Excavation & Earthworks Kurnell

It depends on the volume of material, the ground (coastal sand dunes over sandstone on the botany bay headland), 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.

Not on the bayside flats. Coastal sand dunes over sandstone on the Botany Bay headland. From Kyeemagh to Sans Souci it’s sand over old bay deposits, and the problem is water and stability rather than rock: the dig is shored and dewatered instead of sawn and broken.

Yes, it’s the standard bayside pool. Sand walls don’t stand, so the dig is shored with trench sheets or battered, the water table is pumped from a sump to the council’s dewatering rules, and the shell goes in fast once the hole’s at level.

Yes. Through St George it’s the most common job: the old house down, slab and footings out, the block stripped, and two pads cut to the engineer’s spec, in clay on the ridge top and into sandstone where the design goes deep.

Yes. Mini machines are craned in over the house or walked through it, rock is broken out and craned or barrowed away, and on the Port Hacking and Georges River blocks a barge is sometimes the answer. Slower than a side-gate job and priced for it.

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.
