Al’s Plumbing Finds & Fixes Slab Leaks
There can several causes of leaks below a concrete slab, the most common reason in DFW is the clay soil below your foundation. Clay expands when wet and shrinks when dry, and moisture levels are continually changing.
Heaving and settling soil below the slab puts unacceptable amounts of pressure on the concrete, causing the concrete to shift, heave and crack. Underground plumbing is connected to the slab in several places. When movement of the slab occurs, breaks in the pipes (both water-supply and waste-lines) can occur.
Al’s Plumbing repairs any type of slab leak in any location. Al’s does not cut through slabs, we tunnel under the home and do the work from below the slab. The slab remains unaltered and as it was designed and built to perform.
Homes built since around 1990 have a Post-Tension Slab. This type of slab cannot be cut due to safety risks and undermining the integrity of the slab if one of the cables inside the slab becomes severed.
Symptoms of slab leak
Why is a Slab Leak Dangerous
The health concerns caused by a slab leak are nothing to take lightly. Excessive water leads to mold. Breathing in mold for an extended period of time can lead to respiratory-health issues. If you find dampness or mold under within your carpet and / or carpet-pad, contact a slab leak detection specialist to locate and repair the leak right away.
A slab-leak causes the moisture level in the clay below your home to continually increase. The expansion of the clay near the leak will cause far more pressure on the slab than it was designed to accommodate, resulting in heaving and cracking of the slab at the site of the leak if left unrepaired for an extended period of time.

Finding & Confirming a Slab Leak
To do this properly, electronic detection tools are required. If you suspect a leak, find leak-detection specialists like Al’s Plumbing. We will confirm you have a leak before digging into concrete. The location of the leak can easily be different that one would suspect without electronic detection to find it.
Signs of a Slab Leak
AL’S TIP: You can confirm a slab leak by watching the water meter while no water is turned on.
Did you suddenly have a spike in your water bill? If nothing in your consumption patterns has changed, you likely have a new slab leak
Use this simple test. With all water faucets in the house turned off, look a your water meter to see if it’s showing usage. If everything inside is turned off, the meter will not be showing usage.
If every faucet is turned off and you see usage on the meter, you have a water-supply line which is leaking.
AL’S TIP: It is also possible that a waste line is leaking under the slab. This is harder to spot. If you have wet soil along some portion of the outside of your home when everything else is dry, you may have a waste-line (sewer) pipe leak.
Why would you suddenly have a waste-line leaking? The most likely cause is failed cast-iron sewer pipes under the slab. Cast-Iron pipes typically rust from the inside out, but also can rust from the outside due to contact with soil under your home.
Helping Prevent a Slab Leak
You can easily and dramatically decrease the changes in soil moisture-level. Here’s how:
- If you don’t have them, add rain-gutters. If you have gutters, ensure the downspouts drain 2 feet or more further the lawn and away from the house (using an extension). Without gutters, all water from the roof drains directly at the edge of the home’s foundation, causing extensive changes in moisture levels. There are many types of gutter down-spout extensions. They all serve the same purpose of getting the down-spout water further from the home’s foundation.
- “Water” your home’s foundation in summer with a “weeper / soaker” hose set to run every other day for 20 or more minutes. You can also buy a moisture-meter at most home stores.All brands of Weeper / Soaker hoses work essentially the same.
