Scaling Scaling is the gradual loss of a thin surface layer of concrete through peeling or flaking. The damage usually affects the surface finish before the underlying concrete.
Scaling commonly results from freeze-thaw exposure, improper finishing, or insufficient curing of fresh concrete. Over time, the roughened surface becomes more vulnerable to moisture penetration and additional weather damage. Early maintenance can help slow further deterioration.
Frequently Asked Questions About Scaling
What is concrete scaling?
The gradual loss of a thin surface layer through peeling or flaking, affecting the finish before the underlying concrete.
What causes scaling?
Freeze-thaw exposure, de-icing chemicals, over-finishing that brings excess water to the surface, and inadequate curing.
Is scaling a structural problem?
Not initially. It is a surface condition, but the roughened surface absorbs more water and deteriorates faster over time.
How is it avoided on new concrete?
Proper air entrainment, correct finishing technique, adequate curing, and keeping de-icing salts off concrete during its first winter.
