Repair solutions for cracked, sinking concrete floors
Signs Of Slab Settlement
When a floor slab settles, the damage can manifest itself in many ways. Along with cracks in the concrete, the floors can separate from the walls as they sink downwards. Alternatively, the interior wall may be pulled down with the floor, separating from the ceiling. Walls can also pull away from other walls, and interior wall cracks can form — commonly off the corners of interior doors.

The Best Solution For The Problem
NexusPro® Joint Sealant
This is a high-performance, silicone-based sealant specifically designed for concrete crack repair. It is ultra-durable, resistant to harsh weather and UV rays, and offers a long-lasting seal. NexusPro helps prevent water from penetrating through cracks and undermining the soil beneath. It cures quickly, allowing for immediate use of the surface.

Application or Installation
- NexusPro: The sealant is professionally applied into the prepared cracks, forming a strong, flexible, and durable bond.
- PolyLevel®: The polyurethane foam is injected through the drilled holes. As it expands, it fills any voids beneath the slab and gently lifts the concrete back to a level position. The lifting process is carefully monitored in real-time to ensure precision.
- SmartJack® System: The steel support jacks are installed beneath sagging joists or beams in the crawl space. They are then adjusted to stabilize the floor system and can potentially lift the floor back to a level position. Any necessary wood repair or replacement is completed at this stage.

Are all floor cracks a sign of a serious problem?
Not all floor cracks are serious. Small, hairline cracks are often a normal result of concrete drying and shrinking. However, if cracks are widening, uneven, or extending into your walls, or if your floors feel bouncy or sag, they could indicate more significant issues like foundation settlement, expansive soils, or crawl space structural problems, and should be professionally inspected.
Can floor cracks lead to water problems in my basement or crawl space?
Yes, cracks in concrete floors can act as direct pathways for water to seep into your basement or crawl space, leading to moisture issues, increased humidity, mold growth, and potential damage to stored items or finishes. In crawl spaces, moisture can also lead to wood rot, further impacting floor stability.
Is it better to repair a cracked floor or replace the entire slab?
In most cases, repairing the cracks and addressing the underlying cause is a more cost-effective and less disruptive solution than completely removing and replacing an entire concrete slab. Slab replacement is typically reserved for severe, widespread deterioration. For homes with crawl spaces, repairing sagging floors with the SmartJack system is also generally preferred over extensive structural rebuilding.
How quickly can I use my floor after the repair?
With our solutions, the return to use is very fast. NexusPro sealant cures quickly, allowing for immediate foot traffic. PolyLevel-treated surfaces are usually ready for normal use within 15 minutes to an hour after the injection. For crawl space repairs, the area is accessible shortly after installation, though a full cure for any new concrete footings may take longer.
Will the cracks come back after they are repaired?
Our repair solutions are designed for long-lasting results. When we address the underlying cause of the cracking, such as stabilizing a settling slab with PolyLevel or supporting a sagging floor with the SmartJack system, the chances of the cracks recurring are significantly reduced. NexusPro provides a durable, flexible seal that resists future cracking.
