What Bankstown and Canterbury jobs need

Duplex country on clay, with a river at each end

Digging in Bass Hill is duplex country on reactive clay, with a river at each end. The 50s and 60s brick veneer is being split and backed with second dwellings street by street, and every pad goes onto clay that cracked the old slab; the Cooks River and Salt Pan Creek flats flood, and the Georges River blocks drop toward the water on sandstone. So the job is clay and compaction on the flat, flood levels on the creek flats, and rock and benching on the river slopes, with services located on streets that were never fully mapped.

What's different about digging in Bass Hill

Bass Hill, in short

Bass Hill sits about 22 kilometres south-west of the city. You'll recognise it by Bass Hill Plaza, Hume Highway and Georges River nearby. It's ringed by Chester Hill, Sefton, Georges Hall, Condell Park and Villawood. What's changing: knock-down rebuilds, granny flats and dual-occupancy, and pools and townhouses on the older lots.

The houses, and what they need

Bass Hill's housing near Bass Hill Plaza runs to federation and post-war brick homes with granny flats and knock-down rebuilds. Near Bass Hill Plaza, duplex and unit sites cluster near the centres. Day to day around Chester Hill that's pool digs, site cuts and knock-down rebuild site cuts.

The ground under Bass Hill

On the Cumberland Plain, Bass Hill ground runs to Wianamatta shale over reactive clay, near Bass Hill Plaza. Being flat by Hume Highway, a Bass Hill block needs the fall cut into the pad and the trenches, since it won't drain on its own. Around Sefton, the clay is reactive, so fill goes in in compacted layers.

The council, access, and getting to you

Bass Hill is City of Canterbury-Bankstown ground; with nothing flagged around Bass Hill Plaza, the dig sits under the DA or CDC. The Bass Hill crew comes in off Chapel Road or Waldron Road.

Excavation in Bass Hill, answered

How much does excavation cost in Bass Hill?

It depends on the volume of material, the ground (wianamatta shale over reactive clay on the cumberland plain), 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.

Do I need council approval before you dig in Bass Hill?

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.

How long does an excavation job take in Bass Hill?

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.

Is there rock in Bass Hill?

Rarely on the flat streets. Wianamatta shale over reactive clay on the Cumberland Plain. Shale under the clay is ripped rather than broken. The rock in this region is on the Georges River side, not around Bankstown and Canterbury centres.

Do you do duplex site cuts in Bass Hill?

Yes, and Canterbury-Bankstown is the busiest duplex market in Sydney. The old house down, slab and footings out, the block stripped, and two pads cut and compacted to the engineer’s spec, with the shared driveway boxed out at the same time.

Is Bass Hill good for a granny flat?

It’s one of the easiest councils for it, and the 50s and 60s blocks have the room. A mini excavator through the side access, the pad cut level and compacted on the clay, and the service trenches run at the same time.

Why do slabs and driveways crack around Bass Hill?

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.

Do you do knock-down rebuild site cuts in Bass Hill?

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.
