Spalling or scaling is a term used to describe the process of flaking or crumbling of concrete due to weathering, corrosion, or other environmental factors.
Spalled concrete can be an eyesore and can also be dangerous in some cases. Luckily, it can be fixed and steps taken to help prevent it from occurring in the future.
Spalling concrete happens more often in cold states like Rhode Island and Massachusetts due to the freeze-thaw cycles and use of de-icing salt.
Spalled concrete can be caused by any of these:
The first step is to clean the concrete surface thoroughly using a pressure washer to remove any dirt or other contaminants. We take special care not to damage your concrete during the power washing.
After the concrete has been cleaned, it is inspected for any cracks. If there are any, we inject a special epoxy or a polyurethane compound to repair them. Read more about concrete crack repair here.
If the spalling is not too severe, it may not need resurfaced with an overlay coat of concrete. It may be enough just to seal it to protect it from future scaling.
If the spalling is excessive, we may resurface it to a brand-new condition with a thin coat of a special concrete mixture.
