When concrete slabs begin to sink or settle, it can lead to structural problems that affect both the safety and aesthetics of your property. Fortunately, there is a highly effective solution: concrete lifting with foam. But what kind of foam is used for this task?
The expert choice for concrete lifting is high-density polyurethane foam. At TerraFirma, we use PolyLevel, which is a cutting-edge method designed to lift and stabilize sinking concrete slabs.
How Does PolyLevel Work?
PolyLevel uses a two-part urethane formula that, when injected beneath the concrete, reacts and expands to fill any voids or gaps under the slab. As the foam expands, it pushes the concrete upward, stabilizing it to its original position. This process is incredibly effective at lifting heavy concrete structures without causing additional damage or requiring major disruption to your property.

Why Polyurethane Foam?
Polyurethane foam is the ideal material for concrete lifting for several reasons:
- High Density: The foam’s density allows it to support significant weight, making it perfect for heavy concrete slabs, including sidewalks, driveways, and even large concrete structures like floors and foundations.
- Quick and Efficient: The foam expands and cures quickly, which means the lifting process can be completed in just a few hours, minimizing downtime and disturbance to your property.
- Long-Lasting Stability: Once in place, the foam provides a permanent solution to sinking concrete. It resists moisture and won’t break down over time, ensuring long-term stability.
- Non-Invasive: Unlike other traditional methods that require tearing up the concrete, the PolyLevel method is minimally invasive and involves only small, strategic injection points to do the job.
The Benefits of Concrete Lifting with Polyurethane Foam
- Cost-Effective: Since it’s faster and requires fewer resources compared to traditional methods like full concrete replacement, it is a more affordable option.
- Environmental Benefits: Polyurethane foam is environmentally friendly and doesn’t produce excess waste, unlike some other concrete repair methods.
- Long-Term Performance: PolyLevel’s high-density polyurethane foam ensures that your concrete remains level and stable for years, offering peace of mind.

If you’re dealing with sinking concrete in Portland, Hillsboro, Beaverton, or Tigard, the high-density polyurethane foam solution provided by PolyLevel could be just what you need to restore your surfaces. Not only is it an effective method, but it’s also a reliable, long-term solution to concrete settlement problems.
