Concrete repair, foundation repair, and basement waterproofing experts in Lenexa, KS.

Lenexa is a beautiful place to live, a picturesque suburban city less than 20 miles outside of downtown Kansas City. Thrasher Foundation Repair has been proud to offer our expert services to Lenexans young and old since 1975, providing the area’s best in basement waterproofing, concrete repair, crawl space encapsulation, and foundation repair.

Like a good deal of cities and towns west of the Mississippi, Lenexa traces its roots back to the American frontier of the mid-1800s. The urban center of Kansas City hugs the banks of the Kansas and Missouri rivers, at a confluence presently located just south of the Charles B. Wheeler Downtown Airport. Lenexa itself was officially platted in 1869, some 12 years after a certain legendary gunslinger, Wild Bill Hickok, staked a claim to 160 acres near what is now the corner of 83rd and Clare Road. For nearly 80 years, Lenexa remained a well-kept Kansas secret, reporting a mere 803 residents in the 1950 census. It appears that someone spilled the beans in the years that followed, as Lenexa’s population grew more than 42-fold from 1950 to 1990.

It’s not hard to see why, either. Lenexa offers an ideal blend of suburban neighborhoods, city access, parks, trails, and events. Our city hosts the Kansas State Championship for barbeque, the Great Lenexa BBQ Battle. If chili’s more your taste, Lenexa’s got you covered there too, with the Lenexa Chili Challenge. And if you’ve got sagging floors, a tilting chimney, water in your basement, or a broken-up driveway, then Lenexa’s got the solution for that as well - its name is Thrasher Foundation Repair.

At Thrasher Foundation Repair, we know Lenexans because we are Lenexans. Our highly-trained teams of professionals will customize a solution to match your exact needs, installing top-of-the-line products to deliver long-lasting results in concrete repair & leveling, basement waterproofing, crawl space encapsulation, and foundation repair.

Your local concrete repair & leveling experts in Lenexa

Wherever you look in suburbia these days, you’re likely to see some concrete. It’s everywhere, from the sidewalks to the roads, to the tops of skyscrapers and in your driveway. While strong by many metrics, concrete is always prone to degradation over time as the elements take their toll. When concrete needs repairing, it’s time to call in Thrasher Foundation Repair.

Concrete Driveway Repair

One of the most prominent degrading factors of concrete is the freeze and thaw cycle. When temperatures drop below freezing, tiny quantities of water hidden within a concrete construction will freeze, causing their volume to swell. When these tiny ice particles thaw out in warmer weather, they leave a void behind them. This process repeats over decades, consistently pressuring a concrete construction until it needs repairs. In Lenexa, winters can get cold. Average daily lows measure below freezing from December through February. With this sort of pressure, it’s common to see cracked driveways, chipping sidewalks, and flaking, pitted concrete structures around town. If you’re dealing with any of these issues, it’s time to call in the experts.

Lasting basement waterproofing services in Lenexa

Nobody wants a wet basement - plain and simple. Water infiltration is a pesky nuisance that many homeowners have to contend with, and a fix to the problem can occasionally feel out of reach. Flooding in Lenexa is always a possibility, following any of the heavy rain events that we’ve grown accustomed to. Our soil, primarily composed of a silty-clay loam, has only moderate drainage capacities and can accumulate water during downpour events. This excess moisture in the areas surrounding your foundation and basement walls can cause hydrostatic pressure, damaging the integrity of the concrete construction over time.

Thrasher Foundation Repair has been waterproofing basements for more than four decades and can ensure a water-free basement for any of our clients. We install drainage systems, fix cracks resulting from persistent water infiltration and pressures, build sump pump systems, and guarantee that water damage in your basement will be a thing of the past.

We offer no-cost, no-obligation basement waterproofing inspection and service estimates across Kansas. Contact us today to schedule yours!

We offer the following basement waterproofing products and solutions:

  • Interior drainage systems
  • Dehumidifiers
  • Window wells
  • Sump pumps
  • And more!

Expert crawl space repair & encapsulation services in Kansas

Crawl spaces, much like basements, can be a vector for damage to your home. Unlike a basement, no homeowner is likely to spend any significant time inside of their crawl space for all the reasons you’d expect - dirt, pests, foul odors and such aren’t exactly inviting to visitors. But it doesn’t have to be this way.

Crawl Space Repair & Encapsulation

Thrasher Foundation Repair has perfected the art of crawl space repair and encapsulation. While we know that a crawl space isn’t a space for entertaining guests, it is a vitally important area of your home when it comes to the overall health of the structure. Ridding your crawl space of dampness, dirt, unwanted pests, and other undesirables can improve your air quality while protecting the home-supporting structural components housed inside it. If those components have already succumbed to damages to any degree, have no fear - Thrasher Foundation Repair can repair and support problem areas in your crawl space, providing peace of mind and long-lasting strength for your home.

We offer no-cost, no-obligation crawl space encapsulation and repair estimates throughout Kansas. Call today to see how we can help!

Nancy K., a homeowner in Lenexa, KS, was finding water in her basement under the garage and wanted to find the source before waterproofing the interior of her home.

Our team came out and determined that the water was coming in due to the sinking of her driveway which created a void that water was able to enter her home.  We lifted the driveway using Polylevel and sealed the cracks with NexusPro to keep the water out.

Lenexa, Kansas homeowner, had a considerable concern with his driveway. It was a 6-inch large drop in front of his garage. Shocked about his discovery, he researched local concrete mud jacking companies. Among the mix of local Kansas City Metro experts was Thrasher Foundation Repair. 

Thrasher, a skilled expert with lifting and leveling concrete, came to the rescue. Once the free inspection date was set, the homeowner received an information packet which included About Us, The Thrasher Difference, Same Day Savings and a concrete repair science book. Although mud jacking or slab jacking was researched, it was not the method used for this homeowner. Let me explain why.

Thrasher used a total of 6.5 cubic yards of material to lift 3 sections of the driveway to match the garage, and 3 sections of the sidewalk to match the driveway.

Traditional mudjacking uses local soil or sand blend, mixed with water and cement, which is heavy and messy when installed through a hole the size of a soda can. Since this mixture is heavy, it can settle the soil after it’s been installed, and you are right back at the beginning. This mixture can also wash out over time, causing the slab to settle back down unlevel. Which means more time spent with a contractor and more money.

During the free inspection with System Design Specialist, homeowners can expect a thorough examination and a detailed explanation of the concrete leveling solution. A common reason for sinking concrete in the soil. Poorly compacted, dry soil is the cause of this large drop in the front of the driveway. During the 60-minute free inspection, System Design Specialist educates the homeowner about the PolyLevel method and warranties and transparent pricing to meet the homeowner’s specific needs. 

Technology and methods for lifting and leveling have come a long way in the last five years. 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. If it would sink back down, Thrasher makes it right. 

Thrasher offers several levels of protection, filling all cracked concrete and control joints with NexusPro joint sealant. Then, the whole surface is protected from the elements with a coat of SealantPro. ™, which permanently bonds to your concrete. 

Our Lenexa, KS homeowner hired Thrasher to strategically injected PolyLevel under the slab and raised it to level with the garage floor. First, the Team leader does a walk-through of the work scope, setting an expectation for the lift with the homeowner and answering all questions or concerns. 

Once work is started, the crew will drill penny size holes strategically in the sunken slab to prep for a level lift. Polylevel injects new, structurally engineered material into any hidden voids to stop and reverse settlement. This is a skilled craft. Each team member goes through classroom training, learning about the mixture and process, then hands-on training with a seasoned Team Lead or Manager. 

Once the work is complete, the driveway and garage can be driven on within 24 hours. The team leader does a final walk through with the homeowner before collecting the final payment. 

Lenexa homeowner was beyond please with the work Thrasher did. The precise execution of the lift and level was perfect! The cleanup of the crew was as if no work had been done in the first place. This Lenexa homeowner is please they went with PolyLevel vs. traditional mudjacking or slab jacking. 

If you have concrete slabs that are significantly cracked, have voids beneath the slabs, or are sloping towards your home or building, it’s time to consult a PolyLevel Expert. PolyLevel is a much more cost-effective alternative to concrete replacement.

This homeowner was using his covered porch space as an exercise room, however he recently noticed that the floor was a bit unstable. He was concerned that he wouldn't be able to exercise in his room if he didn't try to it, so he decided to give us a call. 

We had System Design Specialist Daryn Britton look at the structure of the porch and determine what was causing the floor to feel unstable. Daryn found that the floor was unstable because there was not a strong enough support system underneath the porch. In order to fix this, Daryn suggested that the homeowner had SmartJacks and a new support beam installed. The homeowner liked this solution, so we had an installation team use these products to lift and stabilize the homeowner's porch. The homeowner was happy with the outcome, and he is excited to use the space without worry now. Check out the new support structure under the porch!

A homeowner in Lenexa, KS, wanted to fix their concrete before it got worse. There had been a significant amount of settlement around their driveway and front walkway. The crew used a combination of PolyLevel and NexusPro Joint Sealant to level and close the exposed joints. 

Driveway Repair in Shawnee, KS

This Shawnee, KS home had concrete slabs on the driveway that had sunk severely over the years. To avoid a full replacement and reduce cost, she decided it was finally time to have it repaired. She chose Thrasher because we were able to provide her with an affordable solution that would save the concrete and stay protected under a warranty long into the future.

To begin the concrete repair, System Design Specialist Craig Mueller arrived at the home in Shawnee, KS to inspect the driveway. It was determined the slabs closest to the street had open control joints that were allowing water to flow underneath the concrete and washing out the soil. The homeowner opted to have our team install our 2-part concrete protection system that consists of PolyLevel foam and NexusPro sealer. PolyLevel is installed first by injecting it underneath the concrete to lift and level the slabs permanently. NexusPro sealer is then applied to all cracks and control joints to prevent any water infiltration in the future.
Once the job was completed, the homeowner’s peace of mind was restored knowing her concrete issues were behind her.
