What is Composite Decking?

Composite decking is a popular alternative to traditional wood decking and closely mimics the look and grain of real wood without high maintenance. It feels smooth to the touch and keeps its good looks with minimal upkeep. This decking is made from a blend of wood fibres and recycled plastics or uPVC, combining durability with a low-maintenance surface and making it a favourite among many homeowners.

Composite Decking vs. Wood Decking

Wondering whether to choose composite decking over natural timber? Here are the key benefits:

• Low-Maintenance: Traditional wood decks need regular sanding and refinishing, but composite decking only requires an occasional pressure wash.
• Aesthetic Appeal: Composite decking can match the beauty of wood decking and doesn’t fade as quickly.
• Durability: Made from plastic and wood pulp, composite decks are strong, although they generally don’t last as long as harder woods like Tallowwood or Ironbark.
• Resistance: It’s scratch, stain, and mould-resistant due to its manufacturing process. Although susceptible to some staining from oils, it’s generally robust against common deck wear and tear.
• Water and Fire Resistance: Most composite decks are completely water-resistant, making them ideal near pools or in gardens, and many options are fire-resistant, suitable for bushfire-prone areas.

Composite decking is also eco-friendly, often made from recycled materials, which reduces the need for virgin plastics and logging.

In South Africa, popular composite decking suppliers include The Composite Company, Eva-Last, Best Deck, Envirodeck, On The Deck, and 4Everdeck.

Main Differences Between Composite Decking Products:

• Capped Composite Decking: This type features an additional protective layer made during manufacturing, enhancing stain resistance and durability, though it tends to be pricier.
• Attachment: Composite boards can be drilled and screwed like traditional wood, but more sophisticated options might include hidden fasteners for a cleaner look.
• Finish: High-end composite decking boasts more detailed grain and color patterns, offering a closer resemblance to real wood.
• Scalloping: Some boards have scalloped or hollowed-out bottoms to reduce costs, which may impact durability.
• Waterproofing and Fireproofing: Decking that is fully water- and fire-resistant generally comes at a premium, depending on the brand.

These suppliers provide a variety of options that cater to different styles, budgets, and project requirements across South Africa.

How Much Does Composite Decking Cost?

Several factors influence the total cost of your decking project:

• Materials: Composite decking tends to be pricier than hardwood. Higher-end brands offer more realistic wood grain textures and a broader colour selection. Hidden fasteners, which create a seamless deck surface, also add to the cost.
• Size: The size of the area you want to deck is a major determinant of cost. Installers usually provide a complete quote including materials and labour.
• Permits and Approvals: Costs for necessary permits, if required, are usually paid to your local municipality.
• Design: Complex designs may require sign-off by a qualified professional to ensure safety and compliance with local building codes, which include specific construction standards.
