Frequently Asked Questions

To ensure the stability of your terrace, it is essential to install your pedestals on properly prepared ground. Installation directly on soil, without earthworks or stabilisation, is strongly discouraged: the ground may settle or move over time due to weather conditions (rain, drought) or the weight of the structure. We recommend using our pedestals on raw, pre-stabilised ground or on a concrete slab. In both cases, the substrate must be clean, stable and well levelled to ensure the long-term durability of your project.

The spacing between pedestals depends on the type of wood and the size of the joists you are using. As a general rule, we recommend a distance of 70 cm between each adjustable pedestal. For the joists, we suggest a center-to-center spacing of 50 cm if your decking is made of natural wood boards. Please note that these guidelines differ for composite decking.

Jouplast self-levelling pedestals are durable and guaranteed for 10 years in accordance with our general terms and conditions of sale and our recommendations for use. They are highly resistant to UV rays and frost, as well as heavy loads of up to 1 tonne per pedestal. This makes them a robust and stable support.

Jouplast® flat decking pedestals are sturdy and resistant to heavy loads. More specifically, they have a crush resistance rating of over 1 tonne. However, it is important to note that the maximum load supported by wooden, composite or slab decking on pedestals does not depend solely on the strength of the pedestals.

Each type of decking has its own load-bearing capacity. To find out more precisely how much weight your wood, composite or slab decking can bear, we recommend that you contact your supplier or the decking manufacturer.

The Profildeck® fixing clip for clip-on profiles allows you to finish the edges of your decking quickly and easily. Simply install the accessory along the joist or at the end of the joist, secure it with a structural screw, and clip the Jouplast® finishing profile onto the accessory.

No, 10mm riser pedestal height extenders can’t be stacked.

Jouplast 2mm flat packers are thin packers designed specifically for use where minimal packing is required. Their snappable design means they can be used in one-piece or snapped into 2 or 4 sections to provide 4 packers in 1. They also ensure excellent ventilation for timber decking structures, and comply fully with the minimum spacing requirement set by the French DTU 51.4 technical standard (3 mm between joist and decking board). Ultra-strong, they can support heavy loads with no deflection (crush resistance in excess of 2 tonnes).

The paved terrace side cladding support is compatible with standard Essentiel adjustable paving riser pedestals, with the exception of the 8/20 pedestal and all the self-levelling pedestals. It is also compatible with Essentiel decking pedestals from 40 mm upwards.

The Cleman® self-levelling 55/80 riser pedestal is designed and used to create tiled, ceramic or paved terraces for pedestrian use. Its self-levelling system compensates for gradients of up to 5% for effective levelling and maximum covenience during installation.

The Cleman® adjustable 28/40 riser pedestal is designed for tiled, ceramic or paved terraces for pedestrian use. It ensures precise levelling using a three-stage adjustment system: pre-setting using the driver bit, manual setting using the screw adjuster, and final adjustment using the special adjustment wrench. This riser pedestal ensures structural stability, is easy to install and offers optimised terrace side cladding. The paving used must be self-supporting and compliant with French classification T7, T11, or F+. Not compatible with the paved side finishing plate.
