Concrete Crack Caulking Solution

Cracked concrete is more than just an eyesore that can lower the value of your home. These cracks provide moisture a way to seep beneath your driveway, sidewalk or patio, which can cause the underlying soil to soften or even wash away completely. That in turn can cause the concrete slab to crack further as it sinks into the void left by the washed-away soil. This is why proper concrete crack caulking is so important.

NexusPro finished crack repairRepairing and sealing concrete cracks with caulking not only improves the curb appeal, but also protects your driveway or walkway from soil erosion, prolonging the need for replacement or repairs down the road. At Thrasher Foundation Repair, we use NexusPro™, a silicone-based crack and joint sealer developed by our sister company Supportworks and engineered to stand up to harsh weather conditions. 

When we install NexusPro, we prepare and clean the concrete cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products.

Frequently Asked Questions

  • We use NexusPro silicone-based sealant to fill and seal cracks and control joints after lifting and leveling the concrete steps with PolyLevel. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products, and it’s been proven to last more than twice as long.

  • In short, it depends. While small cracks in your concrete can likely be patched with a sidewalk crack filler from your local big box store, this won’t fix the underlying settlement problem and more cracks can form in your sidewalk. Do-it-yourself repairs might be less expensive, but they are messy, require special tools and equipment, and it can be as long as 30 days before you’re able to apply significant weight to it again (like your car, for example).

  • Concrete caulking repairs are part of maintaining your concrete surfaces and help prolong the life of your concrete driveway, sidewalk or patio. NexusPro is often installed as part of our comprehensive concrete protection system, which comes with a 5-year warranty and has been proven to last over 20 years. 

  • When concrete cracks turn to pitting, crumbling or flaking concrete, caulking may not be enough to repair the surface damage. Instead, we typically recommend our ResurfacePro system, which coats your broken and unsightly concrete surfaces with a durable layer of polymer cement. This process gives your concrete a brand-new look and restores its function.

  • All cracks and joints in your driveway, including concrete expansion joints, should be caulked and sealed to prevent water intrusion which leads to soil erosion. 

  • Yes. We use NexusPro silicone-based sealant to repair and seal concrete cracks, as well as to seal control joints after lifting and leveling the concrete with PolyLevel.

  • There are several factors that influence the cost for repairing concrete cracks with caulking, including the extent of the damage and the method of repair. When we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the solution we propose to repair your concrete cracks and why.
