Enviro 200P Ultra was specified as an internal waterproofing membrane across multiple buildings within the UNSW redevelopment in Sydney, including the Science & Engineering Building, the Biological Science Building and the UNSW Round House. Selected for its ultra-flexible Class III performance and water-based, urethane-modified formulation, Enviro 200P Ultra provided reliable waterproofing under tiled finishes and supported water containment applications where required. The result was a durable, compliant internal membrane solution suited to the demands of a high-use campus environment.
