ACO StormBrixx®
StormBrixx is a geocellular stormwater storage solution designed to maximize capacity in areas with depth or space restrictions. Its modular, brick-bonding design ensures stability, while lightweight construction simplifies installation alongside existing utilities. Built for durability with a 50-60 year design life, StormBrixx offers reliable water management that reduces excavation needs and provides long-lasting performance in urban and industrial environments.
Along with general use, ACO StormBrixx excels in applications with unique requirements, such as:
- Applications with High Water Tables
- Restricted Depth Applications
- Restricted Footprint Applications
Advantages of a Geocellular Stormwater Storage System
ACO StormBrixx provides a reliable alternative to chamber & stone systems, concrete vaults, and corregated metal pipes, with several benefits to consider.
- Versatile with lightweight, stackable components for ease of shipping and handling
- Sustainable polypropylene components designed for quick and simple installation
- Robust Design through tank brick-bonded formation
- Durable material and build, strong enough to last 50-60 years
- Compliant to AASHTO HS-20 and HS-25 load conditions
- Convenient open space and structural pillars allowing for simple access
- Efficient use of space, with void ratios of 93.8-96.5%
Versatile and Sustainable
The lightweight, stackable components of ACO StormBrixx offer a variety of assembly options to form an open, bonded structure. Each polypropylene component is designed for quick and simple installation, significantly reducing project timelines.
Highly Robust Design
ACO StormBrixx systems are formed via brick-bonding, where top and bottom Half-Modules are placed and connected perpendicular to one another. This design creates an interconnected system that optimizes load transfer from top to bottom. ACO assists by providing detailed layer orientation drawings with your project in mind.
Further layers of Full-Modules can be stacked on top of each other and connected via Layer Connectors.
Durability and Compliance
Manufactured in the USA, every component of ACO StormBrix meets rigorous
AASHTO HS-20 and HS-25 load conditions (see table on pg. 6). Each system provides a reliable and enduring stormwater management solution, aligning with sustainable intrastructure goals.

HydroCAD Support
HydroCAD provides built-in support for modeling the ACO StormBrix® chamber system.
NJDEP/NJCAT Testing
The ACO StormBrixx Sediment Filtration Tunnel New Jersey laboratory tests available here.
Highly Customizable Build
ACO StormBrixx tanks can be built to suit specific depths and circumvent existing infrastructure, such as wiring, piping, pillars, or entire buildings.
Brick-Bonded Structural Strength
Interconnecting half-layers of ACO StormBrixx in different patterns substantially increases the overall structural strength of the tank.
Lightweight, Durable Material
ACO StormBrixx components are easily transported and carried. Once installed, design life is 50-60 years depending on the system.
AASHTO HS-20/HS-25 Compliant
Minimum lightweight yet durable wall thickness. Components are easy to handle and manipulate during staging and installation.
Stackable Components
ACO StormBrixx modules, side panels, and other components stack within themselves, significantly reducing storage space.
High Void Ratio
Void ratios of 93.8-96.5% are possible due to hollow pillars and minimal surface area within an ACO StormBrixx tank.
Ease of Access
Inspection and maintenance are performed from access points that are preplanned to provide access to the entirety of an ACO StormBrixx installation.
Suits Depth Requirements
ACO StormBrixx 300, 600, and 900 provide variable tank heights, which can be further manipulated with multiple layers, half-layers, and 900+300 tanks.
Sediment Tunnel Option
Confirmed to capture 82.7% of total suspended solids when designed as suggested by ACO.
