Bigger jobs, same standard

Coastwide Earthworx started with tight residential work and has grown into larger projects. The machines are bigger, but the way we work has not changed: we turn up when we say we will, work to the drawings, and communicate early when the ground does not match the plan.

A maintained fleet

We run current-model machinery with full service history, maintained to a high standard. On a commercial program, a machine that does not break down is worth more than a cheap hourly rate.

Working inside your program

Tell us the project dates and the trades that follow us. We will plan the earthworks so pads, trenches and access are ready when the next crew needs them.

What size projects do you take on?

Commercial projects of all sizes. Send us the drawings and the scope and we will tell you honestly whether it suits our fleet.

Can you work to a head contractor’s program?

Yes. We are used to fitting earthworks around other trades and inspections.

Do you remove material from site?

Yes. Spoil and demolition material can be removed as part of the job.

Do you do rock breaking?

Yes. Rock breaking and concrete removal are part of our commercial and residential work.
