Job Stories From Derby, KS
Foundation Settlement in Derby, KS

These homeowners were worried about cracks in their forever home. They wanted to fix the problem now before it got worse and cause more expensive repairs in the future.  They wanted a reliable and trustworthy company with a good warranty to back up the work, so he called Thrasher. System Design Specialist, Trenton Songster, came out to meet with them. Trenton did his inspection and found there were multiple factors causing these cracks and settlement. The main issue was improper water management. The water eroded the soil underneath the foundation footing, causing voids. The weight of the home was pushing down on the foundation causing it to crack and settle. To fix this issue, we installed push piers on most of the perimeter of the home. This allowed us to permanently stabilize the home's foundation and provide lift to the side that had settled. The homeowner love this solution, and there is no doubt they have peace of mind of their forever home. 

Water Intrusion Repair in Derby, KS

Cheri is planning on leaving her home to her grandson. She is also going to remodel the basement and does not want to finish it and have water destroy her work. Cheri and her daughter did their research and found Thrasher to be the right fit for them. They loved their all the reviews and believed in our products. System Design Specialist, Clint Gerber, came out to meet with them. Clint did his inspection and found water was entering the home through the cold joint near the wall and basement slab. Hydrostatic pressure was building up and pushing the water through the cold joint. The downspouts were dumping next to the home and allow water to travel straight down the wall. To resolve this issue, we installed WaterGuard and CleanSpace throughout the entire basement. CleanSpace collects any water coming in We also installed an egress to create another avenue to exit the basement. Cheri was very happy with the project as she doesn't have to worry about the water anymore and are able to remodel the basement. 

Concrete Repair in Derby, KS

This homeowner of 12 years started to notice concrete settling and cracks beginning to form at different spots over the past 3-4 years of living in their home. The concrete had been getting worse and worse over the years and finally decided it was time to get it fixed. They had heard about Thrasher through friends and decided to have us come solve their concrete problems.

Our crew determined after inspection that the soil around the house was eroding and causing the concrete to settle and form cracks. We used PolyFoam to fill the void from the eroding soil to raise the concrete back to the original place and stabilize the ground underneath. To seal the cracks and joints, our crew used NexusPro to repair the concrete and prevent any future damage or cracking. 

Our customer couldn't have been happier with the work our crew did and got exactly what they were expecting out of the project. 

Concrete Repair in Derby, KS

This homeowner in Derby, KS, had concerns about the concrete near their front doorstep becoming a safety hazard. As a homeowner for over 30 years, the customer didn’t want the concrete getting any worse. He put his trust in Thrasher because of our 45 plus years of experience and industry-leading solutions.
Thrasher arrived at the home in Derby, KS, and immediately began installing our GutterShutter and 2-part concrete protection system. The estate was never fit with gutters, and during large capacities of rain, they would overflow, and the water would wash out the soil underneath the concrete causing it to sink. For the damaged concrete, our crews installed our PolyLevel foam to lift and level the sunken slabs. Lastly, NexusPro sealer was applied to all cracks and control joints to prevent any water infiltration in the future. The customer was pleased with their Thrasher experience and the efficiency at which our crews operate.
