ACO StormBrixxGeocellular Storage
ACO StormBrixx is a plastic geocellular (modular tank) system for stormwater detention, retention, and infiltration. A single recyclable polypropylene body assembles into an open 3D structure using a patented combination of brick-bonding and cross-bonding — one of the strongest geocellular systems available — while 3-dimensional access enables CCTV inspection and jet cleaning along the base. See it alongside other options on our detention systems page.

Product Specifications
StormBrixx Systems
StormBrixx 300
AASHTO H-20 / HS-25 loading for typical commercial detention, retention, and infiltration applications.
StormBrixx 600 HD
Heavy-duty body rated AASHTO H-25 / HS-25 for high-traffic areas and heavy vehicle loads.
StormBrixx 900 SD
Standard-duty body rated AASHTO H-20 / HS-20 for cost-effective, lower-cover installations.
Detention, Retention & Infiltration
The same StormBrixx modules deliver any of three stormwater functions depending on how the structure is wrapped.
Infiltration
Wrapped in geotextile so collected stormwater soaks into the surrounding ground, recharging groundwater.
Detention (Attenuation)
Wrapped in an impermeable membrane so runoff is held and released at a controlled rate to meet discharge limits.
Retention
Stores water for reuse and rainwater harvesting, supporting LID/SUDS and green-infrastructure goals.

Where StormBrixx Fits
Geocellular storage is the underground side of stormwater management. See the product category and the site types where StormBrixx detention, retention, and infiltration are designed in.

- Detention & retention systems — compare StormBrixx with chamber-style storage.
- Catch basins — pre-treatment inlets that feed the storage field.
ACO StormBrixx FAQs
Common questions about ACO StormBrixx geocellular storage systems
ACO StormBrixx is available in three variants: StormBrixx 300 (standard duty, H-20/HS-25 loading), StormBrixx 600 HD (heavy duty, H-25/HS-25 loading), and StormBrixx 900 SD (standard duty, H-20/HS-20 loading). Each variant is designed for specific load requirements and applications.
The patented brick-bonding assembly provides exceptional structural stability by interlocking modules in a staggered pattern similar to brick construction. This creates a monolithic structure that distributes loads evenly and resists movement.
Yes, ACO StormBrixx is compatible with infiltration, detention, and retention applications. The system can be wrapped with geotextile fabric for infiltration or lined with an impermeable membrane for detention/retention based on site requirements.
StormBrixx modules are manufactured from recyclable polypropylene, making them an environmentally sustainable choice. The material provides excellent chemical resistance and long-term durability in underground applications.
StormBrixx features 3-dimensional access for inspection and maintenance. The open structure allows for camera inspection, jetting, and vacuum extraction from multiple directions to ensure long-term system performance.
