Case study: massive voids
The Suter Pier project at the Port of Townsville, Queensland, Australia.
Beneifil was injected from above and behind the wall at the rear to encapsulate the rocks and fill the voids under the shed floor.
All the time ships were berthing, unloading and loading at the cargo wharves that run along each side of Suter Pier Shed. There was virtually no interruption to the workings of the Port.
For this work Benefil was produced at a relative gravity of 50 kg per cubic metre to suit the high floor-loading requirement. (The density can be varied to suit other tasks: relative gravity of 22 kg/m3 suits the filling of fuel tanks that are to be made safe for abandonment and relative gravity of up to 70 kg/m3 may be produced to support heavier structures). Combining economy, ease of application, lack of disruption and engineering strength, Benefil was the right answer to the demands of this Townsville Port work.
