Adjustable pedestal 140 230 mm for slabs, tiles or ceramics - Jouplast

The entire installation is simplified to make life easier for the user and save him a lot of time. In fact, even if the preparation of the ground is a mandatory and meticulous step, it is within everyone's reach and does not require any major work. Indeed, if the surface that will host the terrace on pedestal is concrete, a simple cleaning of the ground is necessary as well as a conscientious check of the flatness of the ground.

If, on the other hand, your surface is rough, there will be some small work to be done, but to be accomplished without great difficulty. This preparation of the ground is essential to protect your tiled terrace on pedestals from the passage of time and bad weather such as heavy rain or drought. By preparing your soil, you stabilize it. Good news, this step is very simple!

Here is what you need for this preparation:

• A cord
• Stakes
• A spirit level
• A shovel
• A tape measure
• A mason's box screed
• A geotextile film
• Gravel

And for the implementation:

1. Dig the ground for 15 cm;
2. Place a geotextile felt there to eradicate the growth of weeds and save you additional maintenance;
3. Fill the hole with a 15 cm layer of gravel;
4. Compact and make sure everything is level.

Depending on the nature of the ground, a draining foundation may be necessary. To do this, first lay down a layer of 30/60 or 40/80 crushed stone.

If the surface obtained still has some defects, you can make a laying bed with quarry sand or type 0/4 crushed sand.
