Rock Crushing & Aggregate

Mobile and on-site crushing, screening and recycling — making the rock you need where you need it, instead of trucking it in.

Crushing where the rock already is

Hauling aggregate is expensive, and most of what you pay for is the truck, not the rock. When a project has material on site — native rock, an old concrete slab, a stripped asphalt surface, an existing pit — crushing it in place is usually the cheapest aggregate you will ever buy, and it takes truck traffic off the road at the same time.

We run mobile crushing and screening plants and move them to the job. We produce road base, drain rock, structural fill, riprap and spec aggregates, sized to what the project actually calls for.

Concrete and asphalt recycling

Demolition concrete and milled asphalt are aggregate that somebody already paid to make. We crush and screen them into reusable base and fill material on site. On a job with meaningful demolition, this frequently pays for a large part of the crushing mobilisation by itself.

Pit work and contract crushing

We do contract crushing for other contractors, for landowners with rock on their property, and for our own projects. If you have a pit and no plant, or a plant and no crew, that is a normal conversation for us.

Aggregate supply

Where a project needs delivered product rather than on-site production, our sister company Western Rock Products supplies rock and aggregate. Between the two companies we can quote crushed, delivered or produced on site, whichever comes out cheaper for you.

Common questions

Questions we get asked

What is mobile crushing and why would I want it?

It means bringing the crushing plant to your site instead of hauling material to a pit and product back. When there is enough material on site, it is normally cheaper than buying and trucking aggregate, and it removes a lot of truck traffic.

Can you crush the old concrete from our demolition?

Yes, and it is usually worth doing. Crushed concrete makes good base and structural fill, and reusing it avoids both the disposal cost and the cost of importing new rock.

How much material do I need before crushing on site makes sense?

There is no fixed number, because it depends on haul distance and what aggregate costs delivered to that location. Tell us the quantity and where the site is and we will tell you honestly whether crushing or buying is cheaper.

Do you sell aggregate as well as crush it?

Delivered rock and aggregate products come from our sister company, Western Rock Products. On-site crushing comes from us. We will quote whichever suits the project.

Do you do contract crushing for other contractors?

Yes. Contract crushing for other contractors and for landowners with their own rock is a regular part of what we do.
