Stormwater Storage

Using GreenBlue structural support modules for stormwater storage is a cost-effective alternative to stormwater tanks. They are load-bearing for pedestrian and vehicular traffic, and are extremely versatile and able to accommodate any design configuration.


Rated for maximum vehicular traffic with minimal surface, GreenBlue Urban stormwater storage modules are the strongest large underground modules, while providing the most void space for stormwater storage on the market (at over 97%), allowing you to reduce excavation costs while maximizing storage volume. The modules are simple to install and limitless in their configuration in order to accommodate subsurface infrastructure such as utilities and services.


  • The most cost-effective underground stormwater retention/detention system
  • Over 97% void space
  • Exceeds AASHTO H20 rating for vehicular traffic with minimal surface
  • Provides approximately three times more volume than a stone mixture
  • Can be used under any surface including permeable and impermeable
