The Lighthouse, a 1:1 scale 1950s family home situated in the heart of Auckland’s downtown, features a light display inside as well as a sculpture of Captain Cook, titled The English Channel. The installation was erected on Auckland’s Queens Wharf in 2019 and required a high-performance timber deck to enclose the exterior of the building and accommodate the thousands of visitors to the site each year.
Dominion Construction opted to use the ProFoot Adjustable Deck Pedestal System from Marshall Innovations, providing a cost-effective and extremely durable finish to the existing uneven concrete surface. ProFoot is a fully-adjustable deck pedestal system designed to be flexible for use in even the toughest situations.
ProFoot was the perfect choice in this situation (comprised of mostly flat deck with integral access ramp), with 250 x 50mm timber joists providing plenty of rigidity and support for foot traffic on timber decking above. The ProFoot L-Adaptor allows for secure fixing and attachment of the timber joists to the pedestal and is easily clicked into the pedestal head.
The particularly uneven concrete substrate surface beneath added to the challenge of building a flat and level deck, however, the TradeWedge 10 was used in addition to the ProFoot pedestal to provide ‘versatile slope adjustment’, adding the necessary system flexibility to counteract this.
The deck height from the concrete slab was significantly increased in some parts of the deck, and so it was necessary to set pedestals at varying heights and to also include 100mm Extension Rings in areas as required. These are easily clicked into the pedestal base, and greatly assist in maintaining a level timber deck.
No pre-treatment work was required of the concrete slab surface beneath this deck, which meant a quick start to the deck construction process and this concrete remains purposefully in-place to provide solid foundations for a stable deck system for many years to follow.
