Common Causes & Signs That You Have A Slab Leak



Minor earthquakes are simply a part of life. However, this reality can wreak havoc on the foundation and structural integrity of any home. With newer developed homes built on a slab of concrete, it is not uncommon for homeowners to run into slab leak problems. These slab leaks can strike on hot or cold water lines and can appear on any drain line from any home appliance that uses water. It is important for homeowners to know both what causes slab leaks and how to identify one.


What is a Slab Leak?

A slab leak is an industry term used to describe a leak that has developed in the copper water lines running below the concrete foundation of your home. When these same leaks are above ground, in the wall or ceiling, they are known as pinhole leaks. Such leaks are often a result of long-term corrosion to copper pipes.


Slab leaks can be found either on the pressure side or the drainage side of your foundation. If the slab leak is on the pressure side of the drains, it can typically be unearthed prior to triggering a lot of destruction. While these leaks are usually found quickly, they can cause significant damage. Leaks on the drainage side can be considerably more veiled, making them trickier to spot. They can leak for ages, showing no external indication. Slab leaks can make your foundation collapse. To stop this from happening, the plumbing must be examined frequently.


Since slab leaks are not clearly visible to a homeowner, they can often go undetected for long periods of time. Leaving a potential slab leak unattended can lead to much larger problems, such as mold damage and termite infestation. With that said, you can look out for more subtle signs that may indicate you have a slab leak.
