Epic project adding a green roof to the architecturally designed Orange Regional Museum - we loved working on this project and get to drive past it at least once a day in Orange.


In certain sections, the roof slopes at angles of up to 23 degrees and as such a sophisticated anti-erosion strategy was put in play to stop the soil and turf running down the hill.


Four material layers were installed on the roof even before the soil was pumped on. A waterproofing layer went on top of the slab and was then followed with geo-tech fabric, an egg-shell type drainage layer and another layer of filter fabric to control and slow water runoff.


Soil prep work for Orange Museum


In the steep sections, open drainage geo-webbing was used to support the soil while the turf laid its roots over a six week period. Months on since its installation the green roof is healthy, stable and now open to the people of Orange as a new public green space and vantage point across the city.
