Create a bio-retention profile using the powerful Rockslinger machinery.
Bio-retention basins are design to filter sediment and contaminants out of stormwater flow. 
Stormwater is collected into the treatment area which will generally have grasses, sand, and organic layer, planting media, and plants. 

Option 1:


Use our Rockslinger® machinery to install BIO-GRO® - a complete bio-retention profile from Benedict Sand & Gravel.
Scientifically-tested, BIO-GRO® has been designed to comply with the
Adoption Guidelines for Stormwater Bio-filtration Systems (CRC WSC 2015).
The profile comprises three individually manufactured layers with the necessary characteristics to enhance hydraulic conductivity and
ensure optimal bridging. BIO-GRO® - tested and engineered to exceed your specifications.
For more information call BENEDICT on (02) 9986 3500 or visit their bio retention page.

Option 2:

Use your own bio-retention system and we will install it through the Rockslinger® machine.
