On the Cumberland Plain, Potts Hill ground runs to Wianamatta shale over reactive clay, near Potts Hill reservoirs. Because Potts Hill sits flat around Duck River, drainage is designed into the cut and the pad is trimmed dead level. Around Sefton, the clay is reactive, so fill goes in in compacted layers.
Potts Hill is in City of Canterbury-Bankstown; the Potts Hill reservoirs end carries no overlay, so cut and fill is DA or CDC work. The crew reaches the Potts Hill job off Chapel Road or Waldron Road, past Birrong.

Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.

Rarely on the flat streets. Wianamatta shale over reactive clay on the Cumberland Plain. Shale under the clay is ripped rather than broken. The rock in this region is on the Georges River side, not around Bankstown and Canterbury centres.
Yes, and Canterbury-Bankstown is the busiest duplex market in Sydney. The old house down, slab and footings out, the block stripped, and two pads cut and compacted to the engineer’s spec, with the shared driveway boxed out at the same time.
It’s one of the easiest councils for it, and the 50s and 60s blocks have the room. A mini excavator through the side access, the pad cut level and compacted on the clay, and the service trenches run at the same time.
Reactive clay. It swells in wet winters and shrinks in dry summers, and anything poured on loose or uncompacted fill moves with it. A pad cut and filled in compacted layers to the engineer’s spec is what stops the new slab doing the same thing.
Yes. The old house down, slab and footings out, the block stripped and the new pad cut and compacted, as one run if you want the demolition handled too.
