Retaining Walls in Blackwood
Retaining Walls in Blackwood — designed and built for this suburb's actual conditions by a team that works its streets regularly. Blackwood isn't a generic Adelaide postcode to us, and this page explains how its ground, housing and rules shape the work.
What Blackwood is built on
Shallow soil over fractured rock — augers meet stone early and often. Every quote we write in Blackwood starts from this.
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.
Retaining in Blackwood is shaped by two local facts: foothills ridge-and-gully country, with most blocks sloping in at least one direction, and shallow soil over fractured rock — augers meet stone early and often. Both feed directly into how we design a wall here — footing depths, drainage volumes and post spacing are engineered for the ground the wall actually stands in, not a generic spec sheet.
Around 1960s–80s family homes on big treed blocks, steadily being renovated by a new generation, we most often replace older walls that were built before current engineering standards — and where a boundary fence rides on top of the wall, we rebuild both as one job so heights, sight lines and neighbour arrangements are resolved once. Where a wall retains more than a metre, development approval is lodged with City of Mitcham before work begins.
