Frequently Asked Questions

The most frequently asked questions to our experts

How much weight can joist pedestals withstand?

Jouplast® decking joist pedestals have a crush test resistance of over 1 tonne. However, the weight that a raised decking can support depends not only on the strength of the pedestals and whether they have a high load resistance, but also on the type of wood used for the decking. We therefore advise you to consult your timber supplier for more precise information on this matter.

More generally, if you are planning to place a heavy item on your raised decking, such as a hot tub for example, we recommend our PROFILDECK® solution (aluminium joists), which will allow for better weight distribution across the subframe structure of the installation.

How to use Fixego® secret fixing ?

Fixego® must be used for wooden decking projects that comply with French DTU 51.4 standards. It is fixed directly to wooden joists using screws.

Once installed, it holds the boards in place, creating regular spacing between them and promoting air circulation and water drainage.

We recommend using wooden joists made from the same type of wood as the decking boards. We do not recommend using Fixego® with wood that is knotty or unstable, such as acacia.

We do not advise using Fixego® on joists less than 45 mm wide.

Can I install finishing profiles on a sloping or uneven ground?

Yes, our finishing profiles, side finishing plates and support kit are compatible with sloping or uneven ground.

In fact, it is not our finishing accessories that adapt to the slope, but the pedestal. By adjusting the pedestal’s range of adjustment, it is possible to compensate for a slope or uneven ground and thus complete the finish of your raised patio using our side finishing profiles, support kits and side finishing plates.

However, we strongly advise you to prepare your ground properly to ensure a flat, even surface without any unexpected issues caused by poorly managed slopes. For more details, watch our video on ground preparation.

How to hide my decking pedestals?

There are several methods for concealing the joist pedestals on your raised decking.

If the clearance height allows it, you can create wooden side finishes for a uniform look.

For a finish at the end of the joist, simply place a lateral riser support on the base of the joist pedestal and snap off the tab. You can then more easily position and secure the joists. Do not forget to secure the vertical joist with a screw. You can finally attach the fascia board to the joist using 2 screws.

For a finish along the joist, you have two options:

  1. Create a “ladder” edge structure. To do this, you will first need to place a lateral rising support at the base of each pedestal and snap off the tab. Then, position perpendicular reinforcements around the edge to allow pedestal movement. Place a small vertical joist of the measured height against each lateral riser support and fix the fascia board to the joist using 2 screws.
  2. Add a peripheral joist. To do this, start by placing a lateral rising support at the base of each pedestal and snap off the tab. Then, position a small joist vertically against each lateral rising support and fix a spacer between the 2 peripheral joists to secure them together. Finally, simply fix the fascia board to the joist using 2 screws.

If your clearance height is too low, do not worry! We have alternatives to offer:

  1. Decorative pebbles can be an elegant solution. Placing pebbles along the edge of your decking will create a natural and attractive look that blends harmoniously into your outdoor living space. The pebbles add an organic and warm touch, whilst elegantly concealing the unclad sections.
  2. Another interesting finishing touch option for your raised decking is the use of small L-shaped corner pieces or finishing profiles. These 2×2 cm or 3×3 cm angles, depending on your needs, add a touch of structure and neatness to your deck. Easy to fix, L-shaped angles provide a stylish and durable finish to the edges of your elevated wooden deck.
