StormBrixx Range Surface water infiltration and storage

ACO StormBrixx is a unique and patented plastic geocellular stormwater management system

Its versatile design allows the system to be used in applications across all construction environments as a standalone solution or as part of an integrated sustainable urban drainage (SuDS) scheme.

The patented brickbonding and cross bonding feature provides a strong, long term installation and also helps to improve the construction speed of the tank.

ACO StormBrixx simplifies delivery, site logistics and installation as a result of its stackable design. For each delivery of StormBrixx, up to 4 loads of competitor product may be required, making StormBrixx approximately 75% more efficient in delivery.

The range consists of StormBrixx SD (standard duty) and StormBrixx HD (heavy duty) stormwater management systems.

Key benefits

Access and Maintenance

The whole system, including all the extremities can be inspected and maintained from just a few access points thanks to the open cell structure.

Simplified handling and logistics

Each single injection moulded body nestles optimising logistical and installation costs, thus helping to reduce carbon footprint of the system.

Structural Integrity

The patented brickbonding and cross bonding feature enables strong, long term installation and improved construction speed of the tank.

Easily Configurable

The StormBrixx system is easily configurable, so a solution can be achieved even on the most challenging of sites.

Stormbrixx Overview Video

Stormbrixx - 1 Minute Overview Video

This short video will give you the basics of the ACO Stormbrixx system. This includes it's many features:

  • Access and Maintenance
  • Simplified handling and logistics
  • Structural Integrity

StormBrixx SD

StormBrixx SD is suitable for use in a wide range of construction applications

  • High porosity of 97%
  • Depth to invert of 4.5m
  • Includes access plates for CCTV and jetting equipment
  • 347 cubic metre capacity per truck delivery

StormBrixx HD

StormBrixx HD- The heavy duty stormwater tank is designed for where installation depth and access requirements are of greater importance to the project. It has Man access units for the more comprehensive maintenance requirements of Local Authorities and water companies.

  • Depth to invert of 6.0m
  • Available with Man access units
  • BBA Certification
  • Porosity of 95%
  • 309 cubic metre capacity per truck delivery

StormBrixx System

For both systems the open cell structure allows easy access for CCTV and jetting equipment, enabling the whole system, including all the extremities, to be inspected and maintained from just a few access points.

The ACO StormBrixx system consists of a single recyclable polypropylene piece that can be assembled in a variety of ways to form an open bonded structure.

ACO StormBrixx’s unique pillar configuration gives a high porosity up to 97%. This minimises the excavation required to achieve a specified storage capacity, reduces the aggregate needed for backfilling, and improves the flow characteristics of runoff through the installed tank.

Side panels are added to the perimeter of the system for lateral support and top covers are added to ensure consistent vertical support for the cover fill material. 

Additional accessories available for both ranges include inspection point and pipe connectors, geotextiles and geo-membranes, as well as a 600 x 600mm access chamber for full inspection and maintenance for the StormBrixx HD.

ACO StormBrixx can be configured to minimise silt accumulation and has the added feature of a low flow and drain down facility ensuring that the system can be properly maintained throughout its life.

Designed and manufactured in accordance with CIRIA C680.


  • Can be assembled in a variety of different tank configurations to satisfy installation and site requirements
  • Silt management and control achievable through tank configuration layout
  • A 1200mm x 1200mm concrete man access chamber for the StormBrixx HD provides easy man access for through inspection down each of the system’s pathways. Built to suit the size of the system and can be located at various points
  • Bonded stacking for optimum stability
  • Low flow, draindown and silt management facility
  • Environmentally efficient solution, minimising carbon emissions in manufacture, transportation and on-site assembly
  • High void ratio minimizes excavation volume
  • Fully certified performance
  • Manufactured from recycled and recyclable polypropylene
  • Suitable for all industrial, commercial and residential applications including access roads.
  • Clip-in 3 way connector and the crossbonding feature permits off site construction of the system
  • Top covers support infill material


  • The patented brickbonding and crossbonding feature delivers a strong and robust tank installation
  • The open cell structure provides simple access for remote CCTV and maintenance equipment to inspect all levels and areas of the system
  • The stackable design reduces transportation costs and improves the carbon footprint of the product. For a 280m3 storage volume project requirement, ACO StormBrixx can be transported on a single vehicle.
  • The system has a unique ‘draindown’ facility – a simple access and clean feature of the tank (Attenuation only)
  • Access chamber provides access for cleaning, large pipe diameter inlets and silt management
  • Delivery, site logistics and installation are all dramatically simplified, as a result of the system’s ‘stackable’ design
  • A clip-in 3 way connector improves the structural integrity of multi-layered tank structures and where brickbonding is not used
  • Inspection point for camera or jetting equipment
  • Clear column ‘pathways’ simplify cleaning
  • Smooth surfaces prevent silt build-up
