Deck Pedestals

Decking pedestals and supports in New Zealand are characterised by their height, slope correction, load, and material. The range also includes pedestal deck system options for timber, composite and tile finishes. Some floating deck systems use pedestals to support the framing above the substrate, allowing the deck height to be set independently of the underlying surface.

Not all terrace decks have the same height requirements. Therefore, manufacturers developed pedestals with adjustable heights. Their height typically varies between 11mm and 1,130mm. A deck cradle is an adjustable support beneath raised deck framing, with its height set to suit the required clearance.

Pedestals can also be used on inclined terraces and roofs. Most deck pedestals in New Zealand come with a slope correction percentage between 5% and 15%.

Pedestals also vary according to the maximum weight they can support. The average weight supported by a pedestal varies between 100 and 1,000 kilograms.

They are available in several types of plastic as well as concrete stumps. Some manufacturers also offer pedestals made with recycled materials that can also be reused.

Some pedestals feature holes that allow professionals to screw them to the substrate underneath. This helps create additional support, increasing its resistance.

High-quality deck pedestals are incredibly versatile and can be installed with any structural deck substrate material, including wood, concrete, plywood, and more. They can also support a wide range of flooring or decking structures, such as stone tiles, vinyl, or waterproofing membranes. High-quality options are precisely designed and engineered to ensure your deck remains safe, even under heavier loads. They are made with superior-grade materials that will also last longer, saving you money on maintenance and repairs. Given how important they are to the safe use and integrity of any deck, they are not something you want to take a chance on with respect to quality, so you should always insist on the best of the best. For tiled areas, a deck tile pedestal system can provide adjustable support over the substrate.

The main factor that influences your choice of deck pedestals is your project’s specifications. If your terrace has a higher angle, you should choose an adjustable decking support with a higher slope correction percentage. The desired height is also extremely important. If you have wiring or tubes underneath your deck, choose pedestals with a higher height limit, as it gives you more space to work with. Last but not least, consider the load. Opt for heavy-duty pedestals for higher-traffic areas, such as those in commercial buildings or shared decks.
