Adjustable pedestal 50/80 mm for slabs, tiles or ceramics - Jouplast

The preparation of the ground depends on the surface on which you will lay your tiled terrace on pedestals:

• If you are laying on an old terrace or a concrete paving, all you have to do is clean the surface and check its flatness;
• On the other hand, if your future tiled terrace takes place on grass, earth or gravel, you will need to prepare the ground beforehand.

This ground preparation will guarantee the durability of your tiled terrace on pedestals over time. Yes, unprepared ground can evolve and move depending on weight and weather conditions.

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

Without structural work or additional tools required, 4 steps are enough to prepare your land to accommodate a paving terrace on pedestal:

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 can be made upstream by depositing a layer of 30/60 or 40/80 type crushed gravel.

If the surface obtained still has some defects, it is recommended to make a laying bed with quarry sand or crushed sand type 0/4. This will facilitate the installation of low height pedestals.
