Options for waterproofing below-grade ICF walls exist. Admixtures create impermeable concrete, while spray-applied (spray-on) and peel-and-stick (sheet membranes) are also effective. Dimpled sheet membranes, sometimes called air-gap membranes or drainage boards, are a key component, and are part of a complete drainage system.
Above grade ICF walls require flashings around windows, doors, and other openings.
