Before & After Photos

Owners of public buildings must be very cautious about having tripping hazards on sidewalks.

All concrete slabs settle – it’s a matter of when, not if, it will happen.

The Raytown School District has used Thrasher Foundation Repair on many occasions to maintain the safety of the sidewalks and flatwork around their schools and office buildings.

Owners of most public buildings are required to repair any public sidewalk or entryway that has more than 3/4″ differential movement from one piece of flatwork to another.

Thrasher was hired to eliminate any potential tripping hazards along the sidewalks and entryways at one of the district's office buildings. We were able to return all the concrete flatwork to the original condition without interrupting their working schedule or the facility's function.

Although we do not use or provide mudjacking services today, we provide a polyurethane injection system, PolyLevel, to offer an economical, quick and effective solution for lifting situations like these and residential sidewalks, patios and driveways.  

Sunken or heaved concrete slabs can present tripping hazards that you may be liable for as a homeowner. Concrete repair is essential to protect your driveway, sidewalk or patio for the future. 

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 that 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 them, 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:

1. Your concrete is lifted and leveled using PolyLevel® foam.
2. Your cracked concrete and control joints are filled and sealed using NexusPro joint sealant.
3. 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.

When we visit your home for the first time, you can expect a thorough inspection and a detailed 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 ground 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 ecologically harmful chemical leaching. Best of all, PolyLevel cures quickly, allowing your concrete to be used usually the same day.

1. Reduces Moisture and humidity

2. Helps to keep cool drafts out

3. Extremely durable and can fit many wall and floor dimensions

4. Compatible with other crawl space materials

5. 25-year warranty

This driveway was able to get a new fresh and clean look after our crew was done! Using PolyLevel foam to fill any voids and bring the concrete back level, and NexusPro to seal any joints and protect the concrete from future damages. The customer couldn't believe the results!

This porch was left with a serious risk of settling or complete failure after various rain showers and other weather conditions left a void under the concrete. Our PolyLevel foam was the perfect solution! This foam gives the concrete the support it needs without adding any extra weight to the ground below and is built to last in the conditions.
