Are you experiencing cracks and shifts in your concrete? Then void-filling may be the answer. Not only does uneven concrete look unappealing, but it can be unsafe, leading to tripping hazards and poor drainage.
If you have suspicion that there are gaps or voids under your concrete slabs, then it’s time to schedule an appointment for void-filling.

What is Void-Filling?
Void-filling is the process of injecting a certain specialized foam underneath concrete slabs to fill the voids and empty spaces and better support the concrete. This process is often done after the ground beneath the concrete shifts has subsided. When this occurs, the concrete doesn’t have the support it needs, leading to cracking or an uneven surface.
At Polyfoam Solutions, we use high-density polyurethane foam to fill up those gaps, which then hardens and reinforces the concrete. This is a quick, clean, and effective solution for dealing with problematic concrete and preventing future issues.
Why Does Void Formation Happen?
Soil naturally settles over time and becomes more compact. This tends to happen more with newer housing developments or buildings where the construction has disturbed the soil and concrete is placed on top. If the soil has not been given the proper time or treatment beforehand, it can cause problems in driveways, sidewalks, or foundations.
Once a home is built and the surrounding ground begins to compact, then the small air gaps expand and show up beneath the concrete surfaces. Any heavy weight that is on top – like foot traffic, vehicles, or even time – cracks start to form, which can lead to the slabs sinking, shifting, and creating unsafe conditions.

The Cost of Waiting
It can be a temptation to not deal with early signs of cracking or concrete sinking. After all, it’s just a small crack – what harm is it going to do?
But this is a risk. Because a lot of the issues are under the surface and out of sight, you won’t know the extent of the damage or problem, which means it could get worse. As the voids continue to grow, repairs become more extensive, meaning costly expenses in the long-run and sometimes even full concrete replacement.
That’s where we come in. At Polyfoam Solutions, we give you a cost-effective solution that is quick, easy, and helps prevent further damage. Void-filling is a reliable and long-lasting choice that helps deal with the problem at the source, protecting both your property and your wallet.
Signs You Might Have a Void Under Your Concrete
It’s important to look for the signs of voids so that you can identify if you need void-filling and address it quickly. Here are some common signs to keep an eye out for:
- New construction in the area
- Pooled water or poor drainage around concrete surfaces
- Concrete slabs that have become uneven or shifted out of alignment
- Cracks appearing in your patio, sidewalk, or driveway
- Sections of concrete that feel hollow or sound “empty” when tapped
If you begin to notice any of these issues, then give us a call. It’ll be cheaper and safer to deal with these problems early on and schedule void-filling.
