What is Composite Decking?

Composite decking is manufactured using a combination of recycled plastics, reclaimed wood fibres like sawdust or wood chips, plus a safe binding agent. Some companies also use sustainably grown timbers, like bamboo. Over the years, manufacturers of composite decking have prevented millions of tonnes of plastic from going to landfill.  

The composite decks we see today can mimic the grains and colours of traditional timber so well it can be hard to point out which is composite and which is real timber. Aside from the aesthetic appeal, there are many other benefits that make composite a popular alternative to timber decking, these include:

  • Easy installation
  • Eco Friendly
  • Resistant to termites
  • Low maintenance

Since composite decking was first introduced in the 1990s, manufacturers have taken on the challenge to evolve the product. Innovations like UV protection, click and lock installation, non-slip and cool surface technology have created a multitude of uses for composite decking.

Austim’s range of composite products will give you the look and feel of timber decking, without the ongoing maintenance.

Technical Specifications

  • Low Maintenance
    Compared to traditional timber, composite decking is very easy to clean and maintain. Not only is it very durable, being able to withstand tough conditions, but the only maintenance it needs is regular cleaning with soapy water – oiling is not required.
  • Modern design
    Our timber decking alternatives take on the appearance of a wide range of wood styles so you can customise your decking to suit the design of your outdoor space.
  • Less expensive
    Composite is less expensive over the lifespan when compared with traditional timber.
  • Built to last
    We are so confident that our decks will last and won’t fade, that we guarantee it with performance warranties ranging from 10 to 25 years.
  • Safe
    Does not split or splinter, making it a solid option for bare feet. Many options are also water tolerant and slip-resistant and are perfect to use around a home pool or spa.
  • Eco-friendly
    95% of the materials used to produce composite are either recycled plastic or reclaimed wood. By choosing composite decking, you are preventing hundreds of thousands of tons of waste from entering landfills each year.
  • Easy to install
    Boards are manufactured with a groove system with special fixings, making installation a very easy process. No nails are required to install it and most people find installation much easier than timber decking installation.
  • Durable
    Composite timber is designed to stand up to Australia’s harsh conditions. It handles heat, UV exposure, rain, moisture, and pests without staining, fading, or scratching.


Several brands have created composite decking boards with fire-retardant additives. ModWood Flame Shield can be in areas with a fire rating of BAL-12 to BAL-40.

Composite decking comes in a range of different surfaces. Many brands like Eva-Last and Millboard manufacture composite boards that are slip resistant even in wet conditions. When using composite decking around a pool, ask your supplier about the anti-slip rating. 

This purchase cost of composite decking can be higher than most timber decking alternatives. However, installation and long-term maintenance is substantially less. Composite decking never needs to be sanded, oiled or sealed and will not rot, warp or attract termites like some timbers. It’s important to look at the long-term savings of composite decking.

One of the main benefits of composite decking is that it’s low maintenance. Once installed you never need to paint or stain your deck to keep it looking great. However, if you’re considering changing the colour of your composite decking it’s not recommended that you paint or stain it.

If you have a concrete backyard or front porch you want to modernise – you can install composite decking over the top (with a few conditions). First, the concrete area should be completely flat. Also, if the area is exposed to rain, you’ll need to allow the water to effectively drain. By creating a subframe, you can raise the composite decking slightly off the ground and prevent any water pooling.

As the name suggests, composite decking is a mixture of products. The primary components include recycled plastics and reclaimed wood products. The wood used can range from sawdust to wood chips to sustainably-grown bamboo. The type of recycled plastic used will depend on the product you order. Some plastics have a higher melting point and will absorb less heat – helping the deck stay cooler.

There are so many benefits to installing composite decking. Apart from it looking great, it’s extremely low maintenance – an occasional sweep is all it needs to stay looking new. While there is a range of composite decking products available, the majority are stain and scratch resistant. Longevity and long-term savings are also key benefits. Most composite decking is backed up with a 25 – 30 year warranty, however, you can safely assume your decking will last a lot longer than that. 

Each manufacturer has their range of colours, however, many have created a range that looks just like traditional timber. The colour and grain often look identical. If you’re looking to match the composite decking with your current decor, you’re likely to find a match.
