Wallbarn’s Universal pedestals are a freestanding system that create a cavity between the decking/paving surface and sub-deck, this allows obstacles such as pipes and cables to be concealed and out of the way and keeps it ventilated. This means that no fixings are made through the membrane underneath, this is ideal for warm roofs and inverted waterproofing systems. They also come with an integrated acoustic shim on the headpiece. Even flat roofs are built to a small fall to allow adequate drainage. Their durable adjustable pedestals have a telescopic stem which allow you to make millimetre-precise manual adjustments in height in order to achieve a flat upper surface. Wallbarn’s Universal adjustable pedestal range is suitable for both paving and decking. They are particularly ideal for porcelain tiles on flat roofs and podiums and are available in heights from 35mm up to 380mm. Laying decking Adjusting the height of the pedestals, rather than cutting furring’s means installers can install decking onto structural decks much more quickly. Pedestals are adjusted to accommodate the fall in the roof deck. Placed a maximum of 600mm apart, the joist bearers are simply slotted between the joist holders. A joist framework is constructed to create a sturdy, stable, weight-bearing surface to take the upper surfacing. The top decking is then fixed onto the joists using ordinary wood screws or hidden fixings. Height adjustments can be made whilst the timber joist framework is in place, saving time and labour. Paving applications Positioning lugs create uniform spacing between each slab, allowing rainwater to run between and under the slabs, so no standing water is left on the surface. As it is a suspended system, the weight of the slab is what holds everything in place. If required, any height adjustments can be made whilst the slab is in place. This saves on labour and time. As the lugs are 10mm high, they are ideal for supporting thin or thicker tiles. Lugs can be snapped by hand for stretcher bond and irregular laying patterns. Raising the decking off the sub-deck allows water to drain freely under the decking so there is no standing water left on the surface, preventing ponding and associated slip hazards, and extending the lifespan of the timber. Joists are not standing directly on the waterproofing membrane, or insulation, preventing damage to it.
