Excavation & Earthworks Guildford West

It depends on the volume of material, the ground (shale clay on flat ground), 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.

Rarely. Shale clay on flat ground, low toward Prospect Creek. Shale under the clay is ripped rather than broken. Real rock work in this region is along the river and at Prospect, not on the flat streets.

Cumberland is one of the easier councils for it, and the 50s and 60s blocks have the room. The pad is cut through the side access, compacted, and trenched for services at the same time.

Reactive clay. It swells in wet winters and shrinks in dry summers, and anything poured on loose or uncompacted fill moves with it. A pad cut and filled in compacted layers to the engineer’s spec is what stops the new slab doing the same thing.

Yes, and it changes the job. A flood planning level sets the floor height, which can mean filling up rather than cutting down, with the fill placed in layers and certified, or it can restrict fill altogether. The site look and your approved plans decide it before the quote.

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.
