Excavation & Earthworks Dee Why

It depends on the volume of material, the ground (coastal sand over hawkesbury sandstone near the beach and lagoon flats), 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 flats. Coastal sand over Hawkesbury sandstone near the beach and lagoon flats. Behind the beaches it’s sand over lagoon silt, and the problem is water rather than rock: the dig is shored and dewatered instead of sawn and broken.

Yes, and it’s the standard flats pool. Sand walls don’t stand, so the dig is shored or battered, the water table is pumped from a sump, and the shell goes in fast once the hole’s at level. The pool builder’s engineer usually wants the base checked for silt.

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. One house down, the block stripped, and two pads cut and compacted to the engineer’s spec, with the basement dug if the design has one.

Yes. Small machines go through the house or over the fence by crane, and spoil comes out by conveyor or barrow. Slower than a side-gate job, but it’s how most inner-suburb digs are done.
