WP-980 Waterproof Membrane

WP-980 is a thin, flexible, load bearing waterproofing system which consists of an elastomeric latex compound along with a reinforcing fabric that combine to form a seamless waterproof barrier under ceramic tile and stone installations.

WP-980 also acts as a crack isolation membrane for these same types of applications.
