You can buy special caulk at your local hardware store, such as Menards, so you might be tempted to caulk your concrete by yourself. But some caulks from hardware stores can dry out, crack, and bubble when exposed to the sun and other elements or contaminants. At American Waterworks, we used a silicone-based sealant called NexusPro that offers a long-lasting solution that will prevent moisture from seeping underneath the cracks that are caused by soil erosion.
The first step in our NexusPro process is to prepare the cracks and joints, which could include removing all debris, existing sealant, and grinding out the cracks. Second, our NexusPro is applied to the crack and compressed down into the joint or crack, which provides the concaved impression of the NexusPro. Lastly, the joints and cracks are blended with a fine layer of sand that is locally sourced. The purpose of this sand is to give the concrete a polished, orderly appearance.
