Daku Roof Garden
What is Daku?
Daku Roof Garden System is a unique way of putting back the greenery into the surrounding by converting the roof top of multi storey carparks into roof gardens. It is the greening system for creating both ‘intensive’ and ‘extensive’ roof gardens.
Roof gardens provide many environmental benefits, including reduction of urban heat by lowering roof surface temperature, improve air quality and energy savings through reduced air conditioning requirements. They have also been used as part of an effective storm water management strategy in low-lying and flood prone areas.
Daku roof garden system comprises of special lightweight mix of planting substrate and a unique water storage and drainage element thus resulting minimal maintenance works for roof gardens.
Composition
Daku FSD 20 water storage and drainage element – Made from pressure moulded polystyrene to form large reservoirs that collect rainwater to support plant growth. It can store 16 litres of water per square metre.
Daku Stabil-filter – Separates the Daku substrate from the water storage chambers. Daku Stabil-filter is made from a special mix of polyester and polypropylene. Its excellent capilary action allows Daku Stabil-filter to draw water from areas with high water to areas with low water. This ensures sufficient and even water distribution throughout the roof.
Daku substrate – Daku substrate consists of a unique mix of granulated lava, pumice and fertilizers. The lava and pumice are porous and lightweight and weighs as much as three times less than the conventional soil. The substrate can store up to 39% of water by volume.
Areas of Usage
· Rooftops
· Multi-storey carparks
· Converting existing rooftops into roof gardens
Special Features
· Unique Substrate
Daku substrate consists of a unique mix of granulated lava, pumice and fertilizers. The lava and pumice are porous and lightweight, does not contain sand or silt and hence will not be compacted over time. The substrate can store up to 39% of water by volume.
· Unique Filter
Daku Stabil-filter is made from a special mix of polyester and propylene. Its excellent capillary action allow the Daku Stabil-filter to draw water from areas with high water to areas with low water. This ensure sufficient and even water distribution throughout the roof.
· Water Storage/Low Maintenance
Daku element reservoir can store 16 litres of water/ m2. Together with the Daku substrate, The DAKU Roof Garden System can store up to 55 litres of water per m2. Watering cycles is therefore reduced.
· Drainage
Excess water is drained quickly and effectively through the patented channel system of the DAKU element. The danger of flooding in the substrate eliminated with the unique DAKU substrate.
· Lightweight
Daku extensive roof garden system is more than 40% lighter than a conventional roof garden. It is suitable for use on existing roof.
