Crushing and screening for civil construction
Make compactable base and sub-base from the rock and recycled concrete already on your site, so earthworks stay on program and you stop trucking spoil out and material in.
/ overview
On a civil job the cheapest base material is often the rock and concrete already under your feet. Crushing and screening on-site turns excavated rock, recycled concrete and site-won material into compactable base and sub-base, ready to place without waiting on quarry deliveries or paying to cart spoil away. That keeps earthworks moving on program: you make material to spec as you need it, reuse what you excavate, and cut the truck movements that slow a constrained site. A mobile crusher makes the product, and a screener grades it to the size your specification calls for.
Match the machine to the material. Hard, abrasive rock points to a jaw crusher for controlled primary reduction. Reinforced concrete, asphalt and mixed material point to an impactor for a cubical, well-graded product. A screener then cuts a defined base or sub-base off the stockpile, ready to compact.
It suits roadworks, subdivision and pad construction, drainage and pipeline trenching, and any earthworks program where the spec calls for graded fill and base.

Keep the program moving.
Make base to spec on-site
Produce compactable base and sub-base graded to your specification, when you need it, without quarry lead times holding up the next layer.
Reuse site-won material
Crush excavated rock and recycled concrete into fill and base instead of carting it out and trucking material back in. Less waste to dispose of, less stock to buy.
Fewer truck movements
Less cartage means lower haulage cost, less traffic on a constrained site, and fewer delays waiting on deliveries. The job is not tied to a supplier truck roster.

Buy
If crushing and screening is part of how you run earthworks, owning the machine costs less over time and it is always on site. We are Australia's leading dealer, so you buy factory-backed with local parts and support.
Hire
For a single project with a defined duration, hire the right unit for the job. We arrange the right machine for your site, operated or dry, with hire available Australia-wide.
/ questions
Common questions
Can I make road base on-site?
Yes. A mobile crusher reduces excavated rock or recycled concrete to a graded product, and a screener cuts it to your base or sub-base specification, ready to place and compact. You make spec material as the job needs it, without waiting on quarry deliveries.
Which is better for civil work, a jaw or an impact crusher?
Hard, abrasive rock points to a jaw crusher for controlled primary reduction to a set top size. Concrete, asphalt and mixed material point to an impactor for a cubical, well-graded product. If you process both, we will help you pick. See the crushers page for the full range.
Should I buy or hire for a civil project?
For a single job with a defined duration, hiring the right machine keeps it off your balance sheet and off your maintenance schedule. If crushing and screening is part of how you work across jobs, buying usually costs less over time. Hire is available Australia-wide.
Does crushing on-site really keep the job on program?
It removes two of the common hold-ups on earthworks: waiting on quarry deliveries of base material, and carting spoil off a constrained site. You make material to spec as the job needs it and reuse what you excavate, so the program is not tied to a supplier truck roster.
