   Parging (a thin coat of cement plaster) may or may not be present on foundation walls. Below grade, it is typically applied to concrete block walls before a bituminous (asphalt-based) dampproofing coating is applied. The parging is necessary because the surface of the concrete block is too irregular to allow a continuous coating to be achieved with the bituminous material.
