With more than 30 years’ experience, Diona provides a comprehensive ‘one-stop’ service offering, covering all aspects of design and construction encompassing trenching, drilling and pipeline installation for water, drainage, sewer, gas and electricity infrastructure. Diona’s team of over 500 employees operates in New South Wales, Queensland, Victoria and South Australia.

Specialising in the delivery of challenging and complex projects, Diona embraces these challenges and that is what drives them to be innovative in both design and delivery.

Diona believe there is always a more cost-effective, time-saving, safer, and technically robust way of delivering a project – and make it their goal to find it. Diona’s outside-the-box thinking and tenacious culture is something they pride themselves on and use it to design solutions that both work for the here and now and years to come.

“Diona is committed to continual improvement and ISCA provides a wealth of resources to promote and accomplish this through education, training, and networks of suppliers of sustainable products and services.”
