Stormwater management

ABG design, manufacture and supply a full range of system components for rooftop and podium-level stormwater attenuation projects.

We work with the project architects and building engineers to calculate and supply all the materials required above the waterproofing layer to meet the surface water reduction or discharge consent limit.

The system components encompass the drainage board / reservoir layers, filtration, protection and separator geotextiles, void formers, inspection / restrictor chambers, growing media and planting.
