Concrete Garage Repair Solutions

Concrete is heavy, and when the soil supporting it becomes weak, it can crack and sink.

Concrete garage floors are often shielded from extreme weather, but can still be affected by moisture, wear and tear, and the added weight of your vehicle(s), which can lead to cracking, sinking, or more extensive damage, such as cracking, flaking, pitting or crumbling.

Regardless of what’s caused your garage floor to sink, settle or crack, we can fix it. At Thrasher, we offer a comprehensive concrete repair and protection system. After lifting and leveling your garage floor with PolyLevel®, we use NexusPro™ to fill and seal cracks and control joints. Then we apply SealantPro™, which permanently bonds with the concrete and protects it from moisture, chemical elements and seasonal changes. For garage floors with more significant damage, such as flaking, pitting or crumbling concrete, we use ResurfacePro™ to give your garage floor a brand-new look and restore functionality.

Frequently Asked Questions

  • Concrete can crack over time, often early on in its lifespan as it cures and shrinks. Short hairline cracks in your garage floor are usually nothing to worry about, but can be repaired or refinished for a brand-new look. Larger garage floor cracks or heaving can be a signal that the soil below is expanding, often due to moisture.

  • Short hairline cracks in your garage floor are normal and usually don’t require repair. However, larger cracks, heaving, or gaps between the floor and wall can signal a larger foundation problem. If you notice larger cracks or they appear to be growing, it’s a good idea to have a professional foundation repair inspection and fix the problem early before it causes additional damage. 

  • Pitting, cracking and crumbling can be caused by the harsh chemicals for snow removal. Snow build up on the underside of your vehicle then melts on the garage floor resulting in water. The freeze/thaw cycle over time causes the pitting and crumbling.  Sealing your garage floor with a high quality sealant can prevent pitting.  Thrasher uses SealantPro™ which permanently protects your garage floor.

  • At Thrasher, we use NexusPro, a silicone-based crack and joint sealer developed by our sister company Supportworks, for concrete crack repair and control joint sealing. NexusPro offers a long-lasting and durable solution that will keep moisture from seeping beneath your concrete garage floor, where it can cause further problems. When we install NexusPro, we prepare and clean the garage floor cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. 

  • At Thrasher, we use PolyLevel polyurethane foam to lift and level garage floors. PolyLevel is a lightweight, strong high-density polyurethane foam that lifts and supports concrete without adding weight to the soil beneath. It’s waterproof, so it won’t wash out or dry out like traditional mudjacking material. It’s environmentally friendly, too, with no environmentally harmful chemical leaching. Concrete leveling with PolyLevel expanding foam not only raises your garage floor back to level, but also compacts the soil around it, creating a stable environment that will ensure your garage floor remains level into the foreseeable future.

  • We resurface damaged garage floors with our ResurfacePro system, which coats your broken and unsightly concrete surfaces with a durable layer of polymer cement. This process gives your garage floor a brand-new look and restores its function — and it can be ready for use in just a couple days.

  • Yes, we can lift, level and repair epoxied or coated concrete garage floors. Depending on the exact finish and look of your garage floor, our design specialist will recommend the best solution to address the underlying problem while considering aesthetic results as well.
