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.

700X Rooftop with 950TC
Case Study – Exposed Rooftop Waterproofing System
A commercial rooftop requiring long-term weather protection and maintenance access was specified with a fully exposed liquid-applied system. The project involved complex detailing around plant equipment, service penetrations, and parapet upturns, combined with ongoing UV exposure and periodic foot traffic.
Enviro 700X was selected as the primary waterproofing membrane due to its seamless application and strong adhesion to the prepared concrete substrate. Its flexibility and crack-bridging properties ensured reliable performance across movement joints and transitions.
To enhance durability and protect against long-term UV degradation, Enviro 950TC was applied as the protective topcoat. This provided additional surface toughness, improved abrasion resistance, and long-term colour stability.
The completed system delivered a fully bonded, UV-stable waterproofing solution capable of withstanding environmental exposure and routine maintenance traffic, ensuring long-term protection of the occupied spaces below.
