Recommended Installation

Concentric ring layout

A series of ever decreasing rings converging towards the center of the system. Place in a brick bonded method. Repeat for subsequent layers using the connectors to bond layers to one another.

Installing the side panel

Polypropylene side panels are added to the perimeter of the system to give lateral support against surrounding soils. The side walls have a predefined saw matrix for the connection of plastic pipes of 4-12” (100-300mm), which can be cut out using a jigsaw.

Installing the top  cover

Polypropylene top covers are added to the top layer of the system to fill the openings of the pillars and to ensure consistent support for the cover fill material.

Note: Covers are only built into the top layer of the basic elements, before the fleece is wrapped around them.

Installing the side panel

When installing the side walls you must ensure that the positioning tab is inserted into the base element first.

The outsides of the infiltration system must be covered with side walls, which are inserted into the openings provided in the basic elements and click into place. The side walls create a perimeter for the entire system offering a clean base surface for the geotextile wrapper. If needed, a pipe connection point of Ø4”,6”, 8”, 10” or 12” (100, 150, 200, 250,or 300mm) can be cut out along the cutting/sawing marks in locations provided. Side walls have a predefined saw matrix for the connection of plastic pipes.

Installing the top  cover

A single ACO StormBrixx cover closes off four pillar openings.

To ensure the geotextile wrapped around the system fits snugly, covers should only be inserted in the top layer of the infiltration block. They prevent the fleece being forced into the necks of the pillars during backfilling.

Note: Covers are only built into the top layer of the basic elements, before the fleece is wrapped around them.

Layer connectors - required when multiple layers are used

Installation of connectors

When installing a single layer of brickbonded StormBrixx, connectors are not an essential requirement. If the units are fully brick-bonded, the structure will not need the connectors to hold the system together. Connectors will be provided as a precaution and extra installation strength. This is unique to StormBrixx as other StormWater control systems require these units to ensure structure is fully stable during backfill and to ensure their design life can be achieved.

Installing multiple layers

When installing a second layer to an ACO StormBrixx construction, connectors will be required. Connectors should be installed around the outside of the structure and sporadically through the center. Further connectors should then be installed into the first set to create a locator for the second layer.

Minimize lateral movement

These two connectors should protrude from the top of the structure by approximately 1-2” (30-50mm), depending on which unit is used. These protruding units fit the base of the second layer and are key to minimising lateral movement during backfill and overall installation
