With a number of material options available for roof and balcony membrane drainage products — each suitable for different project requirements — it's important that architects carefully consider membrane type, flow rate, spatial requirements and environmental factors to choose the best option for the application. 

Linear channel drainage systems provide an excellent solution for efficiently removing surface water from large areas and openings such as laneways, paved areas and garage entrances. When selecting a system, consideration should be taken to the application and load class requirements.

When detailing a membraned area, the selection of the outlet is of prime importance. 

Selecting the correct floor waste system can save time and materials by simplifying the passive fire protection of each penetration in your projects.

Meeting the requirements of chapter 7.3.2.1 of E2/AS1 in regard to level threshold is getting easier with the rise of perimeter drains as an off the shelf answer to this detail. The new solution we look for is how you deal with steps in the building line, and how, as an architect, you can detail and select a system that will meet the aesthetic and accessibility requirements of this situation.
