Melodie H. recently purchased this home in Overland Park, KS and wanted to repair the concrete before it was to get any worse with time. With the summer season approaching quickly, she wanted all the concrete surrounding the pool repaired and fully functional. She gave Thrasher a call and we came out to inspect the problematic areas.

System Design Specialist Lukas Popp arrived at the Overland Park home and presented to Melodie our concrete repair solutions. She opted to have us install our 3-part protection system that consists of leveling, sealing, and protection. PolyLevel is injected first beneath the concrete to lift and level it, permanently. NexusPro sealer was then applied to seal all cracks and control joints to prevent any water from seeping through in the future. Lastly, SealantPro was sprayed to cover the surface and protect it from any stains and deterioration.

Melodie was thrilled with the appearance and effectiveness of our 3-part Concrete Protection System. She was happy to have Thrasher be able to provide multiple concrete solutions to take care of all her concerns in one project. We were able to restore her peace of mind give her the confidence she needs to enjoy her new home.

David B. in Overland Park, KS was struggling with his concrete. He previously had the area mudjacked but found this was not working. He noticed that there were critters digging underneath creating voids and the concrete was becoming unlevel again. Looking for a concrete repair solution, that would be long lasting, he decided to call Thrasher to learn more about our concrete repair solutions.

System Design Specialist Lukas Popp arrived at David’s home to inspect the concrete. Lukas found there to be multiple voids and cracks were forming because of those voids. First, we leveled the concrete with PolyLevel, which a foam that is injected into the concrete. Then we sealed the cracks and joints with NexusPro Joint Sealant to prevent water from creating future voids. Then we put a protective layer over all the concrete

This customer was worried that her home was a tripping hazard due to concrete settlement. The biggest area of concern was the front porch. When we inspected, we found that the two slabs on their front walkway had settled at a couple different joints. This happened due to the soil underneath the slab drying out and shrinking, then eroding away when it would rain. 

To fix, we injected a poly foam to lift the slab and eliminate the tripping hazard. We then sealed the joints with a joint sealer to make sure moisture doesn't find its way under the slab again.

Job Stories From Overland Park, KS
Foundation Support in Overland Park, KS

This homeowner has been experiencing sagging floors and cracks in their dry wall. They want to maintain the property value and not have major issues in the future. He knew of Thrasher and our reputation, so he gave us a call. System Design Specialist, Allie Packard, came out to meet with them. Allie did her inspection and found the foundation was settling from the beams in the basement, which was causing the floor to sag. Allie went back to the homeowner to give him the explanation of what the issue was and why it was happening. He really appreciated the thoroughness of the inspection. Allie then went through the solution that would be best to solve the issue and what was best for the homeowner. He loved this solution, so we installed two supplemental beams and four smart jacks in order to raise the floor back into place. There is no doubt the homeowner has peace of mind for the foundation of his home. 

Concrete Repair in Overland Park, KS

Trevor and Joseph moved in last November. They plan on this being their forever home. Since moving in, they have noticed some settling and cracking throughout the driveway and walkway. Although there was some piers and wall support done previously, they wanted everything inspected. Their primary concern is to make sure that structurally everything is in good shape. They also want to make sure there are no trip hazards and that everything looks good aesthetically. They were referred to Thrasher by a colleague, and between that and online reviews, they knew they didn't need to look any further. System Design Specialist, Brandon Powers, came out to meet with them. Brandon did his inspection and found the poor soil compaction and erosion caused the concrete to settle and crack. Brandon took these findings back to Trevor and Joseph with a solution in hand. To fix their problem areas, we used our 3 Part Concrete Protection System. This includes; Polylevel to lift, level, and stabilize concrete, NexusPro to seal all joints and cracks, and SealantPro to deal the seal the concrete. These products together help stabilize the concrete, prevent any more washout, and prevent pitting and spalling of the top of the concrete. They loved this solution and we sent out our installation team. There is no doubt Trevor and Joseph have the peace of mind they need and deserve in their forever home!

Concrete Repair in Overland Park, KS

This homeowner saw a crack forming in his driveway and some settling happening by his garage. He knew this was a tripping hazard and decided to call Thrasher. He knew of our professionalism and knew we could help him. One of our System Design Specialists, Josh Krestine, met with this homeowner. Josh found a couple of things leading to the cracking and dropping of the concrete. He explained there was poor soil compaction, on top of water coming from the downspouts plus natural rain, causing the soil to become soft and the heavy concrete to sink. Josh proposed we use our PolyLevel foam to lift the concrete. The PolyLevel is waterproof and allows us to life and stabilize concrete for a long period of tine. This will eliminate trip hazards and damage to tires on cars. The homeowner loved this proposal, and loved the work even more when completed. He was surprised how cheap it was to add so much protection to his driveway!
