A third generation family business, we value our employees and our customers and we pride ourselves in maintaining strong and lasting relationships with both. In building these relationships the business has grown from a transport business in 1927 to a business that can provide all components and expertise for a successful project.

We are a wholly family owned company operating from Cradoc in the Huon Valley.

Future Driven, Backed by History

Our founder, Harry Duggan, started business in 1927 when he purchased his first truck. Today Duggans is Tasmania’s leader in the manufacture and supply of precast concrete.


In the late 70s Duggans acquired a concrete batch plant and commenced supplying the local market with quality premixed concrete. Concrete aggregates at this time were purchased from quarries located in Hobart. Because of the long haul from Hobart to Cradoc over the narrow and windy Huon Road, we extended our existing quarry to include the production of quality concrete aggregates.


Many major road projects, constructed by both government departments and private contractors, have been supplied by Duggans Quarry Division from the quarry, as well as our premix concrete plant and the specialist crushing of imported aggregates for exposed aggregate concrete.
