Podium Terrace Roof System
|Architect||Warren & Mahoney|
|Specification||2X 10mm of mastic asphalt roofing to podium and 3x10mm to tree pits|
The clients brief was simple they wanted a product that was durable and would last 50 years. The existing podium of the ANZ tower was deemed to be removed and replaced as part of the tower upgrade. There was limited fall less than 1-100 which is termed as a zero fall roof on the existing podium and these falls were not compliant with today’s code. Due to the existing heights of windows and joinery there were nothing Fletchers interiors could do to improve fall.
Due to the monolithic nature, strength, durability and overall performance of mastic asphalt it was selected for this project. As the product is seamless there was less opportunity for ponding on the surface. A specification of 2x10mm of mastic asphalt roofing was selected to cover the following areas tree pits, green area and podium. A decorative finish of stone tiles on pedestal jacks was selected. Due to lack of height tiles were fully adhered to mastic asphalt on certain areas of the project. Flexco adhesives warranted their glue on the mastic asphalt surface.
