ACO StormBrixx



ACO StormBrixx is a unique and patented plastic geocellular stormwater management system. Designed for surface water infiltration and storage, its versatility allows it to be used in applications across all construction environments as a standalone solution or as part of an integrated sustainable urban drainage (SUDS) scheme.

ACO StormBrixx addresses the fundamental requirement of access and maintenance for SUDS Approval Boards (SABS) and water companies, whilst retaining the structural integrity of the installation.

The open cell structure permits completely free access for CCTV and jetting equipment which allows the whole system, including all the extremities, to be inspected and maintained from just a few access points.

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. Each single injection moulded piece nestles, optimizing logistical and installation cost significantly, helping to reduce the carbon footprint of the product.

The ACO StormBrixx system consists of a single recycled 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 void ratio of 95%. 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 include inspection point and pipe connectors, geotextiles and geo-membranes, as well as a 600 x 600mm access chamber for full inspection and maintenance.

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.
