 An effective green roof drainage system to complement a green roof system is absolutely essential to ensure that no related damage is caused to your roof or property and the system can become fully effective.
Modern green roofs are made of a system of manufactured layers deliberately placed over roofs to support growing medium and vegetation and are highly effective. Green roofs and living walls are a great way of providing an attractive, useful, environmentally friendly open space on an otherwise ‘lost’ flat roof or podium deck.
Green roofs must have a quality green roof drainage system to carry away excess water and Wallbarn’s Protecto-Drain system is the most effective green roof drainage system on the market.
Unimpeded drainage is assured in green roof systems because the green roof drainage system is applied over the entire roof area. The green roof drainage system is used to create an extremely stable and pressure resistant sub-base.
Although some people believe the implementation of a green roof drainage system is not necessary on any sloped roofs due to nature's gravitational drainage capacity, to ensure the best possible results are attained one should always be implemented.
When installed with a well performing green roof drainage system, a green roof will provide the following benefits:
- Improving the local environment by providing wildlife habitats
- Improving sound and thermal insulation
- Reducing the amount and speed of rainwater run-off by around 50% and forming part of a SUDS design
- Reducing the “heat island” effect in built up areas and helping to improve air quality and environment
- Protecting the structure and waterproofing systems from UV, impact and abrasion, plant and bird infestation on the membrane
- Ballasting inverted waterproofing systems
- Optimising the structural footprint by providing extra space and an attractive natural area in often high density developments
- Making the planning process a lot easier
- Increasing the value of the development
