Are MELT Calcium Chloride Crystals safe for sidewalks and concrete surfaces?
Joe's Assistant

MELT Calcium Chloride Crystals is recommended for deicing asphalt and concrete surfaces that have been designed and constructed for winter weather conditions and deicer usage. MELT Calcium Chloride Crystals will not chemically attack asphalt or concrete. Melted water from the deicing process may soak into porous concrete and re-freeze, creating pressure within the concrete structure. Concrete is resistant to scaling damage if it is air-entrained, mixed, placed and cured according to the recommendations of the American Concrete Institute Committee 201.

Please note, MELT Calcium Chloride Crystals are not recommended for deicing concrete that is less than one year old, precast steps, masonry (stone, brick, mortar joints), or existing concrete that has exposed aggregate, is precast, prestressed, chipped, cracked, spalled or weathered.
