What causes a leak in the slab?
Before we discuss how to tell if you have a slab leak and what a slab leak detection is, let’s explain what a slab leak for those is that those that may not understand. The slab is what they build your home on, the concrete foundation. The home builder will run sewer and water lines before they pour the slab.
Over time, those lines will deteriorate, break or leak, and that is what results in a slab leak. Slab leaks also result from a chemical reaction between the metal and the soil or faulty installation. Many times, it is the soil shifting under the slab, a common problem in this part of the southern part of the United States.
How serious is a slab leak?
A slab leak may start out as a minor matter, but left unattended, it can cause serious problems inside and outside of your home. Often, before a homeowner realizes they have a slab leak, they have paid for it financially through higher electric and water bills. If you realize you have unexplained higher utilities, a professional slab leak detection can be an enormous help. When a slab leak is left unattended, the following issues can happen:
- Carpeting and flooring ruined: When water has been seeping through the floor, it will begin to weaken the flooring, cracking tile, saturating the floors, and soaking the carpeting.
- Musty odor: A slab leak left unattended will create musty odor into your home. If the slab leak is from the sewer line, your home will overtake by the smell of raw sewage.
- Mold growth. As the water seeps into your home from the foundation, the drywall and wood frame will absorb that water where it will grow mold and other bacteria. These growths are harmful to the health of you and your family, even the family pets.
Now that you know what can happen inside your home from without slab leak detection or repair, let’s review what happens in the exterior.

- Sound of rushing water: If you hear water rushing underneath the flooring, you don’t need any slab leak detection equipment to know you have a slab leak.
