Climate action charity Possible has created a self-watering ‘green’ roadblock to help cities’ with their Covid-19 emergency transport plans. The roadblocks are designed to prevent the predicted surge in post-lockdown motor traffic from overwhelming UK city streets. Working with specialist civil engineering firms and horticultural experts, Possible’s innovation team adapted standard concrete roadblocks to embed high-tech rainwater reservoirs beneath recesses planted with a selection of drought-tolerant species.
Designed to capture and store rainfall naturally, the ‘Concrete Jungle’ blocks can keep their plants supplied with water for up to six weeks between rainfall events.
