Ann and her husband are homeowners in El Dorado, KS, where they plan on living out their future. The appearance of their driveway had bothered them for a long time, and they weren’t sure if it was best to replace it or have it repaired. Before making the decision, they gave Thrasher a call to inspect the cracked and sunken driveway. Our System Design Specialist, Sheldon Sharp, assured Ann that their driveway could be repaired and for a much lower cost than replacing it.

After walking Ann and her husband through the process, they opted to have our crews install our 2-part concrete protection system that consists of our PolyLevel and NexusPro solutions. PolyLevel is positioned first by injecting the concrete lifting foam beneath to fill the voided areas and level the surface. After the concrete is level, our NexusPro sealer is applied to all cracks and control joints to prevent water from infiltrating in the future and causing similar damage.

Ann and her husband couldn’t have been more satisfied with the results of our concrete solutions. Their driveway was now ready to stand the test of time for their forever home in El Dorado, KS.

Ross, at the local VFW Post 1174 in El Dorado, KS knew it was time to address the water in the basement of the building. This was limiting the storage and workspace that they needed to expand their services to local Veterans. Ross liked the reputation we had on the local radio station, KBFR, and knew Thrasher would get the job done right. El Dorado is located near a large lake, where bedrock is shallow allowing for overflow. This, and the soft soil around the footing of the structure, allows for water and pressure to build up in the fill soil. Over time, this pressure causes water to enter the building through the footing of the foundation. 


For this project, WaterGuard was used at the footing of the foundation, this product is designed for water to flow through the open holes and naturally flow towards a Sump Pump. A TripleSafe Sump Pump was installed for this project, meaning there are three "fail-safes," for the pump. It will work for a large amount of water with the triple backup. CleanSpace was then installed for more protection, as deterioration was starting to happen with years of water buildup. 

Spongy Wood Floors in El Dorado, KS

Spongy Wood Floors in El Dorado, KS Spongy Wood Floors in El Dorado, KS

This homeowner recently refinished his floors and wanted to make sure they weren't going to get ruined or "spongy". When we went to the property to perform the inspection, we found the humidity and moisture levels of the wood flooring in the crawlspace was causing the wood to soften and sink, resulting in the spongy feeling they had on the main level on the home. 

The existing concrete support columns were spaced too far apart, which only cause the issue to get worse. On top of that, there was an area under the washer/dryer and kitchen that had zero support with a failing concrete cinderblock, making the entire floor very unstable. 

To fix, we used our CleanSpace vapor barrier system to encapsulate and isolate the earth from the rest of their home, which will help prevent moisture from eating into the wood flooring above. It'll drastically reduce the humidity levels and keep the floor as strong as possible. We also installed our SmartJack system and supplemental beams to solidify the floors and help better support their home.

Egress Window in El Dorado, KS

Renee and Ryan were getting ready to have their third child, so they needed to plan to move their older two downstairs. They want to make sure they have an extra escape route in case of emergencies. They knew of Thrasher and our reputation, so they gave us a call. System Design Specialist, Clint Gerber, came out to meet with them. To ensure safety of their kids in their bedrooms we installed an egress window with our large window to create another exit for the children. They were both excited to have another exit for their children in the basement. 

Concrete Repair in El Dorado, KS

Our customer in El Dorado, KS noticed his neighbor getting their driveway and sidewalk repaired by Thrasher and was impressed by the work so decided to give us a call. He was wanting to give his driveway approach a cleaner and more appealing look. His driveway had cracks and settling spots all over making the concrete look old and broken. 

After coming out to look at his concrete, our crew found that over the years the soil underneath began to sink due to wet conditions. The team was able to use PolyLevel Foam to fill the void under the concrete making the driveway level again, then used our NexusPro to seal all the joints and cracks to prevent water from getting under the concrete causing this issue again. His driveway is now protected from future settlement and gave him the clean look that he was looking for. 

Foundation Repair in

This homeowner was seeing his garage pulling away from the house. He was going to be retiring soon and was putting a lot of work into keeping his home in great condition. He knew he wanted a company that was trustworthy and that could give him a good solution to his problem. He called Thrasher, and System Design Specialist, Travis Hickman, came out to meet with him. Travis saw the reason the garage was pulling away, was because his foundation was settling. The garage and the SW portion of the house were settling causing stair stepping cracks in the basement as well. Travis proposed we use Push Piers to support the foundation. Push piers connect the house to stable, load-bearing soil or bedrock. The homeowner did not want any more settling and was excited for this project. We sent out our installation team and got to work! This homeowner was so happy that Thrasher was able to stabilize and lift his home. There is no doubt he has the peace of mind he was looking for going into retirement.

Brad inspected the foundation and floors and found the floors were sagging and causing soft spots and cracking when walked on. Brad proposed we use our SmartJacks and Supplemental Beams in their crawlspace to attempt to lift, level, and stabilize the floors permanently. The homeowner knew this was the best solution to his problem, so we sent out our installation team! He was so happy with the results. There is no doubt Thrasher gave this homeowner the peace of mind he was looking for. 

Waterproofing at Local VFW in El Dorado, KS.

There had been water for years in the basement of VFW Post 1174 in El Dorado, KS. The gentleman who help maintain this building, and help local veterans, Ross, knew it was time to fix the existing issues. In the basement of this building is a bar area, as well as office space. Due to water in the basement, they have been unable to renovate the space to create more room for operating. Due to the years of water damage, there were also signs of deterioration of the walls and space as a whole. El Dorado has a large lake that is on the cusp of the Flint Hills where bedrock is fairly shallow with respect to the rest of Kansas. So there are many businesses in the area that are suffering from water getting into the basement. 


This is the first VFW in Kansas, and like many VFWs, they are non-profit organizations that are in place to aid veterans with needs and services. At Thrasher, we pride ourselves on living out one of our values of One Community. Because of this, we were able to do this project at cost of the materials for Ross and the team at VFW Post 1174. They will now be able to take the extra funds saved from maintenance to purchasing items needed for local veterans. 


For this project, there was a full perimeter Water Guard was installed. Water Guard is used at the footing of the foundation, to help push water in one direction, while keeping the space dry. The water is then pushed to a Sump Pump, which was also installed on this project. The Sump Pump will take the water, and pump it out and away from the building. CleanSpace was then used to add extra protection from water getting into the basement of the VFW. With these systems in place, Ross and the VFW team will be able to utilize the basement for more space to grow and aid local Veterans.
