How We Lift and Seal Your Concrete with PolyLevel and NexusPro

Is your driveway sinking, uneven, or cracking? You’re not alone. Sunken concrete is a common issue that can be caused by soil settlement, erosion, or moisture changes beneath the slab. Fortunately, there’s a powerful, long-lasting solution that restores your concrete without the mess and hassle of replacement: PolyLevel and NexusPro.

Here’s how the process works—from lifting to sealing—for a smooth, safe, and great-looking driveway.

 

Step 1: Site Inspection and Preparation

Before the repair begins, a trained specialist will inspect the driveway to:

• Determine the areas of sinking or instability

• Identify existing cracks or open joints

• Evaluate the cause of the settlement (often loose or weak soil beneath the slab)

The crew then preps the site by marking lift points and protecting surrounding landscaping or structures.

 

Step 2: Injection of PolyLevel Foam

PolyLevel is a high-density polyurethane foam designed to lift and stabilize concrete. The process involves:

1. Drilling Small Holes

Small, penny-sized holes are drilled through the concrete slab at key lift points.

2. Injecting the Foam

The PolyLevel foam is injected through the holes beneath the slab. The expanding foam fills voids, compacts weak soil, and gently lifts the concrete back to its original position.

3. Monitoring the Lift

The crew uses precision instruments to monitor and control the lift. Because PolyLevel expands rapidly, this step is fast and accurate.

4. Patching the Holes

Once the lift is complete, the injection holes are sealed with non-shrink grout that blends into the concrete surface.

 

Step 3: Joint and Crack Sealing with NexusPro

With the slab now level and stable, the next step is to protect it from future damage by sealing joints and cracks using NexusPro.

1. Cutting Between the Cracks/Joints

A saw is used to carefully widen the existing cracks and joints, opening the surface pores of the concrete to allow for better adhesion and deeper penetration of the NexusPro sealant.

2. Cleaning the Cracks and Joints

Any dirt, debris, or old sealant is removed from the joints and cracks to ensure a clean bonding surface.

 

3. Applying NexusPro

NexusPro is a specially formulated, UV-resistant, silicone-based sealant. It’s applied directly into cracks and control joints with a smooth, professional finish.

4. Finishing Touches

Once applied, the sealant is tooled to ensure a tight seal and clean appearance. If the customer wishes, sand is poured on to the NexusPro so that the joints match the color of their driveway. NexusPro cures quickly and remains flexible, allowing it to expand and contract with temperature changes without cracking.
