Part of Graf UK’s market-leading EcoBloc range of stormwater systems, the EcoBloc Maxx is completely modular and made from expertly designed plastic cells that fit seamlessly together to build a tailor-made stormwater solution.
Its innovative design not only allows for complete ease of installation, but provides high storage volume and is conveniently stackable – minimising transport costs, CO2 emissions and storage space in stock.
The tanks can be made to any shape or size and can be positioned as shallow or as deep underground as required, without taking up valuable surface area.
For stormwater attenuation, EcoBloc systems can be surrounded by an impermeable membrane to prevent any water from escaping the system unchecked. This allows for ultimate control of water back into the surface water drainage system and water courses.
For rainwater infiltration purposes, the system can be covered in a permeable geotextile, allowing water to be gradually released back into natural groundwater reserves.
EcoBloc Maxx has a heavy-duty lorry-bearing capacity of 40 tonnes, and even under extreme loads boasts a storage coefficient of 96%. With a gross volume of 225 litres, EcoBloc Maxx modules hold three times the storage capacity of a typical gravel infiltration ditch, while their compact design requires minimum space and soil excavation.
