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!
