  • Lightweight - Won't add weight to existing soil
  • Waterproof - Won't wash out

Job Stories From Plymouth County, IA
Sunken Driveway in Remsen, IA

This Remsen, IA homeowner noticed that after a severe rainstorm a large section of the retaining wall was washed out and took the soil underneath half of the driveway with it. This caused the driveway to sink and create a large drop off from the garage to the driveway. With concerns of pulling into the garage, they called Thrasher to see if there was a possible solution.

 System Design Specialist Dustin Brunsting arrived at the Remsen home to perform a thorough inspection of the sunken concrete. The homeowner didn’t think it was going to be fixable, but Dustin was completely confident we had a solution to repair it as opposed to replacing the entire driveway. The team arrived and carefully injected our PolyLevel foam underneath the concrete to permanently lift and level the sunken slab. The PolyLevel foam was the perfect solution and was able to lift the driveway over three inches to make it level with the garage once again.

 The homeowner was delighted to have their driveway completely repaired for a fraction of the cost of replacing it.

Driveway and Garage Concrete Repair in Hinton, IA

A homeowner in Hinton, IA, was having trouble with voids underneath his driveway and garage. The Thrasher crew was able to fill the voids with PolyLevel. Then we closed up the exposed joints with NexusPro Joint Sealant, and protect the concrete from future surface damage with SealeantPro.

Crawlspace Encapsulation in Merrill, IA

The customer wanted to update their crawlspace so they can make their house more efficient. They didn’t have a big water problem but rather wanted to turn their “outside” space into an inside space and not lose energy with a dirt floor. They chose to fix it with us because of the work we do and the price was fair for the project.

The homeowners were experiencing a draft coming into their crawlspace and could feel the upstairs get hotter and colder during the seasons. They wanted to make their home more energy efficient. We proposed that they take out their current insulation and replace it with our SilverGlo to help with energy costs. We also proposed encapsulation as they did have a dirt floor in the crawlspace. It stood out to me as there was a big difference in humidity levels in the crawlspace as compared to the rest of the basement.
