Neighborhood: Widmer Rd., Shawnee, 66216

There's been some settling in the house and I've been told it's not too bad yet given it's from 1978, but there are still signs of the settling and it's best to just check before it becomes too big of an issue to deal with.

Job Stories From Shawnee, KS
Concrete Repair in Shawnee, KS

This homeowner was getting a new hot tub and realized the concrete where they wanted to put it was starting to fall towards the home, making the hot tub unlevel. They wanted this job done quick and done right, so they called Thrasher. System Design Specialist, Josh Krestine, came out to meet with them. Josh found a downspout sitting next to the concrete which was washing away the soil under. Concrete is super heavy and needs something solid to sit under. He came back to the homeowners with these findings, and together they decided on using PolyLevel foam, which will take place of the soil, lifting the concrete back into the place. The Polylevel foam is waterproof, which will create a long lasting solution for the homeowner so they can enjoy their new hot tub. The homeowners were very pleased with the outcome and we know they can enjoy their hot tub with no worries! 

Front Walkway Concrete Repair

These homeowners had just moved into the house two years with plans on making this their forever home. The front walkway started settling during the winter and now there are visible cracks and voids. They were concerned that it would continue to get worse if nothing was done. They did their research online for companies that could help and landed on us. They were impressed with the reviews, reputation, and financing options and gave us a call. System Design Specialist, Brandon Powers, came out to meet them. He surveyed the area and found the concrete was settling by soil erosion. Brandon proposed we use Polylevel to lift, level, and stabilize the concrete and NexusPro to seal joints and cracks throughout. The homeowners liked this solution and we sent out our installation team. There is no doubt these homeowners have no more worries with their driveway! 

Waterproofing in Shawnee, KS

John has just moved into town, and has a traveling job. When he was back in town for a weekend, noticed water was coming in in several areas of his home. He decided to take off part of the drywall to find where the water was coming from, and found there was more water than he imagined all along the wall. He called Thrasher, and System Design Specialist, Tom Studer, came out to meet him. Tom found the water coming through the cold joint, where the footings of the foundation and walls meet. There was high readings of water concentration on the outside of home near the footing, letting water seep into the home. Tom proposed we use our WaterGuard system at the cold joint to capture the water, and CleanSpace, which is our water vapor system, to catch any water from potential cracks in the walls. One the project was complete, John was so happy with the results. He was happy to get quality work done, quickly, so he can refinish his basement without worries of water getting in.
