Watco Waterproofing Membrane is a self adhesive waterproofing sheet made of an elastomeric bitumen and a plastic foil on the top surface. It is ideal for use as a waterproofing membrane, air barrier, or as an underlayment for shingle or tiles. The membrane can be easily cut to size on site making it versatile and easy to use. It must be carefully smoothed down to ensure a good bond between the surface and the membrane. The self adhesive side laps are matted together using pressure applied from a rubber roller.

Watco Waterproofing Membrane Primer should be applied to concrete, metallic or wooden substrates before using the membrane. If using Watco Waterproofing Membrane externally, our Weatherproof Topsheet with stone chippings is needed to protect from UV damage.
