Slab Leak Detection and Repair: A Comprehensive Guide

It’s a homeowner’s worst nightmare: a slab leak. Not only is it frustrating to have water leaking under your foundation, but it can also be costly to repair. Luckily, with the right knowledge and help from a skilled plumber, detecting and repairing a slab leak can be done efficiently and effectively.

In this article, we will cover everything you need to know about slab leak detection and repair. We’ll also discuss how to find a trustworthy plumber near you and what to do if your home’s foundation is post-tensioned.

Understanding Slab Leaks

First, let’s talk about what a slab leak is. A slab leak occurs when the pipes running under your foundation break or malfunction, causing water to leak into the concrete slab. This problem is most common in homes that are built on a concrete slab, but it can also happen in homes with a raised foundation.

There are several signs that you may have a slab leak, including:

• The sound of running water when all faucets are turned off
• Standing water around your foundation
• A sudden increase in your water bill
• Uneven, warm, or moist flooring

As with the image above, if you have hardwood flooring, it will be undeniable if you are having a slab problem. 

If you suspect you have a slab leak, the next step is to find an experienced plumber near you. A quick Google search for “leak detection near me” should yield a list of local plumbers who specialize in leak detection and repair. Be sure to read reviews from past customers and check their credentials before hiring them.

Determining If Your Home Has a Post-Tension Slab

One important thing to consider before detecting and repairing a slab leak is whether or not your home’s foundation is post-tensioned. A post-tensioned slab is a type of concrete foundation that uses steel cables to reinforce the concrete. It’s a popular method of construction because it allows for larger, more open spaces without the need for additional support columns.

It’s important to know if your home’s foundation is post-tensioned because the method of repair for slab leaks is different from traditional concrete foundations. If a post-tension slab is repaired incorrectly, it can destabilize the entire foundation.

To determine if your home has a post tension slab, you can look for signs, such as:

• A thickened edge around the perimeter of the foundation
• Steel cables running through the concrete
• A slab thickness of less than 4 inches
• A stamp in the garage

If you’re not sure whether your home’s foundation is post-tensioned, it’s best to consult with a professional plumber or a structural engineer. They can properly assess the situation and recommend the correct method of repair.

Slab Leak Detection

Once you’ve determined that you have a slab leak, the next step is to detect where the leak is coming from. This can be done using various methods, including:

Visual inspection:

The licensed plumber will visually inspect the foundation for signs of water damage or leaks.

Pressure testing:

The plumber can test the water pressure to determine if there is a leak.

Once the plumber has determined the source of the leak, they can begin the repair process.

Repairing a Slab Leak

Repairing a slab leak can be a complex process, and it’s important to hire a skilled plumber to ensure the repair is done correctly. The method of repair will depend on the location and severity of the leak, as well as the type of foundation.

For traditional concrete foundations, the plumber will typically cut into the foundation to remove and replace the damaged pipe. For post-tension slabs, the process is a bit more complicated. 

Finding the Right Plumber Near You

When it comes to slab leak detection and repair, finding the right plumber near you is crucial. Look for plumbers with experience in leak detection and repair, as well as good reviews from past customers. Don’t be afraid to ask for references or to check their credentials before hiring them.

Additionally, make sure the plumber you choose has experience working with post-tension slabs if your home’s foundation is constructed using that method. It’s better to be safe than sorry when it comes to repairing the foundation of your home both for your safety and for the safety of the plumber working in your home.
