Before laying your first paving pedestal on the ground, it is necessary to dwell on it. If your surface is an old terrace or a concrete screed, no problem, you can install your paving terrace pedestals.
On the other hand, if it is a rough ground, it is essential to prepare your ground in advance. Why now? Quite simply to guarantee the stability of your surface and the longevity of your tiled terrace on pedestals. Indeed, with the weather conditions (drought, heavy rain), the weight supported by your terrace and the passage of time, your ground can change and cause your terrace to move. To protect yourself against this, a simple and quick preparation of the ground is necessary.
- Dig 15 cm deep over the entire surface of your future terrace;
- Place a geotextile felt over the entire surface to prevent the growth of weeds between the wooden boards;
- Cover with crushed gravel;
- Compact everything to obtain a flat and loose surface;
- Check the flatness of the surface with a spirit level.
