Fill Hidden Voids • Stabilize Weak Soil • Stop Settlement • Protect Your Concrete

Voids under concrete form when the supporting soil washes out, collapses, or shifts. These empty pockets cause slabs to sink, crack, or become unstable — and the problem only grows with time. PolyFix Inc. fills underground voids using high-density polyurethane foam, restoring solid ground support and preventing future settling without tearing out your concrete.

Why Voids Form Under Concrete

Voids are extremely common in North Texas due to soil movement and water-related erosion. The most common causes include:

Shrinking and swelling clay soil
Water runoff washing away soil
Plumbing or drainage leaks
Settlement from poor soil compaction
Burrowing animals beneath slabs
Heavy rain creating washout tunnels
Soil collapsing under heavy loads
Groundwater shifts near foundations and pools

Once a void forms, the slab above it loses support and begins to dip or crack.

Common Signs You Need Void Filling

You may have voids under your concrete if you notice:

Hollow or “empty” sounds when walking across slabs
Visible gaps under concrete edges
Slabs rocking or moving when stepped on
Sudden dips, cracks, or uneven sections
Soil disappearing near porches or patios
Washout areas forming after heavy rain
Driveway or walkway sections sinking in one spot
Slabs pulling away from steps, walls, or pool edges

Voids grow quickly and lead to bigger structural problems if left untreated.

If you have voids forming under your concrete, nearby areas like your driveway, walkways, or porch may also be at risk of settling. We also handle concrete repair and slab leveling if your concrete has already shifted.

 Trustindex verifies that the original source of the review is Google. Very happy with the leveling of our front walkway. Brandon and Cody communicated step by step the process and checked with me to make sure I was happy with the results. They did a great job. The price I paid was very reasonable and a 1/3 of what the others had quoted. Overall, very easy to work with from start to finish.

 Trustindex verifies that the original source of the review is Google. I had a very uneven sidewalk. There were areas that were higher than others. Most were caused be tree roots. Many companies would not do this job because it is too small. However, PolyFix made an appointment and arrived on time. Brandon and Cody explained and let me watch the procedure. Really nice guys who are good at their jobs. The whole process took about an hour and the results are great. I cannot rate them any higher!

 Trustindex verifies that the original source of the review is Google. We recently had PolyFix help us raise our driveway.  They did a fabulous job, from the initial visit to evaluate and estimate to the actual execution.  Kudos to David, their crew chief on-site-he was really great tow work with.  I highly recommend this company.

 Trustindex verifies that the original source of the review is Google. Very professional and talented group, I highly recommend them. Our pool deck had dropped several inches on one side and they were able to lift it back to its original elevation in a couple hours. Very personable team and easy to work with.

 Trustindex verifies that the original source of the review is Google. I can't be more pleased with the job PolyFix did on lifting a sinking section of my warehouse floor due to a water leak. The floor had dropped nearly 1.5" in one area leaving a visible gap between an interior wall the the floor. PolyFix was able to return the floor almost to the original height and got the job done in 1/2 a day with minimal mess, and for a reasonable price for this size of job.

 Trustindex verifies that the original source of the review is Google. PolyFix did a great job on lifting my driveway. I called on a weekend and left a message and figured they would call me back on Monday, but I received a call back shortly after. I spoke with Bill and  he was very clear in answering all my questions and most importantly he was honest about other alternative services that he didn't even provide. David came out and did a fantastic job and even explained to me the process while he was doing it. David was very thorough and extremely professional from start to finish. I highly recommend PolyFix to anyone that needs driveway lifting.

Our Fix: Polyurethane Foam Void Filling

PolyFix Inc. uses expanding polyurethane foam to fill voids beneath concrete slabs, porches, floors, pool decks, and seawalls. This foam travels deep into voids and weak areas, expands to fill empty space, and compacts the surrounding soil.

Our process:

Drill small ⅝″ injection holes
Inject expanding polyurethane foam
Foam moves through voids and fills empty pockets
Soil is strengthened and stabilized
If needed, the slab is lifted during the same process
Injection holes are patched cleanly

This provides long-lasting stability without excavation or concrete replacement.

Benefits of Polyurethane Void Filling

Stops ongoing soil washout
Fills deep voids and hidden gaps
Prevents slabs from sinking or cracking
Stabilizes the soil for long-term support
Lightweight foam won’t add pressure to weak ground
Fast, clean, and non-invasive
Saves up to 70% vs. replacing concrete
Works even in wet or waterlogged areas
Eco-friendly foam (40%+ recycled/renewable content)
Ideal for residential slabs, pool decks, porches, garages, and seawalls

A smart way to protect your concrete and prevent future structural damage.

Void Filling – Frequently Asked Questions

Q. How do I know if I have a void under my concrete?

Common signs include hollow sounds, visible gaps, rocking slabs, or sudden dips. Our inspection can confirm if voids or soil washout are present beneath the slab.

Q. Is void filling the same as concrete leveling?

Not always. Void filling stabilizes the soil and fills empty pockets. If the slab has already dropped, we can also lift it during the same appointment using polyurethane foam.

Q. Can your foam fill large or deep voids?

Yes. Our foam expands through large cavities, tunnels, and deep pockets of missing soil. It’s designed to travel and fill irregular shapes underground.

Q. Will the repair stop future sinking?

Yes. Filling voids stabilizes the soil and prevents the slab from losing support again. This greatly reduces the chance of additional settling.

Q. Is this safe around pool decks, porches, or steps?

Absolutely. We routinely fill voids under pool decks, porches, patios, steps, walkways, and driveways without damaging surrounding structures or surfaces.

Q. How long does void filling take?

Most void filling projects take 1–2 hours. The foam cures quickly, and the area is typically ready for use shortly after the work is completed.

Q. Do you offer a warranty for void filling?

Yes. All void filling and concrete raising work is backed by our 2-year warranty. If covered settlement occurs within the warranty period, we will evaluate and address it.
