Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, the design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts, and cracks.
