Exposed upstand details require Permaguard-M, a slate surfaced bitumen membrane, applied to the second coat of Permatec using controlled torch application. Ensure at least 75mm laps in Permaguard-M are fully sealed.
For additional protection of the waterproofing system, choose between Permaguard-HDPB (Heavy Duty) or Permaguard-PB protection boards. Install them butt-jointed to the second coat of Permatec compound and seal the joints with 75mm reinforced adhesive tape.
Note: Consider using a drainage layer in podium deck design to provide lateral drainage and prevent saturation of the sand and cement bedding.
Properly detail rainwater outlets and penetrations in the roof waterproofing system, adhering to Permatec Standard Drawings and Masterspec 4414AP specification.
A standard Permatec podium deck system includes various components, such as a drainage layer suitable for the loading, sand and cement bedding, or paver supports, and pedestrian paving.
