Most homes and buildings in Texas are built on concrete slabs — providing strong, level surfaces for structures to rest on. These slabs typically range from 4 to 20 inches in thickness and are critical for floors, ceilings, and exterior areas.

However, when water or sewer lines underneath a slab break or leak — often due to soil shifts, faulty pipe installation, or erosion — it can cause significant structural damage. Slab leaks require immediate attention from experienced, licensed professionals to prevent costly repairs down the road.

At DFW Foundation Repair, our Master Technicians specialize in identifying and repairing slab leaks efficiently and effectively. Using non-invasive camera inspections, we locate the source of the problem and deliver high-quality repair solutions you can trust.

Warning Signs of a Slab Leak

An unnoticed slab leak can cause tens of thousands of dollars in damages and compromise the safety of your entire home. It’s important to recognize the early warning signs and contact us immediately if you notice:

• Cracked or Uneven Floors: Leaks beneath the slab can cause the foundation to shift, buckling your tile, laminate, or hardwood flooring.

• Mold Growth: Water seepage can spread into walls and floors, creating ideal conditions for harmful mold.

• Musty or Sewage Odors: Damp, unpleasant smells may indicate a water or sewer line leak beneath the slab.

• Raised or Sunken Floors: Foundation cracks caused by leaks can create visible bumps, rises, or sinking areas on your floors.

• Unusual Water Sounds or High Bills: Hearing running water when no faucets are on or a sudden spike in your water bill can point to a hidden leak.

Our Slab Repair Process

We follow a proven, three-step approach to restore your slab foundation to optimal condition:

Step 1: Access and Diagnose the Problem

First, we create an access point to reach the damaged area — either by tunneling from the perimeter or jackhammering through the slab. Our technicians then thoroughly inspect the issue to determine its cause.
Once identified, we provide you with a detailed diagnosis and a FREE estimate outlining the best repair plan for your foundation.

Step 2: Press the Piers and Raise the Slab

Next, we install pressed concrete piers — solid cylinders roughly 12 inches long and 6 inches wide — beneath the foundation. Using a hydraulic jack, we drive the piers deep into the ground, one atop the other, until reaching “absolute refusal” (the point where further movement is impossible).
This process creates a stable support system, transferring your home’s weight onto stable soil strata. Once the piers are set, we use hydraulic jacks (each capable of lifting 25 tons) to carefully raise the slab back to its original level, under the supervision of a seasoned Foundation Repair Manager.

Step 3: Shimming and Backfilling

After leveling, we lock the foundation in place using steel shims (“slice-of-bread” sized plates) and concrete blocks for precision control of elevation.
Finally, we refill all holes with the displaced soil, ensuring proper compaction and allowing the ground to settle naturally over time.
