Segmental Masonry Block Soil Reinforced Retaining Wall and ACEGrid® Geogrid

The project

With large parcels of land now becoming a premium for companies looking to build within the Brisbane area, land is being acquired by developers North, South, East and West of the CBD to accommodate the industrial growth happening within the South East Qld corner of the state.

Not all parcels of this acquired land are perfect however, which means a significant amount of earthworks are required to shape and retain the land prior to building works commencing.

One area of land to the West of Brisbane’s CBD required retaining structures to be constructed to accommodate the client’s large warehousing facility.

The solution

In this project at Heathwood, a segmental masonry ACEGrid® polyester geogrid soil reinforced block wall was adopted as a very effective and economical solution for the 4.4m high wall.

ACEGrid® is manufactured from high tenacity polyester (PET) yarn and is an approved product for State Road Authorities in Australia. Trusted by a wide variety of consulting engineers and contractors, this engineered woven geogrid has exceptionally high strength characteristics at low levels of strain.

For this project, the design life for the structure was to be 120 years, and the Global Synthetics products selected for this wall were able to meet and achieve the 120 years design life as requested by the designers. ACEGrid® GG60 and ACEGrid® GG120 were selected for the wall reinforcement to achieve the required long term design strength.

In total Global Synthetics supplied 15,000m2 of ACEGrid® GG60 and ACEGrid® GG120. Using these strong and reliable geosynthetic products, 1422m2 of wall face was constructed, providing reinforcement and strength for decades to come.
