Roof Garden with Aquatec® – for Roofs with a Limited Load Bearing Capacity

Up to now, light-weight solutions were only possible in the field of extensive green roofs. However, with the system build-up “Roof Garden” with Aquatec® AT 45 the balancing act between “light-weight” and “intensive” can easily be mastered. It allows for visually appealing prestigious designs with lawn, perennials and small shrubs even on roofs with a low load bearing capacity. The system build-up is applicable on 0°-roofs as well as on roofs with an inclination of up to 5°, including inverted roofs.

Sophisticated irrigation concept

The irrigation takes place via special Dripperlines inserted into the Aquatec® elements which are supplied with water by the Irrigation Manager BM 4 as required. Due to the fact that water is being distributed evenly within the Aquatec® elements and brought to the plants via the wicks of the Wicking Mat, the water consumption is comparatively low.The water storage capacity of the Aquatec® elements ensures a maximized retention and supply even during hot and dry periods.

Lower substrate height

Due to this sophisticated kind of irrigation substrate depths can be reduced up to 50 % in comparison to other intensive build-ups which results in a lower system weight. Furthermore the Aquatec® elements do not require an infill as some other build-ups which also contributes to reduction in material requirements, installation costs and weight.
