On Pedestals

Architrex structural wood tiles can be easily installed over sloping or uneven substrates using adjustable height pedestals placed under each corner of the tiles. Structural wood tiles are primarily designed as an alternative to more time consuming and expensive installations with straight run deck planks laid over wood bearers. The pedestal system greatly simplifies installation and resolves problems where no ‘permanent’ structures are permitted or where there are concerns that building materials may damage waterproof membranes.

The installation procedure for Architrex structural wood tiles is basically similar to installation of porcelain pavers on pedestal systems as described here. However the wood tiles are supplied with a slot cut in each corner enabling a special screw and washer component to be inserted. The screw is invisibly screwed into the pedestal head with the washer holding down the corner of the pedestals to “lock down” the tiles onto the pedestal, ensuring a safe, secure and level surface.

If any tiles need to be cut, it is very important that the structural integrity of the tiles is maintained. This may require relocating one (or two) of the support battens and re-attaching these to the slats from the underside of the tile. It may also be necessary to drill and countersink additional holes when re-inserting screws.

Its is also important that an adequate number of pedestals are used around the perimeter of the paved area, and that the tiles are restrained around the perimeter by a low wall or some other restraining structure to prevent the tiles from moving.

On-Grade

If installing solid wood tiles over a firm substrate such as concrete, they should not be laid directly on the substrate for the following reasons:

  • If wood is allowed to remain in contact with water for extended periods, some swelling of the bearers may occur and possibly temporary warping or twisting of the wood slats.
  • Unless the tiles are all laid parallel to the slope (and not in an alternating checkerboard pattern), the bearers on the underside will prevent water flowing freely underneath the tiles.
  • If the substrate is slightly uneven, the tiles could “rock” on the surface, or one or more of the edges may protrude upwards, creating a tripping hazard

For best results, we thus recommend laying the tiles on our 5/8″ high HD-PAD16  fixed height rubber support pads placed under each corner of the tiles.

For on-grade applications, our SwiftDeck range of interlocking wood tiles could also be considered.  With these tiles, the Ipe wood slats are screwed to a raised plastic mesh base, providing excellent drainage and enabling the tiles to be locked together by integral connecting tabs for quick and easy installation. Although the largest SwiftDeck tile is 24″ x 12″, two tiles can be connected side by side, effectively creating the appearance of a single 24″ x 24″ panel.

Post Installation Care

As supplied, Architrex structural wood tiles do not have any factory applied oil coating but are waxed at the ends of the slats only. We strongly recommend that tiles are coated with a good quality decking oil as soon as practical after installation to maintain the attractive wood color as long as possible and reduce the rate at which the wood will weather naturally to a silvery grey color. Also because the wax coating on the slat ends will tend to ‘bleed’ over time, if the tiles are not coated with a decking oil, it can often give the appearance that the ends of the wood slats have been saturated with water.
