Project specifications
ECOVEGETAL install the green roof of the Roucas Blanc Olympic water sports stadium in Marseille, which will host the sailing events of the 2024 Olympic Games. This roof was planted with an endemic/local system based on the ENDEMIS PACA range of local plants. It is based on an enriched JARDILIGHT 1.1 substrate for enhanced water retention and better plant development. This type of substrate, composed of compost, expanded clay, pozzolan and terracotta, is used here for a semi-intensive roof. An AP32 absorbent mat and a DK20 drain are installed under the substrate to increase the water retention of the vegetated system. Watering is by remote-controlled drip irrigation. The architectural firms working on the buildings are : ROUGERIE+TANGRAM and CARTA REICHEN ET ROBERT ASSOCIES; - STOA (landscape architect); Owner: Marseille City Council; Contractor: TRAVAUX DU MIDI (Vinci Constructions); Project management assistance: SAMOP and CYCLADES; Waterproofing: SAB étanchéité; Irice - Effinature ;
