Back Patio Repair in Kansas City, KS

This homeowners patio had dropped over the years and started to crack. He uses the back patio to grill and relax, but couldn't use this space will all of the issues it was having. He called up Thrasher because he knew of our quality work. He wanted to be able to relax and use this patio without worries, and knew Thrasher would be able to provide a great solution for him. System Design Specialist, Daryn Britton, came out to meet with him. Daryn noticed there was washout under the slab and soil failure, causing the slab to drop and crack. He proposed we use our Polylevel to lift and level the slab, and the NexusPro to seal the joints and cracks. This homeowner was so impressed with the outcome of the work that he has called us back for his driveway repair. There is no doubt that he is relaxing and grilling with ease now.
