Professional Void Fill With Polyurethane Injections

Void Fill Services in Alabama

If you’ve noticed concrete slabs sinking, cracking, or shifting around your home, the problem might be deeper than it looks. Voids, empty pockets beneath the concrete, can form over time due to soil erosion, water runoff, or improper compaction during construction. These hidden gaps can cause serious structural issues if not addressed quickly. At Southern Dry, we offer professional void fill services to stabilize your concrete and restore long-term safety and support.

Void Under Concrete

What Is Void Fill?

Void fill is the process of injecting material beneath a concrete slab to fill in the empty space between the slab and the soil below. These voids are often created by natural soil movement, erosion from water drainage, or even pests tunneling through the ground. Once the soil underneath weakens or washes away, the concrete above has no support, causing it to crack, tilt, or settle unevenly.

At Southern Dry, we use advanced polyurethane foam injection to fill these gaps. The foam expands as it cures, creating a dense, supportive base that lifts the slab and locks it into place. It’s a fast, clean, and long-lasting solution for driveways, sidewalks, patios, porches, pool decks, and more.

Filling a Void Under Concrete

Why Void Filling Matters

Leaving a void untreated can lead to bigger and more expensive problems down the road. As the unsupported concrete continues to sink, cracks can worsen, tripping hazards can form, and structural stress can build up in surrounding areas. In some cases, water can pool in the sunken areas, creating slip risks or further weakening the foundation.

Void fill helps stop that damage in its tracks. By restoring the support beneath your concrete, you protect your home and improve safety, all without the mess and cost of tearing out and replacing the slab.

Why Our Method Works Better Than Mudjacking

Not all void fill methods are the same. Traditional mudjacking involves pumping a heavy cement slurry beneath the slab to fill gaps. While it can lift concrete, mudjacking adds significant weight to already unstable soil. Over time, that weight can cause the slab to sink again, especially in areas with poor drainage or loose ground.

At Southern Dry, we use polyurethane foam injection instead. This modern approach is lightweight, fast-curing, and more precise. The foam expands to fill voids completely without putting added stress on the soil. It’s also water-resistant, so it won’t wash away or break down over time the way some mud-based materials can.

Polyurethane void fill offers a cleaner process, longer-lasting results, and minimal disruption to your property. That’s why more homeowners across Alabama are turning to this method instead of old-fashioned mudjacking.
