Excavation & Earthworks Mortlake

It depends on the volume of material, the ground (river alluvium and reclaimed flats over shale near the cooks and parramatta rivers), 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 usually in the first metre on the flat streets. River alluvium and reclaimed flats over shale near the Cooks and Parramatta rivers. Shale under clay is ripped rather than broken, and old fill is the more common surprise than rock.

Yes, and it’s one of the most common Inner West jobs. The house is supported to the engineer’s underpinning design, the ground under it is dug in stages through the front or rear, and rock is sawn at the party walls so the neighbours’ footings stay put. Spoil goes out by conveyor.

Through the house on boards with the floor protected, or over the back fence by crane. Spoil comes out the same way or by conveyor into a skip in the lane. Slower than a side gate and priced for it, but it’s how most Inner West yards get dug.

Along the rivers, Parramatta Road and the old industrial land, possibly. A century of fill is common and some of it carries lead, ash and asbestos. Council maps flag it, spoil is classified and managed to a plan, and the site look prices the handling honestly.

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.
