Like all masonry, concrete is subject to deterioration problems such as (alphabetically): blistering, chipping, coving, cracking, crazing, crumbling, delamination, detachment, efflorescence, erosion, exfoliation, flaking, friability, peeling, pitting, rising damp, salt fretting, spalling, subflorescence, sugaring, surface crust, and weathering—most of these caused, as usual, by water.
