Construction

For over 40 years, Diona has provided construction services for the delivery of essential utilities –water, sewerage, gas, electricity and telecommunications – to our towns and cities nationally.

We offer a complete turn-key solution, coordinating every facet of design through to construction to deliver all aspects of utility infrastructure.

Experience matters

Our teams have unsurpassed knowledge and have developed, over decades, strong working relationships with both private and public asset owners, utility providers, and local communities.

Our partnerships with government bodies and private owner clients translate to dealing with one contractor, delivering active community engagement, fewer unforeseen issues, and timely responsiveness to issues should they arise.

Whatever the challenge, Diona delivers.

We thrive on technically challenging, time-sensitive projects in difficult locations such as busy CBD streets, highly built-up residential divisions, or environmentally sensitive rivers and creeks.

Our ability to deliver some of the most complex scopes and against constantly changing weather and environmental conditions has seen us work on key projects for the likes of Sydney Water, Queensland Urban Utilities, Hunter Water and APA, to name a few.

In addition to conventional methods, bores, micro-tunnels and deep trenching, we are constantly evolving to ensure we remain ahead of the curve in our delivery techniques, making us a partner our clients can rely on to get it done right, every time. Our specially designed equipment, such as under-over rollers and twin rock saw cutters, are just some of the tools we use to maximise efficiency on site.
