Terminal Building, Airport Ibiza/Spain

To enhance the visual appearance of the sur-rounding roof areas and therefore to improve the view from the waiting hall, the operator of the Ibiza Airport decided for a green roof. However, a weight restriction of approx. 20 lbs/sq. ft. (95 kg/m²) needed to be considered. Therefore the installers were forced to use a substrate that would guarantee a specific weight of only 53 lbs/cft. (850 kg/m³) but at the same time would provide an adequate nutrient supply. The growing media that was offered by the ZinCo associ-ated company Cubiertas Ecológicas S.L., met all these conditions. To ensure a balanced water and air supply drainage elements of the type Floradrain® FD 40-E were applied on the entire roof area before. The photographs prove the success of the works. Shortly after the completion of the landscaping works the vege-tation shows a covering of almost 100% - also due to the integrated drip irrigation.
