Background
Harvey Norman Property is the landlord of the Bendigo Homemaker Centre in regional Victoria. Over time, heavy rains caused erosion and partial collapse of the earthen bank along three sides of its property border, creating a potential erosion hazard as well as the obvious WHS issue to the roadway, assets and people below.
Brief
Ozy Services was briefed by Harvey Norman Property to scrape the loose soil from the embankment; to stabilise the 60° slope with an application of geotextile matting; to excavate and construct an agricultural drain with a sock and pipework at the base of the slope; then to design and construct a light retaining wall to run the full 500 metres of the bank to contain any further erosion.
Results
Ozy Services successfully;
- scraped and excavated the embankment of loose rocks and soil and carted debris from site to green waste depot,
- built a 500m agricultural drain complete with a geotextile fabric sock and slotted draincoil, then covered in filtration drain matting and blue metal,
- designed and built a 600mm high, light, timber retaining wall along the full 500m length,
- appelled the 60° slope of the embankment and pinned a biodegradable jute matting to stabilise the 4,000m² area
- mechanically swept the car park below to remove tonnes of rocks, soil and sand washed from the slope above
- These works remain under constant site observation by Ozy Services to ensure control of the everchanging environment.
