High Volume Water Storage.
Easy Installation.

PaveTank offers the GRAF EcoBloc Maxx storage system for stormwater infiltration and retention solutions. This modular storage system has an HS-20 vehicle loading rating. Modules with baseplates can be stacked in multiple layers and mechanically connected to form almost any configuration – creating one of the lowest cost per cubic foot of underground storage available.

For infiltration applications, a permeable geotextile layer is wrapped around the PaveTank system allowing the stormwater to gradually drain back into the ground in a controlled manner. For water storage and reuse applications, an impermeable membrane is added between two layers of geotextile fabric. Made from 100% recycled material, the eco-friendly stackable modules save space, transport costs, and CO2 emissions.
