Concrete Caulking Solutions

Concrete is strong, but it’s not indestructible. Soil below your concrete driveway, sidewalk, patio, pool deck or garage slab can soften or erode as surface water runs through open cracks and joints. Weak soils and voids cause concrete to shift and sink, resulting in cracked, uneven surfaces. 

Proper concrete caulking and sealing helps to protect 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. NexusPro offers a long-lasting and durable solution that will stand up to harsh weather conditions and keep moisture from seeping beneath your concrete, where it can cause further problems. 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.

Our Approach to Concrete Caulking

When we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the concrete caulking solution we propose and why. We offer several levels of protection and tailor our recommendation to meet your specific needs. 

NexusPro is a great solution for protecting both new and old concrete as part of a comprehensive concrete protection system. First, your concrete is lifted and leveled using PolyLevel® polyurethane foam. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. Finally, the whole surface is protected from the elements with a coat of SealantPro™ concrete sealant, which permanently bonds to your concrete. When you lift, level and protect your home’s concrete, you can rest assured it will keep looking and working great well into the future — plus you’ll sleep better knowing you’ve got a five-year warranty.
