Concrete Joint Sealing & Caulking with NexusPro®

Concrete joints deserve an inspection when the existing material has cracked, pulled away from the slab, fallen out or left visible gaps. Open joints should be addressed before wet or freezing weather allows more moisture beneath the concrete. A professional inspection can determine whether the joint needs cleaning, backer rod and new sealant. 

Concrete caulking can’t lift or stabilize a slab that has already settled. It helps protect level or recently lifted concrete by limiting how much water and deicing salt gets into the joints and soil below. If slabs are already uneven, they should be evaluated for concrete leveling before the joints are sealed. 

You can use hardware-store tube caulk, though general-purpose products may shrink, harden, crack or pull away as concrete moves through seasonal temperature changes. NexusPro® is a professional-grade, self-leveling polyurethane sealant applied over properly prepared joints. For homeowners after a cleaner finish and longer-lasting protection, professional concrete caulking is generally the better investment. 

Concrete caulking and surface sealing protect different areas of a slab. NexusPro® fills joints, cracks and expansion gaps with a flexible, waterproof bead that flexes with the concrete. Concrete sealant penetrates the surface of the concrete to help guard against moisture, stains and wear. Used together, they cover both the openings and the surrounding surface. 

In most cases, yes. PolyLevel® restores the slab, while NexusPro® helps protect the repair by sealing joints and cracks afterward. This keeps water and deicing salts from easily reaching the soil below, the same conditions that can contribute to settlement. Leaving the joints open leaves the supporting soil more exposed to future moisture and erosion. 

NexusPro® is engineered as a long-term concrete joint seal. Its flexible, self-leveling polyurethane formula stands up to UV exposure, water, deicing salts and repeated freeze-thaw cycles without turning brittle. It’s professionally installed and backed by an industry-leading transferable warranty, delivering more durable protection than many general-purpose hardware-store caulks. 

Concrete caulking is usually priced by the linear foot of joint or crack sealed. Project cost varies based on total footage, joint width, existing caulk remova, and preparation needs. Since joint sealing is preventative maintenance, it tends to cost far less than repairing settled or damaged slabs later. Schedule a free written estimate for exact project pricing.
