This layer is used on the main horizontal area and will be covered with various system components such as insulation, separation layer, drainage/moisture retention layer, growing medium, and soft landscaping. Permaguard-F is also utilized on unexposed detail items. Ensure quick rolling of Permaguard-F into the hot Permatec Anti-Root, with at least 75mm laps sealed using hot Permatec Anti-Root compound.
For exposed upstand details, employ Permaguard-M, a slate surfaced bitumen membrane. Apply it to the second coat of Permatec using controlled torch application, with minimum 75mm laps that are fully sealed.
