Common in Blackwood
What earthworks & drainage work has to deal with here
01
Rock close to the surface
Fractured rock sits shallow, so post holes and footings often hit stone early.
What Blackwood is built on
Shallow soil over fractured rock — augers meet stone early and often.
Hills drainage handles big winter volumes, springs that appear after rain, and gullies. Systems are sized for Hills rainfall and protected from blockage.
Building in Blackwood
Blackwood sits on the first serious rise of the Mitcham foothills, and its ground tells you immediately: rock is close to the surface almost everywhere. Post holes, footings and pool digs routinely hit stone, which is why experience with rock augers and hydraulic breakers is a prerequisite for working here rather than a nice-to-have. Big native trees define the suburb's character and are protected accordingly. The generation now buying Blackwood's 70s and 80s homes is rebuilding tired terraced backyards into something worthy of the views many of these blocks quietly hold.
Our approach in Blackwood starts with a level survey of where water enters, stalls and can legally leave. Connections to the legal point of discharge meet City of Mitcham requirements, and surfaces are reinstated over trench lines.
Rainfall (Foothills): roughly 600–800 mm a year (approximate long-term averages at nearby Bureau of Meteorology stations). Higher winter rainfall means run-off from upslope blocks is as much a design issue as summer watering.
