Elevated Decks

Building perfectly level elevated decks

Building a roof deck on an existing building can often very challenging.
Firstly there’s the issue of constructing a foundation for your deck where in most circumstances the building owners will not permit any permanent structures to be installed on a rooftop.
Secondly, most building owners are particularly concerned that no damage will be done to any existing waterproof membranes which could result in costly repair work if any leaks were subsequently encountered.
Thirdly in many localities, and particularly in densely populated urban regions, fire regulations are becoming increasingly strict and in some localities prohibit the construction of a solid wood deck.
Fourthly, all decks will slope slightly for drainage, will no doubt have a series of service pipes, electrical conduits and other service ducts at least somewhere on the rooftop area, adding a further challenge to building a roof deck.

So the simplest solution of laying interlocking tiles over the existing waterproof membrane may not be the best way of building rooftop deck. Fortunately there’s a much better alternative.

A paver pedestal system where structural grade porcelain pavers are laid over pedestals can solve all the above challenging issues in building roof decks. With this system, 24” x 24” pavers are supported on each of the four corners only by pedestal supports which are adjusted up or down by screwing the central column. This enables a perfectly horizontal deck to be created which can successfully hide all service pipes and ductwork since the pedestals can be as high as 36” if required.  Porcelain pavers are completely fireproof, stain resistant, scratch resistant, frost proof and exceptionally low maintenance. Our Architrex porcelain pavers also come in an extremely wide range of colors and styles, including tiles that look like wood which can be a great alternative if you still prefer the appearance of natural wood, but are prohibited in using wood decking due to local regulations. Since there’s no need to construct any foundations with bearers or sleepers, installation is much easier than building a conventional wood deck. And as porcelain pavers are so much lighter than concrete pavers, they can be relatively easily transported to a rooftop, using a goods elevator if available.

Not only is this pedestal paver system applicable to residential applications but it is equally suited to constructing commercial large plaza decks on hotels or other commercial buildings.
