Split faced concrete blocks are a popular facing for vertical reinforced soil structures. Phi Group design, supply and install a range of modular block reinforced soil systems, incorporating geogrid reinforcement and granular fill material, with a concrete block facing unit. Phi Group can provide the full design, supply and installation service, and have extensive experience working across a range of sectors such as highways, rail and commercial.
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 depending on the facing type, but generally for modular back faced reinforced soil structures it will be geogrid. The fill material is typically an imported 6I/6J granular material, but testing is required to prove suitability.
