Material Precast concrete

Precast concrete offers durable, flexible solutions for floors, walls and even roofs in every type of domestic construction from individual cottages to multi-storey apartments. Concrete’s high initial embodied energy can be offset by its extended life cycle (up to 100 years) and high potential for reuse and relocation

The advantages of precast concrete include:
  • Speed of construction reliable supply — made in purpose-built factories and not weather affected
  • High level performance in thermal comfort, durability, acoustic separation, and resistance to fire and flood
  • Inherent strength and structural capacity able to meet engineering design standards for housing ranging from individual cottages to multi-storey apartments
  • Highly flexible in form, shape and available finishes ability to incorporate services such as electrical and plumbing in precast elements
  • High structural efficiency, low wastage rates on site
  • Minimal waste, as most waste in the factory is recycled
  • safer sites from less clutter
  • Ability to incorporate waste materials such as fly ash
  • High thermal mass, providing energy cost saving benefits
  • Simply designed for deconstruction, reuse or recycling.
Precast concrete does have disadvantages:
  • Each panel variation (especially openings, bracing
    inserts and lifting inserts) calls for complex,
    specialised engineering design.
  • It is often more expensive than alternatives (can be offset by reduced construction times, earlier access by following trades, and simplified finishing and services installation).
  • Building services (power, water and gas outlets; conduits and pipes) must be accurately cast in and are difficult to add or alter later. This requires detailed planning and layout at design stage when plumbing and electrical trades are not usually involved.
  • Erection requires specialised equipment and trades.
  • applied finishes such as etching, grit-blasting, honing, polishing and exposed aggregate (off-site only where highly alkaline wash-down water and sediment can be recycled to avoid pollution of waterways).
Appearance

An almost endless variety of shapes, colours, textures and finishes is available for precast concrete. It can be moulded and shaped to suit almost any design or form. Simple surface treatments are:
• rebating and grooving
• surface coatings
• cement-based renders.

Other more complex treatments can also be used, such as:
• form liners
• oxide colouring
• applied finishes such as etching, grit-blasting, honing, polishing and exposed aggregate (off-site only where highly alkaline wash-down water and sediment can be recycled to avoid pollution of waterways).

Structural capacity

Structural precast concrete panels are a strong, durable and versatile building material, particularly suited to Australia’s harsh climatic extremes and requiring minimal maintenance. They can be engineered to meet the structural needs of every type of domestic
construction. Concrete is flood and fire resistant and doesn’t shrink, rot or distort. It gains strength as it ages and in structural terms is ideally suited to the unpredictable conditions associated with climate change. The inherent structural properties of precast walls mean that they do not require additional bracing to resist racking loads and that simple design of cross walls and junctions can provide adequate lateral bracing. Tie-down inserts to resist cyclonic winds are simple to design, install and connect. Precast finishes are highly impact resistant, withstand wear and tear, and require minimal repairs and maintenance.
