Professional Home Foundation Repairs

Thrasher Foundation Repair is committed to customer service and is proud to serve our area. We have a professionally trained team of technicians that are ready to help you find the best solution using quality products from the best manufacturers in the business. We want to work with you so that you can have the best results for your home!

Problems with your foundation can seem like a tiresome thing to have to deal with, but we have the products that can help. Foundation disrepair is often caused by broken or weakened soil that cannot support the weight of the structure.

Common warning signs of foundation problems: 

  • Uneven or sloping floors
  • Cracks in the floor
  • Cracks in interior wall
  • Inward bowing walls
  • Sagging floors over a crawl space
  • Hard to open windows and doors
  • Tilting chimneys
  • Street creep
  • Cracks in exterior wall

This issue can be resolved by installing foundation piers and jack posts which will use stable soil farther down beneath the house. As well, by installing helical piers, I-Beam wall braces or wall anchors, you can permanently correct bowing, leaning walls as well as improve the structural integrity of the house. 

Excellent Basement Waterproofing and Crawl Space Repairs

Crawl Space After

A flooded basement or a sump pump problem can seem like a huge problem. However, we have the products to help remedy the problem and make your basement a dry, clean space again. Some of the major symptoms of a waterproofing problem are damp floors or walls, pooling or standing water crystaline deposits on concrete surfaces, musty odors, and condensation. For crawl spaces, many of the warning signs are the same with the addition of wood rot and sagging floors in the house. 

When waterproofing problems occur, whether in a crawl space or a basement, the first step is to install a professional-grade sump pump like the TripleSafe sump pump. By installing vapor barriers, thermal insulation, and dehumidifiers, you can also seal out moisture and bugs while keeping the space dry, clean, and energy-efficient. For problems with sagging floors above a crawl space, jack posts are the sure way to correct failing supports.

Intelligent Concrete Lifting and Concrete Repair in Ames, IA

Troubles with uneven concrete can cause a serious tripping hazard that can lead to other problems. When concrete in your home, sidewalk or patio begins to sink, then you need the PolyLevel® concrete lifting system. The way it works is that the PolyLevel® gets injected underneath the concrete slab which raises it to the appropriate height so that it can be even with the concrete surrounding it. This is not only quicker and easier than traditional methods, but also more permanent and cost-effective. 

We also offer comprehensive concrete repair services that can restore your concrete slab's appearance and stability. Your concrete can become damaged over time when it is repeatedly exposed to moisture, freezing temperatures, and shifting soils. When your concrete driveway or sidewalk is in poor shape, it compromises the look and value of your home or business. That's why we offer solutions to repair and protect your concrete slabs, including:

    • Cracked Concrete Repair
    • Concrete Sealant
    • Sidewalk Repair
    • Concrete Driveway Repair

By repairing cracked, damaged concrete with proven effective methods, we can extend its lifespan and prevent further damage. Schedule a free estimate for our concrete repair services today!
