Concrete Spalling — Madrid, Madrid
Spalling is the flaking, chipping, or peeling of a concrete surface that exposes the rough aggregate underneath and worsens quickly once it starts. It is typically caused by freeze-thaw cycles forcing moisture expansion inside the slab, deicing salts accelerating surface breakdown, or poor finishing during the original pour. A concrete mason grinds away the loose material, applies a bonding agent, resurfaces the area with a polymer-modified overlay, and seals the finished surface to prevent future moisture intrusion.
