Excavation & Earthworks Matraville

It depends on the volume of material, the ground (botany sand beds over sandstone with a high water table), 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.

No, it’s sand. Botany Sand beds over sandstone with a high water table. The old dune country from Bondi to Botany Bay is deep marine sand, 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 beachside 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.

It can, which is why the councils control it. Dewatering in the sand country is planned from the geotech, kept to the approved rate, and monitored so the neighbours’ ground doesn’t settle. We flag it at the site look and price it in.

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.
