EcoBloc Maxx is a modular geocellular unit designed for below-ground stormwater attenuation or infiltration (soakaway) systems.

Each unit can be easily stacked and connected to form an underground tank that either temporarily stores excess stormwater or allows gradual infiltration into the ground.

This flexibility supports Sustainable Urban Drainage Systems (SUDS) by easing pressure on surface water infrastructure and promoting responsible water management on domestic or light commercial sites.

With a storage volume of 225 litres per unit and a load-bearing capacity of up to 60 tonnes, EcoBloc Flex modules are lightweight, easy to install, and suitable for use beneath driveways, lawns, or paved surfaces.

Approximately 4.5 crates are required per 1m³ of storage, making them a compact and cost-efficient solution for attenuation and soakaway applications.
