The GRAF EcoBloc Flex is a versatile system, able to be used for stormwater infiltration, retention or rainwater harvesting. Shipping is cost-efficient, as the modular system’s two halves can be stacked, one inside the other.Even under very heavy loads, the EcoBloc system can be installed at a depth of up to 16.5 feet. Up to 14 layers are possible and the system can withstand a capacity of 60 tons. Note: the system size and load bearing can be adjusted individually to suit requirements of traffic and non-traffic areas. Designed to have high rate of percolation and barrier-free inspection,the EcoBloc has 4", 6" and 8" connections on all sides. 4" connections are positioned eccentrically at the side for complete de-aeration The system is easily cleaned by pressure washing and designed for a service life of over 50 years
