Duggans Pty Ltd is a 100% Tasmanian family owned company that has been operating in the Huon Valley for over 85 years. Our Cradoc site comprises a quarry, precast concrete factory, premix concrete batching plant, plant workshop, earthworks/civil yard, welding shop and office.

From the supply of quality products from our onsite quarry, and the supply of premix concrete from our onsite batching plant , to the manufacture and delivery of precast concrete panels along with the years of experience from our professional civil and earthworks team.

Duggans can provide you with what you need to complete your own projects or work hands on with you to see the job through to the end.

We are currently in the process of creating Duggans Integrated Management System. Once complete the system will incorporate Duggans Environment, Quality and WHS Management systems to ensure as far as practicable quality products, safe and healthy employees and sub-contractors and a clean and safe environment for the local community, meaning professional service for our customers.

Successfully producing its own quality controlled crushed dolerite aggregates and road bases, the quarry is our hub of operations.

It supplies the Huon and Channel areas with a full range of quarry gravels and road base materials along with externally sourced products, such as agricultural lime and dolomite, topsoil, gum chips and specialty sands.

Along with direct customer supply, the quarry also feeds our Premix Batching Plant with aggregates for the manufacture of top grade premix concrete. Our batching plant supplies quality premix concrete directly to our builders, contractors and private customers, and our five truck fleet service ensures product availability.

Duggans premix concrete is also used in our precast concrete factory, where we manufacture and deliver precast concrete panels and components for the building industry and private sector state wide. We have our own drafting office and have been manufacturing high quality precast concrete and delivering it to sites throughout Tasmania for over 25 years.

Also drawing from our quarry is our civil and earthworks department, using materials such as the gravels, drainage rocks, pipe bedding, shoulder materials and sub-base and base courses for projects both large and small. With a growing range of plant and equipment, our skilled experienced operators and professional earthworks team will work with you to fully develop and deliver your project, whether it be a dam, driveway, a house site or a fully serviced development or subdivision.

Working under the one strategic plan Duggans Quarry, Batching Plant, Precast Factory and Civil/Earthworks Department, with the support from the Workshop and Administration aim to provide our customers superior quality products and a complete and unique service.
