Frequently Asked Questions

The support fits onto the riser pedestal flange base. Used to finish the edges of paved terraces and timber decking for outdoor pedestrian use only. In combination with a paved side finishing plate, it can be used to create a number of different configurations, including plinths, concealed finishes and garden step trades. Used alone, it can be used to create a butt-jointed finish. Allow one support per riser pedestal around the perimeter of the terrace or decking. When planning corners, the recommendation is to allow two supports. The support is fixed securely and invisibly in place using the glue trap system, and requires no screw fixings.

The Cleman® 80/130 mm riser pedestal can be used on stabilised uneven ground or an existing concrete slab. It is not recommended for use on loose ground.

Der Cleman® Stellfuß wird ausschließlich auf stabilisiertem Boden oder auf bereits vorhandener Betonplatte verlegt. Er ist für weiche oder unvorbereitete Böden nicht geeignet und muss auf einer ebenen Fläche mit Höhenunterschieden unter 1,5% verlegt werden.

Once the deck boards have been laid in accordance with French building regulation DTU 51.4., Profildeck® screws are screwed directly through the decking board and into the aluminium joist, using a maximum torque rating of 7 Nm (position “18” on a 20-position 18V cordless combi drill). It is important to check that the screws are compatible with the material used, particularly in the case of composite decking boards, which may require specific fixing methods.

The Jouplast® Elevo riser pedestal for metal posts can be installed on all types of ground, including slopes and loose or uneven ground. It is ideal for sites where traditional preparation (excavation, concrete slab casting etc.) is not feasible, and enables quick and stable construction.

3mm stabilising spacers are inserted between paving slabs as they are laid. They can also be used in combination as intersection spacers, depending on the configuration of your installation. Once installation is complete, the spacers can be removed for a sleek final finish.

The Cleman® and Easio® riser pedestal height extender adds 60 mm to the initial riser pedestal height. By stacking up to 4 height extenders, the initial height can be increased by total of 240 mm.

MODULESCA® 20 cm steps are used to create modular garden steps. Manufactured from glass fibre reinforced polypropylene, they are ultra-strong and rot-proof with a load-bearing capacity of more than 6,000 kg. They are the ideal solution for creating straight and curving garden steps. They can be used to widen existing MODULESCA® module steps or to create new flights of narrow steps.

We can reasonably estimate the cost of a gravel courtyard for a private individual, if self-installed, to be between €15 and €30 per square meter. For this approximately 100m² driveway, you should therefore budget at least €1500 for materials, including gravel and cellular paving grids, which seems to be a very reasonable budget for a durable, aesthetic, and ecological arrangement. Your gravel driveway will also be accessible to people with reduced mobility (PRM), which is an additional advantage.

On top of the gravel stabiliser, it is recommended to lay 2 cm of gravel with a grain size of 5/15 or 8/16 so that all the cells are filled (for ALVEPLAC). Once the gravel has been laid on the gravel stabilisation plate, the plate should no longer be visible.

Before installing adjustable pedestals, it is important to stabilise the ground to ensure the durability of your wooden or slab terrace. Regardless of the installation context, the ground must be flat, levelled and free of any obstacles.

On concrete slabs, be sure to remove any contamination that could interfere with the installation and stable support of the pedestals.

On raw ground, it will be necessary to carry out minor earthworks in a few simple steps :

• First, you will need to excavate your ground in order to start with a flat base and ensure that the ground is properly levelled.
• The installation of a geotextile and the creation of a crushed stone foundation layer are then essential in order to be able to accommodate the adjustable pedestals in good conditions.

If installing on a waterproof surface, comply with DTU 43.1.

If installing with our Elevo® pedestal for metal posts, soil preparation is minimal and simply requires the installation of a geotextile for proper rainwater drainage.

Your joist pedestals must be installed on a prepared raw surface or a concrete slab. We strongly advise against installing them directly on bare soil without stabilization, due to the risk of ground settling or shifting caused by weather conditions (rain, drought) or the weight of the structure. Whether you place your pedestals on a raw surface or a concrete slab, the base must be clean, stable, and well-leveled to ensure the long-term durability of your deck.

All self-levelling pedestals for terraces can support a maximum load of 1 tonne per pedestal. Can you imagine? One tonne is the equivalent of a giraffe.

Extra-flat pedestals can only be used on flat, level floors with no difference in level exceeding 1.5%. In addition, pedestals can only be installed on stabilised ground or existing concrete slabs.

Is your floor uneven? Don’t panic, you can fix this by following a few simple floor preparation steps. For more information, please refer to our installation advice documents.

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.
