Lift Your Sinking Concrete with PolyLevel® in Nebraska, Missouri, Colorado, Iowa & Kansas

Do you have a sinking pool deck, uneven sidewalks, or a sunken, cracked driveway? Uneven, cracked concrete can make a significant impact on your home's curb appeal and value. Plus, sinking concrete can cause liability issues as a serious falling hazard. That is why Thrasher Foundation Repair provides a fast and reliable way to lift and stabilize sinking, cracked concrete of all kinds with PolyLevel®. Our concrete leveling system is a lightweight but durable high-density polyurethane foam developed by our sister company Supportworks - and is only available to an exclusive network of foundation and concrete repair contractors.

The expanding polyurethane foam expands to lift and support slabs without adding extra weight to the load-bearing soils underneath. It is also waterproof, which means it won't wash out or dry out like traditional mudjacking materials. Even better, PolyLevel® is environmentally friendly with no harmful chemical leaching. PolyLevel® also compacts the soil around slabs, creating a stable environment that will ensure the driveway, patio, pool deck, and other slabs remain level for years to come.

When you choose to protect your slabs with the PolyLevel® concrete leveling system, you can rest easy knowing that they will look great and function well for years to come. Plus, you can have even more confidence knowing you have a five-year warranty!

Frequently Asked Questions

• What types of concrete surfaces can be leveled?

  Almost any concrete slab that sits on top of soil can be lifted and leveled with PolyLevel. This includes traditional areas - concrete driveways, sidewalks, patios - as well as other concrete areas around your home or office, such as your pool deck or front stoop.

• What's the process like for leveling concrete?

  PolyLevel polyurethane foam is pumped beneath concrete slabs through tiny ports about the size of a penny. Initially, PolyLevel flows like water, filling even the smallest cracks and crevices in the soil. It quickly expands and hardens, lifting the concrete slabs above it and compressing the soil around it at the same time. PolyLevel cures quickly, allowing your concrete to be used normally just 15 minutes after installation.

• What materials do you use to level concrete?

  At Thrasher, we use PolyLevel polyurethane foam to lift and level concrete. PolyLevel is a lightweight, strong high-density polyurethane foam that lifts and supports concrete slabs without adding weight to the soil beneath. It's waterproof, so it won't wash out or dry out like traditional mudjacking material. It's environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete leveling with PolyLevel expanding foam not only raises concrete slabs, but also compacts the soil around it, creating a stable environment that will ensure that your driveway, patio or pool deck remains level into the foreseeable future.

• What causes concrete to sink or crack?

  Driveways, walkways and sidewalks are exposed to a lot of wear and tear. When the soil supporting it becomes weak or a void is formed, concrete slabs can crack and sink. There are many things that can create a void beneath a concrete slab, such as erosion from rainwater or gutter runoff, or a tree root that has rotted over time. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. Dirt fill underneath the slab that has not been well compacted can also create voids beneath concrete.

• How long does it take to get my concrete leveled?

  It depends on the concrete repair method you choose. Concrete leveling with PolyLevel is the quickest and most efficient route. Most concrete leveling and repair projects take our crews a single day to complete, and PolyLevel cures quickly, allowing your concrete to be used normally the same day. Alternate solutions like mudjacking or concrete replacement often require more time and disruption, as well as longer cure times which could mean parking on the street or avoiding your sidewalk or front steps.

• What types of concrete unevenness could be signs of a larger issue?

  Uneven concrete is extremely common due to wear and tear and changing weather patterns which affect the soils below. In some cases, the damage is cosmetic only; in others it may pose a tripping hazard or trouble pulling into your garage. The most serious concrete leveling problems that we find are those that impact surrounding structures - in most cases, your home. A sinking concrete driveway near your garage can lead to foundation cracks and expensive damage over time.
