Frequently Asked Questions

No, we recommend that only one height extender is used per patio pedestal. We do not recommend stacking of these height extenders, because doing so may compromise the stability and strength of the finished patio.

Building a deck on adjustable pedestals with exotic wood requires adhering to certain standards and regulations to ensure safety, durability, and compliance with local regulations. Here are the main points to consider:

Local Regulations:

• PLU (Local Urban Plan): Check with your local town hall for specific rules in your municipality. Some areas may have particular restrictions, especially regarding height and aesthetics.

Declarations and Permits:

• No formalities if the deck is less than 5 m² and at ground level.
• Prior declaration for a deck between 5 m² and 20 m².
• Building permit for a deck over 20 m² or elevated more than 60 cm.

Construction Standards:

• Minimum Height: A minimum height of 64 mm is recommended to ensure the deck’s stability.
• Accessibility for People with Reduced Mobility (PMR): If the deck needs to be accessible, comply with accessibility standards, such as a maximum slope of 6% for ramps and a minimum width of 90 cm.

Installation Techniques:

• Ground Stabilization: Use adjustable pedestals placed on a geotextile to prevent vegetation growth under the deck.
• Drainage: Ensure a minimum slope of 1 to 2% to drain rainwater and avoid stagnation.

Installation on slopes of up to 15% is possible for vehicular traffic (integrated anchoring system).

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

Greenplac® can support up to 600 t/m² when filled with grass.

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

Installing a deck with Fixego® takes approximately 10 to 15% longer than traditional installation methods. The initial installation requires greater precision and therefore takes a little longer. However, preparing and installing the boards takes the same amount of time.

Whether you will need planning permission or not to create your raised terrace patio will depend, among other things, on the height, the surface, the type of patio you envision, and its location. We advise you to contact your city’s council before starting any construction work to check the local building codes that apply to your situation.

The best times to install a raised decking area are spring and autumn, as the temperatures are milder. However, installing a raised patio requires little ground preparation. It is therefore entirely possible to install it in the winter.
