Job Stories From Castle Rock, CO
Driveway Repair in Castle Rock, CO

This homeowner had back surgery recently and wanted all of the uneven areas of his concrete leveled to avoid trip hazards. He had a couple other bids before, but wanted Thrashers opinion as well. System Design Specialist, Jeff Schlimm, came out to meet with him. Jeff did his inspection and how the extensive damage to one area of his driveway. His walkway to his front door had settled due to washout over time. Jeff took these findings and went back to the homeowner with a solution. The homeowner was impressed with the inspection and how we showed him the problem and what caused it versus just giving him a number. We used PolyLevel to lift and stabilize the slab, and NexusPro to seal the joints and cracks that were letting water through and causing the tripping hazards. The homeowner was trilled with how the project went and we know he has the peace of mind he needs for his driveway. 

Concrete Repair in Castle Rock, CO

This homeowner was having their concrete in front of their home slant toward the home. This was causing water to slide and build up towards the foundation wall. They knew they needed to get this taken care of, and needed to get someone out. They knew of Thrasher reputation and professionalism, so they gave us a call. System Design Specialist, Mike Williams, came out to meet with them. Mike noticed the front patio was settling towards the house due to poor soil used as fill under the slab. Mike talked with the homeowners, and decided to use our Concrete Protection System. This would consist of PolyLevel to lift and level the concrete back to place, and NexusPro to seal the cracks and joints. The homeowners were extremely happy with the outcome. There is no doubt they are not worrying about any more water getting into the basement!
