Duram Durabit is water-based bituminous waterproofing coating that forms a durable and flexible waterproofing barrier. With excellent adhesion, Durabit can be built up to a non-sagging coating. Durabit is suitable for permanent immersion in water and will not taint the water, making it ideal for cement dams, water features, box gutters and behind tiles in showers, bathrooms and kitchens. Durabit is an affordable waterproofer for non-exposed areas such as retaining walls and cavity walls and can be used on roof joints and screws when coated with a bituminous aluminium UV protection coat.
