We often hear questions whether the tiles laying on the adjustable pedestals will crack on the terrace? What are adjustable paving slab supports? This is your main concern when choosing a ventilated terrace as an external cladding solution for your terraces, balconies, patios, etc.
Below we will try to explain what to look for when choosing terrace tiles. So that during the long years of using the surface of the terrace, your tiles based on adjustable pedestals do not crack.
Each adjustable pedestals has a strength approximately 1000 kg. (more information you can found here). Therefore, there is no need to worry about the durability of terrace adjustable paving slab supports. They will certainly withstand the pressure of tiles and heavy items placed on the terrace / balcony.
Then you should follow the recommendations and support the boards resting on the adjustable pedestals in the middle.
Each adjustable pedestals has gap spacers. Thanks to them, we can define equal gaps between the tiles. However, they can be easily removed. When we remove the gap spacers, we can lift the adjustable pedestals up by a few millimetres and put it under the center of the tile. Thanks to this, we can easily create a support that we can place centrally under the tile.
The dimensions of the tiles usually go into a oblong. For example, 30x120, 40x120 or 45x90, and each manufacturer determines what distance the board should be supported in order to maintain its strength.
When we look at a 40x120 tile, we can easily come to the conclusion that we have to support it every 40 cm. So in one direction at two extreme points. In the second one, additionally in two places of length, i.e. 0 - 40 - 80 - 120 cm.
Concrete has its own specific physical properties. It is a very brittle material. Thanks to the increase in thickness, the concrete tiles can be fully safely supported in points on adjustable paving slab supports .
It is what generates correct use for the next years.
If the ground moves, it will cause the adjustable paving slab supports to move. Also their collapses. And this, as a result, will generate negative effects. It will prevent the facing boards from having adequate corner support. We will expose them to cracking.
Tiles laying on both adjustable pedestals and support pads must have excellent, stable support. This will give them strength and will prevent excessive stresses that could cause cracking. In addition, the terrace will not have curves, which has a large impact on the comfort of use and visual aspects.
Such negative effects are not caused by the poor support of the panels on the supports, but by the poor quality of the panels themselves.
If the boards we purchase are adapted to point support on adjustable terrace supports, the adjustable paving slab supports will certainly withstand their pressure.
