Geoplast products Drainroof and Drening in combination with sedum vegetation, provide a sustainable and cost-effective solution for a roundabout island design. Geocycle consists of three main layers. On the top is the sedum layer, which allows simple maintenance of plants and requires minimal nutrition. Sedum is placed in Drainroof trays that accumulate and retain rainwater, providing slow water release. The lowest layer is Drening, which creates high capacity dispersion and accumulation chambers, providing rainwater storage.
Green roundabouts improve the sustainability and resilience of urban design. Greenery is an important element of the traffic infrastructure because it improves air quality and reduces CO2 emissions. At the same time, green areas absorb rainwater and mitigate flood risks. Geocycle has zero hydrogeological impact that is particularly suitable in all urban areas which are subject to alluvial soil erosion. Sedum vegetation, which is able to withstand prolonged days of summer heat and long periods of drought, helps lower the temperature of the air in summer months.
Geocycle provides lower expenses in all phases, from installation to reduced operating costs. In the installation phase, there is no need for heavy machinery for the construction of layers. Since Drainroof and Drening are stackable, they do not require much space, which reduces both transportation and storage costs on the construction site. When completed, Geocycle has very low maintenance costs, since there is no need for frequent gardening, irrigation, or servicing. Strategic planning of green infrastructure is equivalent to savings in terms of emergency management and restoration of damage caused by catastrophic events.
