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.

Lining Cushion

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.

Not all geotextiles are created equal when it comes to cushioning performance and it is important to consider this when specifying these products.
