Located in a tropical climate with high intensity rain events, the stadium required a drainage system that could cope with extreme rainfall over a short period of time.
The installation consisted of Megaflo Green socked slotted drain pipe as the main trunk lines with 300mm and 450mm panels running along the length and the circumference of the field.
Connecting into these main trunk lines are the 170mm panels laid in a herringbone pattern, intercepting all water through the sports field. The whole system feeds into Megaflo panels that circumnavigated the field and empty into a series of concrete pits.
The installation contractor elected to lay Bidim Green non-woven geotextile as a separator prior to installation of the Megaflo. The panels were held in place utilising soil nails installed through the panel slots into the ground; an effective technique that prevents the panels from moving as other connections in the line are added.
Once installed, the Geofabrics Australasia team visited the site to ensure the head contractor and sub-contractors were satisfied with the result of the Megaflo system before any filtration medium and turf was backfilled.
The final layout provided an excellent example of a complex Megaflo system created to maximise playing hours and meet the designer’s requirements.
