Mobilisation & demobilisation
Low-loader in with the jaw and the screen, set up on your pad, and the same trip back out at the end. One charge for the campaign, not per machine.

Mobile crushing & screening
Padstone CrushingWe bring the crusher to your pad — Kwinana, Perth metro and down to Bunbury.
The slab, the footings and the brick you just knocked down are road base and drainage aggregate. We crush and screen them where they lie, so you stop paying to cart rubble out and product back in.

On — cart on site, sprays on the jaw and the screen
A crusher on a suburban block runs behind a water cart. That’s not an upsell, it’s the condition we work under.
What it costs
Six numbers, and none of them move once we’ve seen the pile.
Crushing is priced by the tonne and the tonne is the pile’s volume times its density — so the only argument on a Padstone job is how many cubic metres are actually there. We settle that on the first morning with a machine and a tape, not on the invoice.
Crushing & screening — concrete
Slab, footings, panel and kerb. Reo comes out over the magnet. Screened to MRWA Specification 501 grading when you want it as road base.
$16.50 per tonne$9,800 minimum campaignBrick, masonry & mixed demolition
The messy end of a knockdown — brick, render, tile, a bit of everything. Softer than concrete, so it goes through faster and it costs less a tonne.
$14.00 per tonnemixed demolition, same rateLimestone & rock
Site limestone, granite floaters, capping off a subdivision. Hard on liners and jaw plates, slower through the chamber, and it always runs behind water.

If your machine is booked elsewhere, ours sits on the hopper all day and keeps the jaw choke-fed. Choke-fed is what makes the grading consistent.

The paperwork
What has to be in place before a jaw runs on your block.
Crushing since 2015Eleven seasons of demolition pads, subdivision limestone and civil stockpiles between Midland and Bunbury.
One 40-tonne mobile jaw, one two-deck screenWe run our own plant. You get the same operator and the same machine for the whole campaign, not whatever the hire yard had free.
DWER works approval & a dust planWorks approval under the Environmental Protection Act 1986 (WA), reference DWER-0000 (placeholder), and a written dust management plan lodged for every suburban job.
Screened to MRWA Specification 501Recycled road base is graded and tested against Main Roads WA Specification 501. A grading result goes out with every campaign.

Sites we’ve been on
Three jobs, told the way the contractor told them.
“Twelve hundred cube of slab and I had a cartage quote that made my eyes water. Padstone were on the block for three days and none of it left. I stockpiled the road base in the corner and used it under the new hardstand.”
Demolition contractor · Bayswater
“We had a rock stockpile sitting in the yard for two years doing nothing. They set up on a Monday, and by Thursday I’d bought my own rock back as base at about a third of what the quarry wanted delivered.”
Civil contractor · Kwinana
“The shire had already had two calls about dust before the crusher even turned up. The cart came with it, the sprays ran all day, and I didn’t hear another word for the rest of the fortnight.”

Written as demonstration copy for this build — Padstone Crushing is a fictional business and these are not real customers.
Where we go
Kwinana out, and down the freeway as far as Bunbury.
The plant floats on a low-loader, so distance is a movement charge, not a rate change. Metro is in the price. Peel and the south-west carry a float. Past that we quote the trip properly rather than guess it.
In the metro price: Kwinana, Rockingham, Baldivis, Canning Vale, Bayswater, Midland, Armadale, Wattleup, Henderson and everything between the coast and the hills. On the float: Mandurah, Pinjarra, Waroona, Harvey, Australind and Bunbury. Past Bunbury or east of the scarp, ring us and we’ll price the trip on its own.

You don’t need a survey. A rough cube figure and a photo of the pile is enough to get within ten per cent, and we confirm it with a machine on the first morning.
Straight answers
Six things every contractor asks before the first job.
What does crushing on site actually save me?
Two cartage bills and a levy. You stop paying a truck to take rubble off the block, you stop paying a second truck to bring aggregate back on, and whatever you don’t send to landfill doesn’t attract the landfill levy under the Waste Avoidance and Resource Recovery Levy Act 2007 (WA).
We will not put a dollar figure on the levy saving anywhere on this page. It depends on your tip, your material classification and what your dockets actually say — so it’s your weighbridge dockets, not our number. What we will quote is the crushing.
How much product comes out of a slab?
Concrete runs about 1.6 tonnes to the loose cubic metre, so a 1,000 m³ slab pile is roughly 1,600 tonnes of feed. Brick and mixed demolition are lighter — 1.35 and 1.5 — and site limestone is heavier at 1.75.
What comes off the belts depends on the screen apertures. On the road base setting a concrete job splits roughly 72 per cent minus-20, 20 per cent 20–40, and 8 per cent oversize that goes back through the jaw. The Deck at the top of this page runs those numbers live.
What will the neighbours hear, and what does the dust plan do?
A jaw on a suburban block is loud — there is no version of this that is quiet. We work inside the shire’s noise conditions, normally 7am to 5pm weekdays, and we tell you before we start how many days it will be so you can letterbox the street.
The dust plan is water. A cart on site, sprays on the jaw and on the screen discharge, and the stockpiles damped down at the end of the day. On a suburban block the cart is not optional — it’s the condition we work under, and it’s the same on limestone anywhere.
What are the products actually good for — and what aren’t they?
Minus-20 recycled concrete makes good road base and hardstand and can be screened to MRWA Specification 501 grading. The 20–40 fraction is drainage aggregate — soakwell surrounds, French drains, behind retaining walls. Oversize is fill, or it goes back through the jaw.
They are not structural concrete aggregate, they are not bedding sand, and recycled brick is not road base — it’s fill and it behaves like fill. If a spec calls for virgin quarry product, buy virgin quarry product.
How long does a campaign take and what do you need on the pad?
We work on a 6.5-hour crushing day once fuel, blockages and moving the excavator are in the figure. Mixed demolition runs about 845 tonnes a day, concrete about 780, brick 910 and limestone 617 — so a 1,200 m³ mixed pile is three days.
On the pad we need a level working area about 40 metres by 25, room for three stockpiles that won’t be driven through, a water source or somewhere for the cart to fill, and the pile within reach of the hopper. If your machine feeds us, it needs to be there all day.
What do you not do?
We don’t demolish. We don’t cart — no trucks, no tip runs, no deliveries. And we don’t certify your pavement design: we can give you a grading result against Specification 501, but the decision to put our product under your pavement is your engineer’s, not ours.
We also don’t touch asbestos-contaminated material. If there’s bonded fibro through the pile it has to be picked out and disposed of properly before a jaw goes anywhere near it.
