Full Foundation and Waterproofing Makeover in Kansas City, MO

This homeowner inherited a family home after the passing of a relative.

He decided to call us because we knew everything that the house needed.

We sent out System Design Specialist Elliot Moles to the home for inspection. Elliot found that there was hydrostatic pressure resulting in wall failure, and the basement had standing water. Knowing that he would need to think outside the box for this home, Elliot came up with a comprehensive plan for him and his team to help support the foundation and waterproof this home. Elliot and his team utilized a full perimeter waterproofing system in the basement, including a new TripleSafe Sump Pump System. The team then went on to tackle the wall failure next.

Sump Pit Back Up in Independence, MO

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.

Semi Finished Basement Waterproofing Solutions - KCMO

This homeowner was wanting to revamp the basement layout and replace the carpet, but had a nagging leak they thought they had fixed with replacing the driveway. They wanted to be able to remodel the basement with a permanent repair, so they can remodel and know with confidence it will be water tight. They had seen our trucks out and commercials on TV and decided to reach out to set up an appointment. System Design Specialist, Derek Vaksdal, came out to meet with them. After doing the free inspection, Derek found an egress window had been placed in the home at some point in time. The wall had cracked in the corner and was allowing water to come into the basement. The exterior concrete was broken and slanting towards the home. They had the concrete replaced and it was leaking, so he knew that wasn't the issue. He found the root of the problem was the clay bowl effect. This issue refers to the natural consequence of excavating and backfilling when building a foundation. When that soil is removed and backfilled, it leaves an empty space in a bowl like shape. This was a unique situation as the egress window created a weak spot without proper drainage inside, so the water was also stacking up the window itself. Derek proposed we use our WaterGuard and CleanSpace, as well as a TripleSafe sump pump to insure their basement stays dry all the time. Cleanspace is installed on the wall and collects any water coming in through cracks. It is a waterproof, tarp like material, so it prevents mold growth. The water comes down the CleanSpace and into our WaterGuard. This is our drainage channel that is installed on top of the footing of the foundation. The WaterGuard then flows the water into the sump pump, and out of the home at a safe distance. The homeowner loved this idea, and we sent out our installation team and got to work. There is no doubt they are back to remodeling their basement without worries of water getting in. 

Concrete Repair in Grain Valley, MO

After being told his driveway was unable to be repaired this homeowner in Grain Valley, MO had heard about Thrasher from neighbors and wanted to get a second opinion. This customer did not want to have to replace his whole driveway and was devastated about the news he got from the first inspection. He had sinking concrete all over the driveway and cracks leading all the way up to the house making it an unsafe surface to drive or walk on anymore. 

Our crew came out and looked at the concrete and came to the conclusion that we could repair the driveway and save this customer from having to replace the whole surface. We used our PolyLevel foam to fill the massive voids under the concrete and raise the sinking spots back level creating a flat surface again. After the crew got the concrete level again, they then used NexusPro to seal the cracks and joints to stop further cracking and protect the surface from any further damage. 

This customer was beyond happy with the outcome and couldn't thank us enough for helping him save his driveway. 


Foundation Repair in Lee Summit, MO

This homeowner in Lee Summit, MO had an addition to his house with a crawl space. He was wanting to do some remodeling to the room when he noticed a wall leaning and started to realize the door to the room wouldn't shut as easily. When taking a closer look, he noticed some cracks in the drywall and knew he had a problem so decided to call Thrasher. 

Our team came out and did an inspection on the home when we found the crawl space under the room was beginning to settle causing these issues he was noticing. Due to the current drought that was in the area, it was a common problem happening to many homes in his neighborhood. Wanting to give the customer a permanent solution to this problem, our crew used push piers to give the crawl space and foundation more support in the settling areas. When soil conditions are unknown, push piers are the least risky solutions because they are driven all the way to a stable layer of soil. This homeowner can now remodel his addition without the worry of future damages.

There is no doubt they have no more worries of their driveway and have the peace of mind they deserve! 

Concrete Repair in Raytown, MO

A homeowner in Raytown, MO had lived in their home for many years and had no plans on moving anytime soon. Over the years the concrete in the driveway has been cracking and settling in many places. It has gotten to the point where it is difficult to park the car in the garage and is creating bad tripping hazards all over. They decided it was finally time to get it fixed after all these years, so they decided to give Thrasher a call to have us come out for an inspection. 

After the inspection, the team found they had drainage issues and a downspout that was pouring water next to the driveway causing the soil underneath to wash away. The crew used a downspout extension to move the water down further out away from the home to prevent any further washout. Then to repair the concrete our crew decided to use PolyLevel foam to fill the voids under the concrete and raise it back into the original place making the ground level once again. PolyLevel expands under the slab to give the concrete extra support without adding any extra weight to the soil below. 

After the work was completed, our customer can now use their driveway without having to worry about any tripping hazards or difficulty parking their car in the garage. They were grateful for how fast our team was able to work and how great it looked when completed.

James proposed we install PolyLevel to relevel the concrete and stabilize it, and NexusPro to seal all the joints. Both of these products are waterproof, so they help prevent any further washout. Trey loved this solution and we sent out our installation team. There is no doubt they have the peace of mind they need without worrying about any more tripping hazards.
