About Deck Foundation Accessories products

Deck foundation accessories address different parts of a deck build, from board joints to the supporting frame. These deck accessories include the ShadowDeck™ 80mm Butt-Joint Double Screw Fastener and the BiForm JOIST MOUNT SYSTEM. Check each product’s stated application against the decking design and the detail being resolved.

Deck Foundation Accessories

For a floating surface, the category includes Anchorjak™ Floating Tile Platforms and ShadowDeck | Floating Deck Framing System. On a New Zealand site, a section drawing can help establish the space between the substrate and finished deck level, particularly at a door threshold. Compare that available height with the product requirements before setting out the foundation.

How should drainage be handled beneath a floating deck?

Keep outlets clear and make sure the finished layout does not block water flow. Allow for access to drainage points that may need maintenance.

Can a floating platform be used on an uneven surface?

Check the product information for the substrate requirements and any adjustment range. Do not assume a platform will compensate for a change in level.

What should be included in the installation information?

Give the installer the selected product details, deck layout and finished level. Include the relevant technical instructions for the support and board-fixing details.
