Tom witnessed a young girl crash her bike on the sidewalk in front of his house. Worried that others might trip and get hurt, he knew he had to do something. He also knew that he'd have to replace the concrete completely if he waited any longer and knew that would be a higher price tag.

After doing some research, Tom landed on choosing Thrasher because of our reputation and knowledge. He felt comfortable with us, the solution, and our price. We sent System Design Specialist, Brandon Powers, to inspect the concrete and develop a plan.

Brandon noticed areas of concrete settlement and cracking throughout his driveway, front walkway, and sidewalk. He also saw some issues with drainage in the front of the house where the downspouts were located. 

Brandon proposed a plan and walked Tom through it. After that, our install team got on-site and got to work. We used PlyLevel to lift, level, and stabilize all of his concrete. Then we used NexusPro to repair cracks and seal all joints. We also buried two of his downspouts to help fix his drainage problem.

Tom was so happy with the final result and felt better knowing nobody in the neighborhood would get hurt from his unlevel sidewalk.

Ruby was tired of worrying about her crawlspace. She had very high humidity and her home was feeling the effects of the moisture. She was also worried about the high moisture content in her main living space. 

But her biggest concern was mold growing in her crawlspace and creating bigger problems in the future. She decided this was the time to do something about it. She called Thrasher and we sent out System Design Specialist, Jimmy Hungerford, to inspect.

Upon inspection, Jimmy found that Ruby's crawl space had a very high moisture content and it was causing her entire home to have extreme water moisture in the air and the building materials. On top of that, her sump system was failing and needed to be replaced.

To fix and reduce the moisture in the air, we buried her downspouts away from the home, added a new sump system, and encapsulated her crawl space to protect the home from additional damages. We also added a Sedona Air Filtration system. 

Ruby was happy with the results and was excited to use us for other home repair projects in the future!

This deteriorating foundation wall was about to collapse due to soil pressure on the other side. But our dedicated Kansas City crew, along with our EverBrace Wall System, not only rescued the wall but saved the entire home. EverBrace, our go-to alternative for foundation replacement, features corrugated steel panels and beams that stabilize foundation walls. The gaps behind the steel are filled with sturdy rigid foam, transferring the load from the deteriorating walls to the new support panels.

Job Stories From Grandview, MO
Basement Waterproofing in Grandview, MO

An elderly couple in Grandview, MO were growing tired of having water in their basement and the cleanup required a lot of work and time. Any time it would rain, water would come into the basement and ruin items they had on the floor and cause a mess. Ready to discuss basement waterproofing solutions, they decided to call Thrasher.

The crew was able to identify that the lack of a sump pump was causing water to stay in the basement and not be able to drain out. We successfully installed a sump and leveled out some of the concrete that was allowing water to collect and enter the basement.
