Tuff-N-Dri basement waterproofing system consists of a seamless membrane that seals out leaks and seepage from basement walls and an insulating board on the outside that reduces condensation on the inside. Abovegrade, spray-apply the membrane to the exposed foundation to form an uninterrupted protective barrier to water penetration for the whole wall.
