Process
As the granular material is being placed in layers, reinforcement is incorporated within this material to provide additional strength. The type of reinforcement can vary for the concrete panel ‘Reinforced Earth’ structures. The two options are galvanised steel or geosynthetic straps. The fill material is typically a 6I/6J granular material, but testing is required to prove suitability.
