Adjustable pedestal

The adjustable pedestal is set to the desired height by simply screwing, to the millimeter. It makes up for differences in level and makes the terrace perfectly level, from a balcony to a large outdoor terrace.

Pedestals adjustable to the millimeter

The height is set by simply screwing, accurate to the millimeter, giving a perfectly level surface on every type of substrate. Laid without glue or grout, a terrace on pedestals stays removable and drains perfectly: water runs off through the joints, air circulates under the slabs and utility ducts pass beneath the surface.

This category brings together our Jouplast and YEED ranges, in adjustable and self-leveling versions.

Our experts' tip: first set the four corner pedestals of the terrace, stretch a string line, then align the intermediate pedestals with it: you will save valuable time.

Frequently asked questions

Which pedestal height should you choose?

Choose the adjustment range that covers the target finished height: the height of the threshold or French door to respect, minus the thickness of the slab. It is best to allow a range with some margin; beyond the pedestal's maximum height, add an extension.

Why choose terrace pedestals?

For a level terrace with no concrete, free-draining, ventilated, removable and quick to lay. Pedestals make up for defects in the ground, hide utilities and drains, and allow renovation without demolition.

How many terrace pedestals do you need per m²?

It all depends on the slab size you will lay. For a 60x60 slab, allow 4 pedestals (one on each side); beyond that, allow 5 to 6 pedestals per slab. A large format reduces the number of pedestals, a small format increases it. For 60x60 slabs in a straight pattern, allow about 5 pedestals per square meter. A layout plan is needed to work out the exact number of pedestals. We are available to help with this.

What does a terrace on pedestals cost per m²?

It depends on the pedestal range and on the size and quality of the slabs. Excluding accessories, pedestals cost about €9 per m2. You then need to add acoustic rubber pads, slab support plates, finishing profiles and your surface covering. Overall, allow about €60 per square meter including the surface covering. Pedestal installation remains competitive because it avoids the cost of concrete and bedding labor.

How do you calculate the weight a terrace on pedestals can bear?

The permissible load depends on the capacity of one pedestal multiplied by their density per m², and on the strength of the slab. For a heavy localized load (spa, planter, tub), add more pedestals under the footprint and check the slab. In everyday use (furniture, foot traffic), the margin is very wide.

What is the maximum height of a terrace pedestal?

An adjustable pedestal alone generally covers 8 mm to 23 cm. With stackable extensions, you can reach much greater heights, for example 47 cm (excluding the surface covering) with Jouplast Essentiel pedestals.

How do you adjust the height of a pedestal?

The head screws in or out on its base to go up or down, to the millimeter. An adjustment key lets you make changes even after the slabs are laid, through the joint.

What adjustment range is available?

Each model covers a given range, from a few millimeters to more than 200 mm depending on the range. Our height categories let you filter directly by the height to make up.

Can an adjustable pedestal bear heavy loads?

Yes. Pedestals designed for 20 mm porcelain stoneware are built for intensive residential use and easily bear garden furniture, planters and daily foot traffic.
