Excavation & Earthworks Dover Heights

It depends on the volume of material, the ground (hawkesbury sandstone with rock close to the surface on the coastal cliffs), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.

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.

A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.

Yes. Hawkesbury sandstone with rock close to the surface on the coastal cliffs. On the headlands and the harbour slopes sandstone is at or near the surface, 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 site look.

Yes, 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 and the neighbour’s house stay where they are.

Yes. Mini machines are craned over the house or walked through it, and spoil 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 Eastern Suburbs backyards get dug.

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.

Yes. Hawkesbury sandstone with rock close to the surface on the coastal cliffs. The pool builder’s engineer will usually want the base checked, which is standard, and the machine is sized to the side access.
