Frequently Asked Questions

The lifespan of a wooden deck depends mainly on the quality of the structure.

That is why we advise you not to neglect this part of the deck, even though it is hidden.

When installing your decking, you must ensure that the weight is evenly distributed, that the structure is ventilated and protected from rainwater with a protective strip, that the boards are spaced correctly, etc. All these details matter.

To ensure your wooden deck on pedestals has a long life, it is also important to maintain it regularly. To do this, remember to protect and clean it regularly. Take care of your wood, and it will take care of you!

Fixego® is not suitable for composite boards or wood species that are knotty or unstable, such as acacia.

Before installation, check that the screws provided are compatible with the wood species used, as some species are not suitable.

All our stabilisation grids can support weights that are perfectly suited to traffic:

• Alveplac® and Greenplac® can support up to 600 t/m² when filled with gravel or grass.
• Urbangravel® can support up to 800 t/m² when filled with gravel.
• The entire URBANIT® range, designed for heavier traffic, can support up to 1000 t/m² with grass, gravel or paving stones.

The mechanical strength of our grids is the fundamental criterion in our development process to ensure soil stability.

Jouplast® pedestals have a crush resistance of over 1 tonne. However, the weight that an elevated wooden deck on pedestals can support does not depend solely on the strength of the pedestals.

Each type of wood has its own strength. We therefore advise you to consult your timber supplier for more precise information on this.

More generally, if you are planning to place a heavy item on your deck on pedestals, such as a hot tub or a pergola for example, we recommend opting for our PROFILDECK® solution, which will better distribute the weight across the structure of the deck.
