Installed two layer membrane to planter boxes Tremproof 3000/Antiroot was used. Tremproof 90 was used on all stairs. Two layer Tremproof 3000 to podiums which had paving installed over the top. Project size was approximately 5345m2.
There were many challenges on this project, none more so than the flashing details both inside and outside the planters.
Internal flashing over the torch applied membrane was Tremproof 200EC, Tremproof 90 and Tremproof 120.
External flashing over the torch applied membrane was Tremproof 200EC, Vulkem 350/351.
Due to the shape of the planters and the Architects requirements we were unable to use conventional flashing on the project.
Podiums - Tremproof 3000 2 layers = 3,468m2
Planters - Tremproof 3000/Antiroot = 1,479m2
Stairs - Tremproof 200EC/Tremproof 90 = 396m2
