How Does Concrete Lifting Foam Work?
Injection Process Explained
The process begins with small holes, typically about the size of a dime, being strategically drilled into the affected concrete slab. These holes serve as entry points for the polyurethane foam. Unlike traditional methods requiring extensive and invasive excavations, this minimally invasive approach keeps your property pristine.
Next, a specialized injection gun introduces the foam mixture into these holes. The polyurethane resin and foaming agent are mixed on-site, ensuring optimal consistency and performance. This mixture is carefully injected beneath the sunken slab.
Expansion and Lifting of Concrete Slabs
Once injected, the polyurethane foam begins to react. It expands, filling the voids and empty spaces beneath the concrete slab. This controlled expansion exerts uniform pressure, gently lifting the sunken or uneven concrete to its original level. It’s like giving your concrete a much-needed lift without the need for heavy equipment or significant disruptions.
The precise expansion process allows technicians to control the amount of lift required. This precision ensures that the concrete is brought back to its ideal position, preventing future settling or sinking.

Advantages of Using Concrete Lifting Foam Over Other Methods
Traditional Mudjacking
Differences in Process and Materials
Traditional mudjacking, or slabjacking, involves drilling large holes into the sunken concrete and then pumping a mixture of soil, water, and cement (the “mud”) beneath the slab to lift it. This process relies on the heavy weight of the mud to push the concrete back into place.
On the other hand, concrete lifting foam is a much less invasive process. It uses smaller holes for injection, and the foam itself is lightweight. Instead of heavy mud, it relies on the expanding properties of polyurethane foam to lift the concrete.
Advantages of Foam Over Mud
- Weight: Foam is lightweight compared to the heavy slurry mixture used in mudjacking. This difference in weight is a game-changer. Foam exerts less pressure on the already compromised soil underneath your concrete, reducing the risk of further settling and damage to your property. Heavy mud can exacerbate the problem by adding more stress to the weakened subgrade.
- Precision: Foam offers unparalleled precision. When injected, it expands uniformly and can be controlled with precision. This means that only the areas needing correction are lifted or leveled. Conversely, mud can be less precise and may result in overcorrection or uneven lifting.
- Speed: Foam is the hare to mud’s tortoise. Foam lifting is a faster process, with minimal curing time required. You can expect to resume regular use of your concrete surfaces in a fraction of the time it would take with mudjacking. This speedy turnaround minimizes disruption to your daily routine.
Replacement of Sunken Concrete
Time, Cost, and Labor Comparisons
Completely replacing sunken concrete is a time-consuming, labor-intensive, and costly endeavor. It involves breaking up and removing the existing concrete, preparing the subbase, pouring new concrete, and waiting for it to cure. This can take days or even weeks.
Concrete lifting foam, in contrast, can often be completed within a matter of hours, depending on the project’s scope. It requires far less labor and significantly reduces downtime.
