NOVAR-WS is a waterproofing membrane Plastomeric Anti-root, designed to absolutely guarantee the resistance to the roots. This property has been achieved through the use of armor composite structure constituted by a synthetic organic component impenetrable by the roots, supported and rendered stable within the mass by a non-woven polyester stabilized with glass fibers. The waterproofing compound is composed of distilled bitumen modified with metallocene polyolefin polymers of origin. The membrane has the upper surface coated sand amorphous anti-adhesive and the bottom surface coated with hot melt polyolefin film.
