Lew is a homeowner in Independence, MO that needed concrete repair for the pool deck. Water would come into the home from the pool deck and the problem needed to be fixed before the problem became worse.  System Design Specialist Daryn Britton went out to the home and recommended filling the voids underneath the concrete slabs to prevent water from moving the concrete. The crew lifted and stabilized the affected concrete with PolyLevel and then filled the joints with NexusPro Joint Sealant. Lew was thrilled by the outcome!

This homeowner has recently been thinking about the age and health of his wife, himself, and their friends that often come over. He wants to protect everyone from falling on their sidewalk and step. Plus he wants to maintain the curb appeal of their home. We sent our team over to take a look at it and decipher what the issue is. We found that the soil around the concrete was dried out from warm weather, making the concrete sink. Then once it started to rain, the soil underneath was slowly washed away. To raise the concrete back up, we used our expandable foam that is injected below the concrete. Then we used NexusPro, a long-lasting silicone joint and crack sealant.

Job Stories From Independence, MO
Wall Deflection Repair in Independence, MO

This family was wanting to use their basement for storage, but was battling a constant issue with water getting in and ruining their things. They had heard of Thrasher and our reputation, so they gave us a call. System Design Specialist, Daryn Britton, came out to meet with them. Daryn did his inspection and found there was deflection in the wall which was causing the water issue. Soil movement and water collection from the outside pushed up against the wall causing the wall to bow in and crack. To help combat this issue, Daryn proposed we use CleanSpace to collect the water getting in from the wall and PowerBraces to stabilize the wall. The family loved this solution and we sent out our installation team. There is no doubt they have peace of mind when storing things in their basement now! 

Sump Pit Back Up in Independence, MO

This homeowner noticed that a pipe from a sewer drain was backing up right after he had a new sump pit installed. It wasn't long before the drain backed up and left him with water in his basement. Confused by what was happening with his new sump pit, he called us as we had installed the sump pit.

We sent Service Technician Joe Martinez to inspect the scene and to discover why the drain was backing up. After testing the flow of the drain and confirming the problem, Joe broke open the concrete around the sump and found the end of the pipe from the drain. He determined that the pipes needed more length so that it can drain properly. He extended the pipe from the drain, then he extended the pipe inside of the sump pit.

After the problem was fixed, and the homeowner saw the drain no longer backing up, he was very impressed with our ability to follow up and insure all issues are resolved fully. The repair was quick and easy and the homeowner was very appreciative that we did not leave a job unfinished.
