For cracks less than one half inch wide, several caulk and sealant options are available. Simply caulk the crack, then use a trowel to spread the caulk evenly. A caulking option will dry quickly, within a couple of hours. For deeper cracks, we recommend using an epoxy sealant.
How to Fix Concrete Slab Cracks?
Concrete slabs are commonly used for driveways, patios, sidewalks, and other outdoor structures. Unfortunately, over time, concrete can develop cracks due to weather, age, and other factors.
However, there are a few ways you can fix these cracks and restore your concrete slab. The first step to fixing concrete slab cracks is to inspect the area and determine the cause of the crack.
If the crack is due to a shifting foundation, you may need to consult a professional to correct the issue. If the crack is due to weathering or age, you can likely fix it yourself.
Once you have identified the cause of the crack, you will need to clean the area. Use a wire brush to remove any debris and dirt from the crack.
Once the area is clean, fill the crack with a concrete patching compound. Make sure the compound is approved for outdoor use, as some products are only suitable for indoor use.
Using a trowel, spread the patching compound over the crack. Make sure the patch is level with the concrete slab and gives it a smooth finish.
Allow the patch to dry for 24 hours, then cover the area with a sealant. This will help protect the patch from moisture and further damage.
