RAINSTORE3 - Underground Water Storage System

Made From 100% Recycled Plastic

Rainstore³ is a modular, stackable, underground water containment system.

Designed by a Landscape Architect for both subsurface detention basins and retention/harvesting systems in 1999, Rainstore³ has since been used in a myriad of other applications such as water/rain gardens, green roofs and sports field drainage. With depths ranging from 4” to 7.9’, units arrive to the site preassembled for easy, drop-in installation.
Description and Applications

Each unit of Rainstore³ measures 1 m x 1 m x 0.1m high (3.28 ft x 3.28 ft x 4 inches). The compression fit units are stacked (if applicable) and sent preassembled to the construction site so there is no assembly required.
Making use of Invisible Structure’s trademark ring-on-grid design, Rainstore3 exceeds H-20 loading allowing it to support vehicular traffic, lightweight buildings or greenspace. An impressive 94% void space equates to almost 25 gallons of water storage per unit with no gravel fill required.
