With geotextiles and geogrids becoming ever more popular and integrated in a wide variety of civil works, it is easy to become complacent as to the selection and use of geosynthetics.

Sleeve-It is a game changer because it shifts the current way we design and build fences on SRWs. Sleeve-It is made from 95% post-consumer recycled polypropylene.

There is a lot of benefit to a contractor to win a reinforced soil project. However, we must realise that there is a high level of skill required. They will need to be familiar with the required design outcomes, and understand the importance of the compaction levels, required fill types, drainage detailing and facing construction to name a few.

Once again, we find ourselves deep in the middle of winter with the weather pounding our road networks and coastal areas, and many parts of the country experiencing saturated ground conditions.

Erosion and sediment control are two distinct though related processes. Erosion control is preventing the washing away of soil particles by the action of wind or rain, while sediment control relates to controlling or containing the sediment laden water once erosion has taken place.

Road closures and delays on our state highways and regional roads following storm events seem to be more common than ever. Some of the big events hit the headlines and cause major delays over days or even weeks, while dozens of smaller slips go unnoticed by the media but still cause untold headaches and delays to road users nationwide.

What is extensible reinforcement in a bridge abutment or MSE Wall? It sounds like we are trying to build with some stretchy rubbery product. However Inextensible reinforcement sounds more like it. Nice and strong, and it won’t stretch. Now is that the case?

The term Urban Heat Island (UHI) refers to the fact that urban areas are hotter than rural areas due to human activities, in fact, Cities are on average 2˚C hotter during the day than rural areas, and as much as 5.5 ˚C hotter at night.

There are many options when considering a product for base stabilisation and reinforcement of roads, foundations and working platforms so which is the best solution for the many scenarios?

The use of geogrids in pavements and foundations is well established now and the benefits would be known by most engineers and roading contractors. However, are you clear on which geogrid type to use, and whether a triaxial or a biaxial geogrid will be best for your application?

For many years you have likely heard of the benefits of geosynthetic reinforcement in road pavements, and maybe even experienced it first hand, but there have been very few tools that allow us to incorporate these known benefits in to a pavement using actual test data and reputable methodologies.
