Craig and his family have lived in this home for over 30 years. He began to notice a crack in the basement walls and kept his eye on it for years. Craig decided it was time to call Thrasher when he noticed a more visible deflection in the wall. He began to worry that the wall would eventually cave in. Hydrostatic pressure outside of the home builds up pressure around the existing foundation walls. This is due to the soil around the home settling and allowing gaps for water to create pressure, causing the walls to bow. 


For this project, PowerBraces were used to permanently stabilize the existing wall. PowerBrace is a product that is made with galvanized steel and fits the exact height of your walls. A unique feature of PowerBrace is that it is secured at the base of the wall, and has an adjustable feature at the top, allowing for the walls to be straightened over time. Craig and his family can now rest easy that they will avoid total wall failure.

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.

Bowed Wall Repair Using Steel Beams

Bowed Wall Repair Using Steel Beams

Bowed Wall Repair Using Steel Beams Bowed Wall Repair Using Steel Beams

Steel beams are installed vertically against the wall and anchored to the floor joists above and to the concrete floor below.

Thrasher Foundation Repair used steel beams to repair this bowing wall.

The front wall of this house was pushed in 5 inches due to improper drainage and grading. As forces of nature, such as moisture and frost, interact with the soil around your home, the soil expands. That expansion results in a constant inward force on your foundation wall until it can no longer support the pressure, causing cracking, bowing and tipping. This caused large cracks throughout the wall and allowed water to enter the basement. With the Power Brace installed(opens in a new window), the wall is stable and will not move inward. During the dry season, the PowerBrace can be tightened from the top bracket. By tightening during the dry season, the soil shrinks, allowing the wall to move back into place over time. This is a unique design created by Supportworks engineers and tested nationwide.  

This is the second house we have worked on for this customer. He was so pleased with the work we did on his home that he hired us again to work on his rental property.

Thrasher Foundation Repair is a trusted company for customers. They create such a positive experience that customers call to complete other projects. Or they call with concerns they are experiencing and eventually become repeat customers. A former customer contacted us for bowed wall repair in Kansas City. Thrasher Foundation Repair installed steel beams, aka "Power Braces," and a waterproofing system in a rental property after Thrasher lifted and leveled their driveway a few years ago.

PowerBrace system permanently stabilizes your home's foundation walls. Zinc-plated steel beams are custom-fit to your basement wall height and secured tight against your basement wall with brackets anchored to your basement floor and floor joists. PowerBrace's unique, patented design allows the system to be tightened over time, potentially reversing wall failure without invasive drilling or digging on the property. They are designed and manufactured right here in the USA by our sister company Supportworks. 

This is the second house we have worked on for this customer. He was so pleased with the concrete work we did on his home that he hired us again to work on his rental property. Now that's awesome! If this customer would sell this rental property, Thrasher's transferable warranty is offered to the new homeowner. Giving both the seller and the buyer peace of mind knowing Thrasher stands behind their work. With over 45 years of experience, engineering, hands on training, and lessons learned, Thrasher is the trusted foundation repair experts in the Midwest. Thrasher Foundation Repair serves homeowners across a four-state region, Kansas, Nebraska, Central and Western Iowa and Western Missouri. If you need a free estimate, don't hesitate to contact our office. Thrasher will send a local expert to your home. Even though we have offices across the Midwest, we thrive on hiring local. So, the specialist and crew who come into your home live near you! 

Thrasher's production crew began the repair cutting the beams to size so, over time, the wall could be pushed back into place. Before the team could install the beams, the interior waterproofing system was installed. The interior drainage system would be installed at the foundation wall base on top of the foundation footing to catch the water right at its entry point. The homeowner chose a sump pump that included three sump pumps. Two sump pumps that run off electricity and a battery backup pump. Now that the waterproofing system is in place, the crew could install the Power Brace brackets to the floor joist then fasten power braces to the floor and bracket. 

Once installed, the Team Lead did a final walk-through with the property owner answering questions and demonstrating how to tighten the Power Braces during the next dry season. If the homeowner cannot use the torque wrench at 80 pounds, a service tech can come out to do annual maintenance. During the yearly maintenance, the service tech will use a laser level and record the improvement benchmarks and tighten power braces. If something isn't right, he will make it right. He will also service the sump pump, cleaning out the pit from any debris, test the pumps, and clear the discharge lines. Having annual maintenance is vital before the heavy Midwest rains come to ensure the pump will work properly.

Full Foundation and Waterproofing Makeover in Kansas City, MO

This homeowner inherited a family home after the passing of a relative.

He decided to call us because we knew everything that the house needed.

We sent out System Design Specialist Elliot Moles to the home for inspection. Elliot found that there was hydrostatic pressure resulting in wall failure, and the basement had standing water. Knowing that he would need to think outside the box for this home, Elliot came up with a comprehensive plan for him and his team to help support the foundation and waterproof this home. Elliot and his team utilized a full perimeter waterproofing system in the basement, including a new TripleSafe Sump Pump System. The team then went on to tackle the wall failure next. They supported the walls by utilizing PowerBraces and GeoLocks, which are systems that work on the interior and exterior sides of the home to reinstate the house's original position and prevent new collapsing calls.

Sump Pit Back Up in Independence, MO

This homeowner noticed that a pipe from a sewer drain was backing up right after he had a new sump pit installed. It wasn't long before the drain backed up and left him with water in his basement. Confused by what was happening with his new sump pit, he called us as we had installed the sump pit.

We sent Service Technician Joe Martinez to inspect the scene and to discover why the drain was backing up. After testing the flow of the drain and confirming the problem, Joe broke open the concrete around the sump and found the end of the pipe from the drain. He determined that the pipes needed more length so that it can drain properly. He extended the pipe from the drain, then he extended the pipe inside of the sump pit.

After the problem was fixed, and the homeowner saw the drain no longer backing up, he was very impressed with our ability to follow up and insure all issues are resolved fully. The repair was quick and easy and the homeowner was very appreciative that we did not leave a job unfinished.
