Full Scale Trial – Rock Bag Stability Test
In September 2022, Project Material Pty Ltd engaged with industry professionals to conduct the worlds first “full scale” rock bag stability test. The research was conducted in Brisbane Australia.
The overarching aim was providing industry with an independent assessment on the performance of Rock Bags as an alternative to conventional rock armor which is typically utilized to provide scour protection against wash generated propulsion units from ships and tug vessels.
Globally, shipping ports and marine environments experience regular high velocity water flows causing 100’s of millions of dollars of damage, remediation and maintenance each year.
Rock Bags are considered novel in the application of erosion and scour control thus little to no testing was available for engineers and environmental consultants to understand how rock bags performed under high velocity flow.
The full scale trial was emulating the stability of 2, 4 and 8 Ton rock bags in various configurations.
The attached report written by AMC Search Tasmania (Australian Maritime College) contains the findings of the trial, however please feel free to request further information regarding the report, trial and products. The research paper has also been presented at PIANC conference in Queensland 2023 by AMC Search.

Complimentary to the report, this video clip provides visuals of the highly turbulent water generated from the tug boat thrusters. Over the course of 3 days, rock bags were moved into a variety of configurations including a 4m high vertical stack with maximum propulsion to encourage failure, however this effort was futile !
