Concrete driveway surface scaling and flaking — Haarlem, Noord-Holland

Scaling is the progressive peeling and flaking of a concrete driveway's top surface, exposing rough aggregate underneath and making the driveway look patchy and deteriorated. It is typically caused by repeated freeze-thaw cycles that trap moisture in the pore structure, excessive use of deicing salts, inadequate air entrainment during the original pour, or premature finishing that sealed bleed water under the surface. A concrete mason removes all loose and delaminated material, applies a bonding slurry, installs a polymer-modified resurfacing overlay, and seals the finished surface to protect against future moisture and salt penetration.
