The product is a modified bitumen waterproof coating made from rubber-modified bitumen and special additives through a special process. It may be applied with other waterproof membranes to form a composite waterproof layer. When being used as an independent waterproof layer, its surface shall be protected by an insulation layer. Product model and specification (varying from construction methods): Spraying type, painting type, grouting and sealing type
NRC non-solidify rubber bitumen coating may be applied as a waterproof treatment for newly constructed buildings, or to repair damaged waterproof layers. It is applicable to waterproofing of common places, as well as deformation joints and other special positions. Compared with other waterproof materials, it has unique advantages in waterproof treatment for special positions.
