How to calculate how many adjustable pedestals per m2 you need

How much should you place the adjustable pedestals so that the terrace is stable and serves for years

If you plan to install a ventilated terrace based on adjustable pedestals, whether fixed height or adjustable ones, and you are wondering how to calculate pedestals for pavers - you've come to the right place! We will explain how to correctly calculate the demand for your scope.

Calculating the number and height of adjustable pedestals is, from our experience, one of the biggest challenges in the implementation of a ventilated terrace. Both for individual customers and companies handling the order; sellers and contractors.

We meet this challenge and will try to answer the question of how many adjustable pedestals per m2 are needed and guide you step by step on how to calculate pedestals for pavers for a ventilated terrace.

Types of terraces and how the difference in their size affects how many adjustable pedestals per m2 do you need

Basically, there are two basic types of ventilated terraces - balconies and terraces on the ground / roof terraces.

Balcony terraces are a type of terrace that is by definition small. The distances between the wall and the railing are small, which makes it necessary to cut the panels. As a result of the small size of the terrace and the cut tiles, how many adjustable pedestals per m2 will be greater than in the case of a terrace on the ground or a roof terrace.

Ventilated terrace on the ground

Terraces on the ground are usually terraces in the garden on the ground floor. The nature of such a terrace is mainly a recreational space or sometimes in the case of e.g. restaurants, hotels, etc. Terraces on the ground are usually larger in size. Such a terrace is usually designed to accommodate at least a table for the whole family with chairs. A ventilated terrace on the ground, whether in an adapted place or at the design stage, usually has no problems with the existing boundary limitations. On the one hand, it is adjacent to the building wall, and the other edges of the terrace are not limited by the open space.

The above features of a terrace on the ground mean that such a terrace will need fewer adjustable pedestals per m2 than a balcony.

Ventilated terrace on the roof

Buildings constructed today certainly have an additional value, which is the possibility of adapting flat roofs to usable space. Both traditional and inverted roofs can be used as a ventilated terrace.

Roof terraces, as well as terraces on the ground, usually have a larger area, so the number of adjustable pedestals per m2 will be smaller than in the case of a balcony.

Regardless of whether it is an adaptation of a terrace in an existing building or a terrace in a newly built facility, it should be carefully measured because the actual as-built dimensions may differ from what was designed.

Dimensions can be made with an ordinary measure and written down manually on a piece of paper or you can print a project of such a terrace and make measurements with a laser meter.

Since the technology of ventilated terraces allows you to raise the terrace to any height, we need to determine at the very beginning at what height we want our terrace to be installed. From our experience, usually the key point in relation to which we determine the height of the terrace is the threshold to enter the terrace from inside the building. Even if several entrances / windows lead to the terrace, they should be at the same height.

It should also be considered whether the height of the terrace will provide us with a comfortable entrance to this terrace and whether its height will look favorable from inside the building. A terrace that is at the same height as the floor in the room looks good.

The easiest way to measure the height is with a long spirit level, one edge of which is set at the zero point of our terrace and set horizontally. We will notice that the distance under the spirit level changes. We should measure these heights between the spirit level and the ground. It is best to take measurements at a distance corresponding to the positioning of the adjustable pedestals under the tiles or joists. So if, for example, stoneware tiles 60x60x2 cm are placed on the terrace, the height measurement should be made every 60 cm.

Attention!

Please note that point 0 is our upper terrace area on which we will walk.
The thickness of the material to be laid on the terrace should also be subtracted from the measured height.
For example, if we measured a height from point 0 to the ground equal to 10 cm.
From 10 cm, you should subtract the thickness of, for example, the already mentioned gres tiles, i.e. 2 cm.
The result obtained is 8 cm. This is the height that the adjustable pedestals must have at this point on the terrace.
Height-adjustable pedestals have their own height ranges, so check which adjustable pedestals model you are catching in this range.

In this particular case, 8 cm, it could be the **ADJUSTABLE PEDESTALS STANDARD series** for tiles with a height regulation of 7-12 cm (70-120 mm) (i.e. 8 cm height is ok).

We have already measured the dimensions and area of the terrace.

We have already measured the height of the adjustable pedestals we need.

Now we need to answer the question of how many cm such adjustable pedestals will have to be spaced.

Adjustable pedestals for tiles usually supports the tiles in the corners and sometimes (if the tiles manufacturer recommends it) also in the middle under the tile. The tile must not show any tension that are visible to the eye. You can additionally try to jump on such a tile. The tile must not crack under load.

In the case of tiles, the size of the tile determines the distance between the adjustable pedestal. Ask the board manufacturer about the recommended support points for the tiles, i.e. how many times should the supports be placed under the tile.

TERRACE FROM BOARDS - ADJUSTABLE PEDESTALS UNDER THE JOISTS - WHAT IS THE SPACING OF THE ADJUSTABLE PEDESTALS?

In the case of a terrace made of boards on joists, the adjustable pedestals have two distances between them

The stiffness of the board determines this distance. Ask the manufacturer of the board, every cm recommends support on the joist.

The adjustable pedestals will be placed at the same distance because they are located directly under the joists.

If you want to make sure that the chosen distance is correct, you can support the board at two points and stand on it.

The board should not sag.

This is shown in the photo below.

This distance is determined by the stiffness of the joist used. Ask the manufacturer of the joists, every cm they recommend to support the joists.

If you want to make sure that the chosen distance between the adjustable pedestals is correct, you can support the joist on the adjustable pedestals and stand on it.

The joist should not sag.

This is shown in the photo below.

When the previous steps have been completed, we can start calculating how many cantilever we will need per m2
