Cracks in the driveway are an unappealing look to the home and can cause future damage and settle the concrete. Our team was able to help this customer by sealing the joints and cracks with NexusPro joint sealant. NexusPro protects the joints and concrete by not allowing any water or debris underneath the slab to protect the driveway for years to come.

This homeowner noticed that her front steps leading up to her porch were beginning to pull away from her home, which caused damage to the brick façade as well as presented a tripping hazard. She was concerned about the tripping hazard, so she conducted research into solving this problem. After this research, she found us and she was confident we could help her.

We sent System Design Specialist Bobby Bartow to inspect the stairs and come up with a comprehensive solution for her concrete stair problem. Bobby found that the soil under the front porch steps had been eroding overtime and the soil was no longer able to support the weight of the steps. The steps then broke free from the porch and began to pull away from the home as their weight was not supported. Although this situation was difficult, Bobby and his team knew just what to do. They got to work utilizing PolyLevel foam to lift the stairs to their original position, then they utilized NexusPro Cracked Concrete Repair to seal the cracks and joints of the stairs. 

After the project was completed, the homeowner was so happy that Thrasher was able to fix her problem. Check out her newly repaired porch stairs!

This homeowner was experiencing problems with water in her basement, and the noticed a musty smell start to develop. After looking around for who could help her, she gave us a call for a free estimate.

We sent System Design Specialist Jimmy Hungerford to inspect the basement and determine where the water was getting in, as well as where the smell was coming from. Jimmy found that water was coming in the because of hydrostatic pressure against the foundation wall. The pressure forced water into cracks and weak spots in the foundation. The water then traveled through the drywall and onto the floor which also caused mold to grow behind the homeowner's drywall. Jimmy discussed the problem with the homeowner then demonstrated what solutions would fix this, and the homeowner couldn't wait to see what her finished product would look like. Our team used a TripleSafe Sump Pump System as well as WaterGuard Interior Drainage System and CleanSpace Vapor Barrier to give water a proper drainage path and to seal off the moisture in the air. These systems will also help to prevent water from pooling in the basement in the future, as well as prevent mold from growing in the drywall. 

The homeowner was quite pleased with her new waterproofing systems. Check out her new interior basement systems!

Job Stories From Olathe, KS
Water in the basement in Olathe, KS

These homeowner had installed a French Drain nearly 15 years ago. They noticed recently the side of house was getting water inside, and imagined the drain was clogging. They called Thrasher because they knew we would be able to find a permanent solution. System Design Specialist, Tom Studer, came out to meet with them. After the inspection, Tom found water was going in through the cold joint in the basement, along with a couple of cracks in the wall. Tom decided the best solution to this issue would be to install our waterproof system. This includes WaterGuard and Cleanspace along the wall to efficiently capture the water that was coming at the cold joint and the walls. Cleanspace is a plastic, waterproof shield that is attached to the walls. When the water comes in, the Cleanspace is a barrier between the wall and the basement. The water trickles down and into the WaterGuard. WaterGuard is our drainage channeling system. Once the water enters WaterGuard, it flows to the sump pump and out of the home! Tom discussed this with the homeowners and we got started! These homeowners were so happy to know there will not be anymore water issues in their home!
