Advantages and Constraints of a Deck on Pedestals
JOUPLAST® pedestals are designed to facilitate the construction of decks, meeting the expectations of outdoor space professionals, landscapers, and DIY enthusiasts, while offering numerous layout and finishing possibilities.
In this article, we detail some advantages and constraints specific to installing a deck on pedestals.
Advantages of a Deck on JOUPLAST® Pedestals
Simplified Layout and Assembly with JOUPLAST® Deck Pedestals
JOUPLAST® deck pedestals are primarily designed to simplify the installation of slab or wooden decks by DIY enthusiasts, outdoor space professionals, or landscapers. Consequently, JOUPLAST® deck pedestals have naturally become popular among outdoor space professionals, who can now better organize their work time and meet increasingly ambitious demands. For example, as mentioned in our article on this topic, it is entirely possible to install a spa on a deck on pedestals.
With CLEMAN® pedestals, you can easily adjust the height of a tile by a few millimeters using an adjustment key, even after the tiles are laid and your deck is completed. Additionally, with the slab plate system, you can achieve invisible lateral finishes or 45° angled finishes (CLEMAN® range).

JOUPLAST® Deck Pedestals for Economical and Durable Slab or Wooden Decks
JOUPLAST® deck pedestals contribute to the democratization of modular and non-permanent deck construction, whether it be wooden or slab decks. Thus, if the owner of a deck changes tastes or revises ambitions, this modularity allows for easy modification of the deck configuration without destruction and within a controlled budget. Additionally, the design of JOUPLAST® pedestals makes them durable over time. Indeed, in addition to the height adjustment system mentioned earlier, JOUPLAST® pedestals are equipped with an ingenious screw system that prevents them from sinking over time (it should also be noted that JOUPLAST® pedestals are designed to be resistant to crushing and temperature variations). JOUPLAST® deck pedestals are made from recycled materials, which, coupled with their durability, enhances their compatibility with environmental concerns.
Points to Validate Before Considering the Installation of a Deck on Pedestals
Anticipating Ground Level Elevation
As you know, deck pedestals allow you to adjust the ground level, which you can adapt according to the height of your home’s thresholds. This is calculated beforehand, but it is indeed possible to design a deck on pedestals flush with the threshold of your home, pool, or spa by playing with the different sizes of JOUPLAST® pedestals and their adjustability. JOUPLAST® even offers the smallest adjustable pedestal on the market for this purpose.

Attention to Ground Stability
Deck pedestals offer numerous advantages. However, their modularity and the non-permanent nature of the layouts they allow also stem from the fact that they are not fixed in the ground. Therefore, it is essential to ensure they are placed on a sufficiently leveled surface that remains stable, even in heavy rain.
Conclusion
Depending on the ground to be developed, JOUPLAST® offers different ranges. For regular ground or on a concrete slab, we recommend the standard pedestals from the ESSENTIEL or CLEMAN® range. For installation on prepared ground (gravel) or on a slope, the self-leveling pedestals from the ESSENTIEL or CLEMAN® range will allow installation on uneven ground. Finally, we also offer a system that allows the installation of a wooden deck without ground preparation via the ELEVO® anchoring pile pedestal system.
