In April 2015, Concrete Canvas GCCM was used to line a ditch next to the new Bexhill to Hastings link road.
South Australia Cricket Association (SACA) and Adelaide City Council recently collaborated on the redevelopment of Narnungga (Park 25) which will include a new multi-purpose sports pavilion to replace the existing sporting clubhouses, improved cricket and football fields and a floodlit beach sports facility.
One of the biggest issues historically with the football/cricket field had been its undulating surface and poor drainage. This was in part due to the clay type soils typical of this region coupled with poor natural drainage. Therefore one of the most important aspects of the project was ensuring that the drainage was significantly improved to ensure excellent ongoing playing conditions during the wet and dry season for both SACA and the local South Australian Amateur Football league.
Thomas Malthus, author of An Essay on the Principle of Population, is often ignored or derided today. The general commentary on Malthus goes something like this: “oh yeah, isn’t he that guy that predicted we were all going to starve because the population was increasing faster than the rate of food production… what a fool to not predict all the technology that allows us to keep growing”. Indeed, the world population at the time of publication, 1798, was about 1 billion and today the estimated population is 7.5 billion. What an achievement!
Polyethylene geomembranes are used in dams, landfills and tailings dams as the primary hydraulic barrier to separate contaminants from groundwater. Logic would suggest liner design would therefore include hydraulic or permeability values for these products, but these are not seen in project specifications. The explanation is that if you ensure that the geomembrane PE formulation meets site conditions, and ensure that certain basic mechanical properties are met with emphasis on thickness (1.5–2.0 mm+), then permeability through the liner can be assumed to be extremely low. It is design analysis of potential holes and liner stress post placement that determines hydraulic performance and good design requires an understanding of these potential damage mechanisms.
Innovation is hard. To do it well, you need to have a clear picture on where you are heading and how you are going to get there. You need to coordinate a shared vision, cross functional teams, product development and a sales strategy and all of this needs to fit within an existing structure, somehow nestling it's way into the small openings of time that most employees simply do not have.
Geofabrics New Zealand Ltd are pleased to announce the completion of the New Zealand Transport Agency (NZTA) approval process for all our Geosynthetic Reinforcing products which meet clause 6.8.1 of the Bridge Manual 3rd edition of the NZ Transport Agency’s Bridge Manual.
Not all geotextiles are created equal when it comes to cushioning performance and it is important to consider this when specifying these products.
Geofabrics Australasia Pty Ltd (Geofabrics), the Australasian leader in geosynthetics, today entered into a distributor agreement with Concrete Canvas Ltd (Concrete Canvas), the inventors of the innovative Concrete Canvas® Geosynthetic Cementitious Composite Mat (GCCM).
Approved by Network Rail in the UK and national rail authorities across the world, Tensar TriAx geogrid is specifically designed for use in track beds.
In 2014/15 over $1 billion was spent by Australian rail asset owners and operators on track maintenance works. However, a recent report prepared by industry leading cost consultants, WT Partnership, has shown that a reduction in maintenance costs can be achieved if asset owners and operators embraced innovative geosynthetic solutions to reduce whole of life costs.
BIS Shrapnel’s Engineering Construction in Australia 2016 – 2030 September 2016 update highlighted two significant events in the Australian Engineering Construction sector: Transition of the mining and resources segment from Capex to Opex and a move by state and federal governments to invest in road and rail transport infrastructure following the 2011 to 2015 trough in public sector investment.
Gabion structures have been around for well over 100 years and in the 21st century Maccaferri gabions have been used to build structures over 70 m high. Double twist (DT) mesh gabions can be used in many applications from architectural to structurally sensitive projects.
Anyone who uses the road infrastructure in Australia also makes a small contribution to what are known as road-deposited sediments (RDS). The contribution of one individual is insignificant but the net effect of all of our combined road use results in a significant amount of waste material. What are road-deposited sediments? Road-Deposited Sediments are small particulates that accumulate around our road infrastructure.
The ferocious storms which pounded the NSW and Southern Queensland coasts last weekend brought into focus the Climate Council's 2014 report Counting the Costs: Climate Change and Coastal Flooding.
The report predicts that more than $226 billion in commercial, industrial, road and rail, and residential assets around Australian coasts are potentially at risk by 2100 due to rising sea levels and climate change. The report also calculates that 52% of Australia's coastline is susceptible to recession due to climate change, rising sea levels and storm surges.
In two instances along the coast Council and landowners have worked to proactively protect their beachfront from the effects of climate change; protecting their beaches from the impact of last weekend’s storms.
Geofabrics has been awarded Australian Manufacturer of the Year at the 2016 Manufacturers' Monthly Endeavour Awards in the Industrial Products category for our Trinet® and Flownet® geonet geocomposite drainage systems.
