Preparing the Ground for a Terrace on Riser Pedestals

Preparing the ground for a terrace on pedestals

Implementing a terrace on pedestals is simple and quick. However, it requires proper ground preparation beforehand.

After marking the location of the future terrace, you have two options:

Creating the terrace on raw ground

• Ensure the area is clean and the ground is stabilized.
• Excavate the soil of its loose topsoil to about 15 cm.
• If there is a slight slope (up to 5%), it is not necessary to correct the level. Use the self-leveling pedestal to compensate for this slope and achieve a flat terrace.
• Lay down a geotextile.
• Create a draining foundation layer composed of crushed stone 30/60 or 40/80.
• Compact using a vibrating plate.

Creating the terrace on a concrete slab

• Check the available heights at the thresholds. Allow for a minimum of 3 cm.
• If the slab has a slope, use the self-leveling pedestal to compensate for it up to 5%. Similarly, if the slab has roughness.

Once the ground preparation is complete, you can start your terrace construction work.
