Concrete Caulking & Joint Sealing with NexusPro®

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

What Is Concrete Joint Caulking?

Concrete caulking packs and seals joints, cracks and gaps with a flexible material that moves as the slab expands and contracts. Closing off these gaps helps stop water and deicing salts from reaching and eroding the supporting soil below.

Caulking is preventative maintenance, not simply a cosmetic upgrade. When your concrete is still level, joint sealing may be all that’s necessary. If the slabs have already settled or gone uneven, they should be lifted first and sealed afterward for longer-lasting protection.

Why NexusPro® Lasts Longer Than Hardware-Store Caulk

NexusPro® is a self-leveling polyurethane sealant designed to remain flexible through seasonal expansion and contraction. It also resists UV exposure, water and deicing salts, making it better suited to the conditions concrete faces in Tampa Bay, Orlando, Miami and Largo.

Unlike store-bought caulk, NexusPro® is professionally installed by LRE Foundation Repair-trained crews who clear away failed material, prepare the joint and lay down the correct amount of sealant for a clean, lasting result.

How It Works

Our NexusPro® Concrete Caulking Process

Step 1

Free On-Site Inspection

A Design Specialist inspects your concrete to pinpoint open joints, cracks and gaps that need sealing. You’ll get a free written estimate covering the recommended repairs and project scope.

Step 2

Prep the Joints

Our crew removes any old or failed caulk and thoroughly cleans each joint. A clean surface lets NexusPro® bond securely for long-lasting performance.

Step 3

Add Backer Rod (When Needed)

For wider joints, we install a closed-cell backer rod before applying sealant. This keeps the sealant depth consistent, improves flexibility and builds a stronger, longer-lasting seal.

Step 4

Install NexusPro®

We carefully apply our proprietary, self-leveling polyurethane sealant to fill each joint, crack or gap. The material flows evenly to create a smooth, waterproof barrier that moves with your concrete.

Step 5

Tool, Finish & Cure

We tool the sealant for a clean, finished appearance, remove excess material and allow it to cure. Most joints are ready for normal use within a few hours, depending on site and weather conditions.

Where Concrete Caulking Belongs Around Your Property

Why Seal Concrete Joints Now?

Open joints allow water and deicing salts to reach the soil beneath your concrete. If the slabs are still level, sealing now can help reduce erosion and future settlement. If PolyLevel® lifting is needed, NexusPro® seals the restored joints afterward to help protect the repair.

Common Applications

  • Driveway expansion joints
  • Sidewalk joints and cracks
  • Patio joints
  • Pool deck edge joints
  • Garage floor joints and cracks
  • Front steps and stoop joints

When Toby bought his new home in Beverly Hills, Florida, he noticed water pooling along the side of his driveway and in front of his garage, caused by the slope directing water toward the house. Our team at LRE designed and installed a custom exterior drainage system to fix the problem for good. We added an enhanced channel drain in front of the garage, connected it to an underground drainage pipe, and tied in the home’s downspouts to safely redirect water away from the foundation.

Now, Toby’s property stays dry and protected — and he couldn’t be happier with the results!

Frequently Asked Questions

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

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

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

Concrete caulking cannot 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

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 installed over properly prepared joints. For homeowners after a cleaner finish and longer-lasting protection, professional concrete caulking is generally the better investment. 

Concrete caulking vs. concrete sealing: what’s the difference? 2026-10-05T15:47:09-05:00

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

Do I need concrete caulking after PolyLevel® lifting? 2026-10-05T15:46:38-05:00

In most cases, the answer is yes. PolyLevel® restores the slab, and NexusPro® helps protect that repair by sealing joints and cracks afterward. This keeps water and deicing salts from readily entering 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. 

What is the lifespan of NexusPro® caulking? 2026-10-05T15:46:12-05:00

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 is professionally installed and backed by an industry-leading transferable warranty, providing more durable protection than many general-purpose hardware-store caulks. 

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

Concrete caulking is generally priced per linear foot of joint or crack sealed. Pricing varies with total footage, joint width, existing caulk removal 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 to get exact project pricing.
