Slab Leak Damage: What to Watch Out for & How to Repair

A slab leak is a water leak that occurs beneath the concrete foundation of a home. While a small leak may not cause any damage, a larger leak can cause serious problems, including cracked foundations, damaged floors and walls, and mold growth.

In this article, learn more about what you should watch out for to know if you have slab leaks and what things you can do to repair them.

What Are Slab Leaks?

Slab leaks occur in the water and sewer lines that run beneath concrete slabs. These leaks can cause extensive damage to your home and pose a serious health hazard. Slab leaks are often caused by faulty plumbing, poor construction, or ground movement.

Slab leaks can occur in both fresh water and sewer lines. A freshwater leak can cause your water bill to increase, as well as cause water damage to your home. A sewer leak can contaminate your drinking water and cause your home to smell like sewage. Sewer leaks can also lead to the growth of mold and mildew.

What Are the Signs of a Slab Leak?

It’s important to be aware of the signs of a slab leak so you can take action as soon as possible. Here are six warning signs that you may have a slab leak:

  1. Unusually High Water Bills — If you’ve noticed your water bills increasing for no apparent reason, it could be due to a slab leak. Water leaks can quickly use up a lot of water, leading to a spike in your bill.
  2. Water Pressure Issues — A sudden drop in water pressure can also signify a slab leak. If you notice that your water pressure is lower than usual, it’s worth checking for leaks.
  3. Cracks on the Floors and Walls — If you notice cracks on your floors or walls, it’s possible they’re caused by a slab leak. As water leaks from the slab, it can cause the surrounding areas to crack.
  4. Water Stains — Water stains on your walls or floors could be another sign of a slab leak. If you see water stains that you can’t explain, it’s worth checking for leaks.
  5. Mold — Mold growth can be another sign of a water leak. If you notice mold in your home, it’s important to investigate the cause.
  6. Strange Smells — If you notice strange smells from your floors or walls, they may be caused by a slab leak. These smells are usually the result of sewer gases escaping from the leak.

If you’re dealing with a slab leak, there are a few different ways to fix the problem. 

1. Repair
