Cracked and uneven concrete sidewalk

What causes concrete to crack?

Poorly compacted soil: When your home was built, soil movement around the building site results in poor compaction. Even when the replaced soil is compacted well, it's never as stable as the original soil. Over time, this can cause voids to form and slabs to settle.

Dry soil: Another cause of soil failure is drought. During dry conditions or even just during periods of warm weather and low precipitation, the soil under your concrete will dry out and shrink, creating voids. The concrete above eventually cracks and sinks into these empty spaces, especially if any weight is placed on it.

Flooding: When the rains return, the water has an even easier pathway under the slab due to cracks and crevices left over from the dry period. And this wet, soft soil is too weak to support the concrete above it. In the worst case, the soil erodes and washes away completely, leaving behind large voids that cannot support the weight of the concrete above.

More FAQs

  • How much does cracked concrete repair cost?

    Our NexusPro solution is cost-effective over the long term because it offers a long-lasting solution, unlike the urethane-based products available at big-box DIY stores that must be replaced regularly.

  • What is NexusPro?

    NexusPro is a silicone-based sealant for joints and cracks specially formulated to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble, or dry out. That means a single application can seal the joints and cracks in your concrete driveway, patio, pool deck, or sidewalk for years to come, protecting it from damage caused by soil erosion and washout.

  • How long does NexusPro concrete sealant last?

    Because NexusPro is silicone-based, not urethane-based, it won't degrade over time, even when exposed to UV radiation and extreme temperatures. This ensures that it remains flexible and waterproof for years.

  • Can NexusPro work with concrete that has been lifted?

    Yes. We recommend that our customers seal the cracks and joints of their newly lifted concrete with our NexusPro solution, as it will help protect their concrete for many years.

  • Can I repair cracked concrete myself?

    You can, but it might not be a long-lasting solution. While you could seal cracks with urethane caulk found at your local big-box hardware store, that solution is prone to cracking, bubbling, and drying out over time. You'll need to be prepared to monitor and re-seal your cracks regularly, as the conditions that led to your cracked concrete will likely happen again. Our NexusPro solution is highly effective and lasts 5x longer than DIY methods, so contact us and see how we can help!
