Doing the right thing for our people, our clients and the environment — on every site, every day.

Health, safety & environment

Doing right by our people and the planet

Safety and sustainability aren't add-ons at DIS — they're built into the way we inspect, report and work on every site.

Health & Safety First

Safety is fundamental to the way we work. Our health and safety systems support consistent, well-managed operations, minimise site risks, and protect both people and underground assets.

Safer, more productive sites

Our technological advancements enable us to deliver both enhanced productivity and safer working practices.

Recycling & reuse

Improving clients' sustainability performance through recycling of liquid clean fill into non-potable water and constituent aggregates.

Because it's the right thing to do

We do right by the environment and the communities we work in — our company values on every job.
