Road Construction

Road construction and maintenance has been our core business for over 20 years. We have an experienced team of skilled operators and ground staff who work on a wide variety of projects, ranging from small subdivisions to major highway construction. This work involves elements of all services provided by AWC including:

  • road rehabilitation
  • earthworks
  • underground services
  • concrete structures
  • pavements
  • shoulders and verges
  • drainage



Subdivision constructions are a large part of our business. We have a long and successful track record in constructing residential, rural and industrial subdivisions. These range in size from single lot subdivisions to multi stage developments and involve elements of all the services we provide (including road construction, earthworks, underground services and concrete structures).

Road Rehabilitation

AWC is the only company in Tasmania with a continuous presence that can offer road rehabilitation through the stabilisation or modification of subgrades and pavement gravels using our Caterpillar RM300s – the only two reclaimers based in Tasmania.

The reclaiming process is a method of repaving roads which is more environmentally efficient and provides a cost saving to the client. It works by taking unsuitable pavement material and introducing additional material, such as cement, lime, gravels, blended cements, bitumen or other chemicals, to improve the grading or physical properties of the original material. The end product is a quality, environmentally efficient material that is significantly improved from the original material. This service has become much sought after, particularly by local municipalities.

Our road rehabilitation services include:

  • lime stabilisation
  • cement stabilisation
  • granular stabilisation
  • reclamation/milling of existing pavements.

Underground Services

AWC has a long and successful track record with the construction of underground services. These projects have seen the successful construction of small and large diameter heavy industrial pipelines with major pump stations and river intakes and discharges. We have skilled and knowledgeable teams that have delivered sewer, stormwater, waste and recycled water projects to local and State Government, Australian and Water Authority Standards.

AWC has also worked with service authorities in the installation of:

  • sewer, water and stormwater
  • pump stations
  • power and communication

Dam Construction

AWC has experienced teams who have been involved in dam construction projects of all sizes and complexities, from small farm dams to raising tailings dams to multi-million dollar dam filter upgrades. Some of these projects have been remote and undertaken in difficult weather conditions.

Recent projects have included the construction of recycled water dams for water authorities and dam liners for storage of industrial waste. AWC has also been involved in the maintenance cleaning of Hydro Tasmania’s canals for over 10 years.

We can provide crushing and screening services on-site for large projects, with customers able to reuse the end product in their project.

Our crushing and screening services include:

  • recycling of demolition concrete, including heavily reinforced concrete
  • cartage of demolition concrete from project sites
