Concrete Joint Sealing & Caulking with NexusPro®

Close concrete joints, cracks and gaps with NexusPro® to block water, reduce freeze-thaw damage and help protect against future settlement.

What Does Concrete Caulking Do?

Concrete caulking seals joints, cracks and gaps using a flexible material that shifts with the slab as it expands and contracts. Closing these openings helps keep water and deicing salts from reaching and eroding the supporting soil below.

Caulking is preventative maintenance rather than a purely cosmetic fix. When your concrete is still level, joint sealing may be all that’s necessary. If the slabs have already settled or become uneven, they should be lifted first and sealed afterward for longer-lasting protection.

Why NexusPro® Outlasts Hardware-Store Caulk

NexusPro® is a self-leveling polyurethane sealant engineered to stay flexible through seasonal expansion and contraction. It also holds up against UV exposure, water and deicing salts, making it better equipped for what concrete deals with in [Target Location].

Unlike off-the-shelf caulk, NexusPro® is professionally installed by NV Waterproofing and Foundation Repair-trained crews who remove failed material, prepare the joint and apply the correct amount of sealant for a clean, durable result.

  • Sunken Concrete Step Repair in Stephens City, VA

    This Stephens City, VA homeowner was dealing with a sunken concrete front step that had settled over time, creating an uneven entryway and a noticeable tripping hazard near the front door. Sunken concrete steps can make everyday foot traffic unsafe for homeowners, guests, and delivery drivers, while also taking away from the home’s curb appeal. Our concrete repair team lifted and leveled the front step back to its proper position, creating a safer, more stable walkway and entrance. This concrete step repair helped reduce the risk of falls, improved the look of the front entry, and gave the home a cleaner, more welcoming appearance. The homeowner was thrilled with the outcome — a big transformation that improved both safety and curb appeal!

  • Basement Waterproofing in Winchestor, VA

    A homeowner in Winchester, VA, was struggling with a failing sump pump that couldn’t keep up during heavy rainstorms, leaving their basement vulnerable to water intrusion. The lack of a reliable backup system also left them worried about potential flooding during power outages. Frustrated and seeking a dependable solution, they contacted NV Waterproofing and Foundation Repair, a trusted basement waterproofing company in Winchester, VA.

    After assessing the situation, we replaced their old sump pump with a state-of-the-art TripleSafe Sump Pump system. This advanced system includes three levels of protection: a primary pump, a secondary pump for heavy water flow, and a battery backup to ensure the basement stays dry even during power outages. The homeowner now has peace of mind knowing their basement is fully protected, no matter the weather.

  • Pool Deck Leveling in Manassas, VA

    A homeowner in Manassas, VA, quickly realized their dream backyard pool was at risk when the surrounding concrete pool deck began to show serious problems. Uneven and sunken slabs created tripping hazards and unsightly cracks, making both safety and aesthetics a challenge for anyone using the space. Additionally, water from rain and pool use was pooling in low spots, causing slippery surfaces and further soil erosion beneath the deck. These issues not only threatened the safety of family and guests but also compromised the value and enjoyment of the home.

    Seeking an effective solution, the homeowner reached out to our team for a professional assessment. We identified the main cause of settlement: soil erosion under the slabs—a common issue in Manassas due to its clay-rich ground and fluctuating moisture. To address both the immediate hazards and prevent future damage, we recommended our two-part approach: the cutting-edge PolyLevel® concrete leveling system and NexusPro® Joint Sealant.

    The repair process began with drilling small holes into the affected concrete slabs, allowing us to inject high-strength PolyLevel® polyurethane foam beneath the surface. As the foam expanded, it filled voids, stabilized the soil, and gently lifted the slabs back to their original positions. The process was quick, clean, and minimized disruption, giving the pool deck a level, safe surface once again. PolyLevel® foam is waterproof and lightweight, reducing the risk of future settling and ensuring long-term durability, even in a wet poolside environment.

    To provide further protection, we sealed all cracks and joints with NexusPro® Joint Sealant. This flexible, weather-resistant sealant prevents water from seeping beneath the slabs, protecting the soil and concrete from additional erosion. The result was a clean, finished appearance that not only improved the look of the deck but also safeguarded it for years to come.

    Thanks to modern concrete leveling technology, the homeowner’s pool deck was transformed from a liability into a safe and attractive outdoor gathering space. The project was completed in a single day, with minimal mess and immediate results, giving the homeowner peace of mind and renewed pride in their backyard. If you’re facing similar issues with your pool deck in Manassas, VA, the PolyLevel® system and NexusPro® Joint Sealant offer a fast, effective, and lasting

Frequently Asked Questions

When should concrete joints be recaulked? 2026-10-05T15:49:03-05:00

Concrete joints should be inspected once 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. 

Can concrete caulking stop a slab from sinking? 2026-10-05T15:48:03-05:00

Concrete caulking can’t lift or stabilize a slab that has already settled. It helps protect level or recently lifted concrete by reducing the amount of water and deicing salt entering the joints and soil below. When slabs are already uneven, they should be inspected for concrete leveling before joint sealing. 

Can I caulk concrete myself using tube caulk? 2026-10-05T15:47:33-05:00

Hardware-store tube caulk is an option, but 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 installed over properly prepared joints. For homeowners after a cleaner finish and longer-lasting protection, professional concrete caulking is generally the better investment. 

How is concrete caulking different from concrete sealing? 2026-10-05T15:47:09-05:00

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

Should I have concrete caulking done after PolyLevel® lifting? 2026-10-05T15:46:38-05:00

Usually, yes. PolyLevel® restores the slab, and NexusPro® helps protect that 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 keeps the supporting soil more exposed to future moisture and erosion. 

How long does NexusPro® caulking last? 2026-10-05T15:46:12-05:00

NexusPro® is built 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 is professionally installed and covered by an industry-leading transferable warranty, offering more durable protection than many general-purpose hardware-store caulks. 

How much does concrete caulking cost? 2026-10-05T15:45:39-05:00

Concrete caulking is typically 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. Because joint sealing is preventative maintenance, it is often far less costly than addressing settled or damaged slabs later. Schedule a free written estimate for exact project pricing.
