Often, construction materials get banged up before or after they're installed in a home. When it's your pipes that are dented or installed incorrectly, you could end up with severe damage down the road.

Water Chemistry

The chemical composition of your water can cause significant pipe corrosion. Your pipes could be in danger of premature corrosion if your water is too acidic, otherwise known as “hard” water, or too alkaline, otherwise known as “soft” water.

For reference, your water should be at a neutral level, between a 6.5 and an 8.5 on the pH scale. You can easily check this with pH indicator strips or by calling yourlocal plumber!

Environment

In California, we are no strangers to earthquakes which, if strong enough, can cause the ground around your home—and sometimes even your foundation itself--to shift. Even common soil erosion can have the same effect. When this happens, pressure spikes around your pipes could eventually cause them to burst.

Additionally, if your pipes were built with little room for expansion when they were placed within concrete, gravel or other pipes, the grinding of materials could cause your pipes to wear down and eventually burst.

What are the signs of a slab leak?

There are quite a few signs that could alert you to the possibility of a slab leak. A few of them include:

  • Sudden spikes in your water bill
  • The constant sound of running water, even when your pipes aren’t in use
  • Moisture under carpeting
  • Standing water in your lawn or around the perimeter of your home
  • Low water pressure

If you notice any of these signs, you could potentially have a slab leak or another plumbing issue. It’s time to call your plumber right away.
