Whole of Structure
Austral Deck

Austral Deck is a permanent formwork and precast decking solution. The Austral Deck flooring solution can easily accommodate varied designs, shapes, thicknesses, penetrations and cast-in fittings.


Austral Deck is a flexible solution designed to be installed with the entire range of Austral Precast Walling, Framework, and Balcony solutions, offering a complete precast building solution.

The permanent formwork is an ideal and economic solution for constructing concrete floors for single or multi level structures, concrete decks and platforms.


As a revolutionary permanent formwork, the Austral Deck solution combines precast concrete panels with a cast in-situ topping to create a suspended concrete slab. Austral Deck is a exible solution designed to be installed with the entire range of Austral Precast Walling, Framework, Stairs and Balcony Solutions offering a complete precast building solution.

Austral Deck incorporates triangular truss reinforcement (lattice girder) providing a bond between the precast and in-situ concrete. These trusses increase spans between temporary props during construction and contribute to the reinforcement mass of the final slab.

Austral Deck is a factory made precast panel that can be designed and manufactured to suit a variety of building functions and occupancies, catering for a range of imposed and permanent loads. Lengths of panels are generally limited to 12m and its standard width is 2.5m for handling and transport purposes. Austral Deck comes in a standard thicknesses of 70mm to suit various slab design specifications.

Austral Deck is an ideal and economic solution to construct concrete floors for single or multi level structures.

Features and Benefits

Austral Deck is easy to design with and fast to install, saving time and money across the
construction life cycle. A flexible and adaptable formwork, Austral Deck integrates well with
Austral Precast walling solutions, covering the entire structure including cantilevers and

A Unique Flooring Solution

  • An Austral Deck panel is part of a composite floor system that provides rigid formwork and becomes part of the final structure. During construction the panel can stand construction loads and be used as a platform for workers and materials.
  • An effective way to maintain the structural integrity of a monolithic slab.
  • Composite platforms and shear connection panels can be constructed easily with partial or full-length gaps or pockets of concrete block-outs. The gaps will be located to accommodate structural beam configurations. This allows for the placement of the Austral Deck directly over precast, cast in-situ concrete or steel beams. Trusses and steel reinforcement can remain uninterrupted through these gaps for structural continuity.
  • The permanent formwork system has been approved by many state road authorities, providing safer and more efficient construction of bridge superstructures.
  • The high quality off form Class 2 finish on the under side of the Austral Deck floor eliminates to gyprock or plaster the ceiling.

A Flexible and Adaptable
Formwork Replacement

  • Austral Deck imposes minimum restrictions on designers and builders. Custom made sizes and shapes can be manufactured to suit construction layout and design specifications.
  • Austral Deck panels can cover the entire width of a structure, including the cantilever beyond the external support.
  • The system integrates well with concrete or steel framed structures and within the entire Austral Precast product offering.
  • Cast-in items such as ferrules, conduits and other service fixings and penetrations can be accommodated during the manufacture of
    Austral Deck.
  • Balconies and edge forms can be cast within the Austral Deck panel. These can eliminate edge formwork and scaffold costs. Integrated edge forms allows for early installation of temporary or permanent balustrades.
  • Safety rails can be prefitted to the panels prior to installation, improving site safety.

Economic And Fast To Install

  • Reduction in formwork and propping compared to conventional formwork.
  • To further increase efficiency on site, Austral Deck panels may be produced with void former blocks attached to the top of the precast. These formers reduce the volume of in-situ concrete topping volumes and reduces the overall mass of the floor structure typically by 30%.
  • Construction trades can commence working on the structure immediately after installation. Services ducts and conduits can be installed and accommodated into the cast in-situ portion of the slab.
  • Panels can be lifted straight into position, reducing conventional installation time. An average 10 panels (covering an area of 150m2) can be installed hourly. The panels have a relatively thin layer of concrete, which makes it lighter to transport and install.
  • The excellent fire, thermal and acoustic advantages of Austral Deck are superior to other light weight flooring options.
  • Off form Class 2 finish is easily achieved, no extra work is required on the Austral Deck soffit.


The permanent formwork is an ideal and economic solution for constructing concrete floors for single or multi level structures, concrete decks and platforms and to construct roofs and lids.

Austral Deck Post Tensioned

The flexibility of Austral Deck means it is well suited to accomodate slab post tensioning components.

For residential applications spanning 10m, it is reccommended that post tensioning is employed. The combined precast post tensioned solution offers many advantages compared to cast in situ post tensioned solutions including; reduction in concrete volume, post tensioning amount and rate.
