Almost certainly. Hawkesbury sandstone with rock close to the surface on ridge-and-gully ground. Sandstone is at or near the surface across the North Shore, so pools, basements and garage cuts are rock jobs from the start: sawn at the boundaries, broken in the middle, carted as rock. It’s in the quote from the first site look.
Vibration through sandstone is real and the North Shore blocks are close, which is why boundary edges are sawn rather than broken, hours are kept to council limits, and a dilapidation report on the neighbours is standard before work starts. Monitoring is set up where the engineer requires it.
Yes. Mini machines are craned over the house or walked through it, and rock comes out the same way in bins or by conveyor. Slower than a side-gate job and priced for it, but it’s how most lower North Shore pools get dug.
Yes, and it’s a common harbour-slope job. The rock is sawn at the house footing line and the boundaries and broken out in stages to the engineer’s underpinning and shoring sequence, so the house above stays where it is.
Yes, to the conditions. Most older North Shore streets are conservation areas where work near a listed house or a protected tree comes with conditions on the approval, and vibration near old masonry is watched closely. We dig to what’s approved.
