Modular, Stackable Water Containment: Rainstore3 by Invisible Structures

Designed by a landscape architect, Rainstore3 by Invisible Structures is a modular, stackable underground water containment system that is ideal for subsurface detention basins, retention and harvesting systems, rain gardens, green roofs, and sports field drainage. 

With 94 percent void space, Rainstore3 delivers nearly 25 gallons of water storage per unit — or up to 600 gallons at maximum stack height — without the need for gravel fill. 

Invisible StructuresMade with 100 percent recycled polypropylene (PP), the system’s modular design allows for flexible layouts and depths, making installation efficient and cost-effective, particularly in high-value urban settings where every square foot matters. 

By moving water capture underground, not only does Rainstore3 help project teams free up usable space above grade, but it also prevents soil erosion, decreases evaporation, reduces run-off and creates the potential for water re-use.
