1 - Description of pedestals The adjustable pedestal parts are: 1- load-spreading base: ø = 208 mm (or 340 cm²), with a rounded edge to avoid damaging A the waterproofing membrane, equipped with multiple perforations to drain away surface water. 2- pedestal head: ø = 120 mm (or 113 cm²) with a top surface of either: A a . Pedestal tile: 4 fins at 90° angles leaving a regular gap of 3mm between tiles, for draining away surface water and preventing cigarettes and other debris falling onto the waterproofing membrane. The fins can be snapped off (using simple thumb pressure) to enable edging or...

4.2 - NF DTU 51.4 Building works Exterior wooden decking Extract 1: 5.2.4 Laying decking onto polymer pedestals This document only concerns the following specific configurations for laying wooden decking planks onto polymer pedestals: - Type 1 decking on polymer pedestals laid on concrete floor or stabilised level rough ground with a minimum load bearing capacity of 2 bars. For this type of construction, the maximum thickness of the decking planks is 27mm. NOTE the stabilised rough ground is set at paragraph 3.9. The head height of the polymer pedestal should be adjustable and must be...

Extract 2: 4.5 Pedestals made from synthetic materials Pedestals made from synthetic materials described in this NF DTU, designed for type 1 decking planks, must comply with the following requirements: — the base of the pedestals must have a level surface of a minimum size of 300cm2 ; — the upper part of the pedestals must enable the joists to be fixed in at least two points; — in the case of pedestals supporting joists at their junction point, the surface area of the upper part of the pedestals must not be smaller than 50cm2 with a minimum width of 57mm; — in the case of pedestals for...

5 - Packaging The products are packaged in an easily identifiable manner. Each pedestal has a sticker with a barcode, fixed to the underside of the plate. The 2 heights (Min and Max) are engraved onto each pedestal, in 2 different places (on the pedestal head and on top of the plate) enabling the pedestal to be identified even if dissassembled. The pedestals are assembled then packaged in woven polypropylene bags, which can be manually carried and therefore practical for installers. Each bag comes with documentation on the type of pedestal, its Min and Max height, as well as a 3D image)....
