Concrete Leveling Solutions

At Thrasher Foundation Repair, we use PolyLevel® for concrete leveling because it’s a fast and effective way to lift and stabilize sinking concrete. Polylevel is a lightweight, strong high-density polyurethane foam developed by our sister company Supportworks and only available to an exclusive network of foundation and concrete repair contractors. It lifts and supports concrete slabs without adding weight to the soil beneath, and 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.

Our comprehensive concrete protection system provides additional durability. First, your concrete is lifted and leveled using PolyLevel® foam. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. Finally, the whole surface is protected from the elements with a coat of SealantPro™, which permanently bonds to your concrete. When you lift, level and protect your home’s concrete, you can rest assured it will keep looking and working great well into the future — plus you’ll sleep better knowing you’ve got a five-year warranty.

Our Approach to Concrete Leveling

When we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the concrete leveling solution we propose and why. We offer several levels of protection and transparent pricing to meet your specific needs. 

We use PolyLevel to lift and level concrete. PolyLevel polyurethane foam is pumped beneath cement 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 is waterproof, so it will never wash out, and it won’t degrade over time due to temperature extremes. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Best of all, PolyLevel cures quickly, allowing your concrete to be used normally the same day.

Frequently Asked Questions

  • 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.

  • 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.

  • 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.

  •  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.

  • 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.

  • 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.
