1. Top of the pedestal
The top of the pedestal has a surface of 190 cm² (diameter of 155 mm), and is reinforced with several reinforcement veins. In the top a hole is foreseen in which the spacer tabs or rawplug for mechanical attachment of the decking material, can be inserted.
2. Base of the pedestal
The supporting base of the pedestal has a surface of 315 cm² (diameter 200 mm). Minimum thickness of 3 mm of polypropylene to ensure stability. The stand has a 125 mm diameter cylinder as well as 8 reinforcement veins of 5 mm thickness for stability and load distribution. The supporting base has 2 water weep holes to allow any liquid to run freely, and 2 x 4 holes with diameters 4 and 8 mm for possible attachment of the stand to a concrete, wood or steel supporting surface. These 8 holes are aligned with the 8 reinforcement veins to ensure stability.

3. Slope corrector - PH5
The slope corrector device is made of polypropylene and will be clipsed on the head of the pedestal (DPH0 - DPH3); the DPH4- and DPH5-pedestals have the slope corrector integrated in its heads. With the PH5 it is possible to build a perfect level terrace or decking on top of the pedestals.
By rotating the top part of the slope corrector, it is possible to adjust the angle which can be set in values between 0 and 5%. This adjustment can be done in steps of 0.5; so an adjustment of 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5 and 5.0 cm/m can be done. The value of the step is shown in the window on the top. The direction of the slope into which the slope corrector should be directed, is indicated by an arrow numbered with the same values which is also shown on top of the slope corrector.
If it is required to get a bigger slab bearing surface for increasing the stability of the pedestals then the pedestals can be turned upside down (base becomes top) and the direction and value for slopes to be corrected are also indicated undersurface of the base of the pedestal, so that also in upside down position, the slope corrector can be used correctly.

4. Coupler - C2
The coupler is used for reaching heights over 170 mm by adding this to the pedestal DPH5. The coupler has two 2 cylinders with screws; it is also equipped with a safety clip system to avoid unscrewing. The inner thread cylinder has a diameter of 105 mm and has 4 vertical veins on its outer side for reinforcement. A 3 mm thick plate is situated in the centre of the inner cylinder with reinforcement bars to guarantee the stability of the coupler. This plate has 8 water weep holes to allow water or chemical products to flow freely. The outer screw cylinder has a diameter of 102 mm.
A pre-setting for the required height on the site before doing the installation is also possible with the combination of two letters and two signs “+” or “-” printed at the pedestals and at the couplers. So a worker can adjust all pedestals to the required height by using the letters and signs.

5. Spacer tabs - A2 to A10
The spacer tabs are used to create a uniform gap between the slabs placed on top of the pedestals. They are available in different widths, depending on the space required by the architect and they are made replacable. The following sizes are the standard available widths: 2, 4.5, 6.0 or 10 mm thickness.
The spacer tabs are cylindrical plates, which can be clipsed onto the surface of the supporting head of the pedestals. They are free to rotate at 360°. Even with the slope corrector installed on top of the pedestal, it is possible to freely rotate the position of the spacer tabs. There is an 8 mm hole in the centre of the plate which allows a rawplug and fixing screw to be used to fix the 4 slabs onto the pedestal head if necessary. For decking material without any apparant joint, special spacer tabs with 2 mm separators are available. Also it is possible to clips the same spacer tabs undersurface of the supporting base. At wall edges, the two pre-cut blades of the spacer tabs can be broken to allow the two slabs to be laid. In wall corners, the spacer tabs can be unclipped by using a small screwdriver and the corner of the slab rests then entirely on the pedestals head.

6. Shims - E10 + E20
Shims are used to reduce the sound and to adjust small differences in thickness from the used tiles. They are available in 1 and 2 mm thickness and are made of EPDM.
The shim is a disc with gaps for placing it directly on top of the spacer tabs on the pedestals. The wings can be taken off in case of the necessity to make an adjustment between tiles with different thicknesses.
