While concrete is known to be an incredibly durable and long-lasting material (check out those pyramids, still standing strong with one of the first forms of concrete, poorly mixed and poorly cured concrete is an unfortunate daily occurrence. Crumbling buildings, cracked sidewalks, and other such visual eyesores and structural time-bombs all point to an industry whose concrete is not always of the utmost quality.
If you find yourself saddled with old, crumbling concrete, you certainly want to do something about it, both to protect your investment and to make sure there are no potential structural flaws that could cause damage to your home. While the best way to prevent the problem is to make sure the concrete has been properly mixed, poured, and cured, sometimes we do not have this control. The next best step would be to treat your concrete with a high-quality concrete sealer, to protect it from all sorts of weathering.
The typical method of restoring spalled, cracked, and crumbling concrete is through a multi-step process. Depending on the extent of the damage, the depth of the project will vary. First you will need to patch and fill any cracks. Next you will want to use the Siloxa-Tek 8510 to help protect your concrete from future problems, such as cracking and spalling due to constant UV exposure, extreme weathering, or moisture seepage into the material.
