The Complete Guide to Slab Leaks

Get the Scoop on Slab Leaks 

Slab leaks are among the worst plumbing problems that homeowners run into, but most people never learn what a slab leak is until they have to deal with it themselves. In this blog post, our plumbing experts share valuable insight on slab leak detection, why slab leaks are dangerous, and what can be done to fix them. 

Homeowners might first notice signs of a slab leak in the form of a wet spot on the carpet or a puddle forming on the floor seemingly randomly. The floor might be warm to the touch, and the carpet may become discolored in the spot where the leak is. When serious water damage has already occurred due to a foundation leak, the first indicator of the leak may be a foul or moldy smell coming from the walls or floor. If homeowners notice one of these signs, they should call a professional before any damage worsens. 

What is a Slab Leak?

What is a slab leak? The “slab” is the layer of solid concrete foundation on which the home sits. The plumbing lines go directly under the slab on the first floor. 

Most slab leaks are caused by soil expanding around the home’s foundation. The phenomenon called expansive soil shift is common, with an estimated 25% of homes reporting damage from expansive soil. Expansive soil absorbs water and expands, pressing inwards on the foundation until it crumbles. Homeowners may be able to see which direction the soil shifted by looking at the plants outside of the home. 

Slab Leaks Can Be Dangerous

Slab leaks can cause the same type of problems as other plumbing leaks, such as corrosion, loss of water pressure, or a spike in utility bills. What makes slab leaks different than other plumbing leaks is additional potential consequences. The leak's location is what makes it detrimental to the integrity of the structure. 

One of the worst things about a slab leak is that by the time the homeowner notices it, it is usually too late to prevent water damage. Sometimes it takes weeks or even months for the homeowner to notice the leak, and mold usually starts to grow around day three. Homeowners should immediately schedule slab leak repair after a foundation leak is detected to stop water damage in its tracks. 

How to Address the Problem plumber

It is important to address the problem of a slab leak as soon as possible before serious damage can occur. The weakened foundation may continue to crack as long as the water pours out into the soil beneath it. Slab leak repair is a complicated task that requires the hands of an experienced professional plumbing contractor. 

Perhaps the hardest part about repairing a slab leak is figuring out how to get through the concrete foundation to reach the water pipes for repair. In some cases, it may be easier to reroute the water flow by adding new pipes instead of digging down into the foundation to repair the old pipes. The other option is to break through the concrete slab to fix the plumbing and re-do the foundation afterward.
