Frequently Asked Questions

The Cleman® self-levelling 40/55 pedestal is designed and used to create tiled, ceramic or paved terraces for pedestrian use. Its self-levelling mechanism compensates for uneven ground and gradients of up to 5% to facilitate stable installation on irregular surfaces.

The surface on which the terrace will be built must be prepared before work can begin. Unprepared ground (e.g. unprepared soil or lawn) may change over time and can be subject to movement. Depending on the weight it will subjected to and the local climate (dry periods, heavy rainfall, etc.). For these reasons, it is important to stabilise the ground beneath the terrace to ensure its long-term stability.

Jouplast® ridged wedges are suitable for all joinery projects requiring precise adjustment and high levels of stability. They are typically used in timber decking projects and for packing indoor flooring. Their robust design and ease of use make them an essential accessory for professional and DIY installers who want to carry out effective, durable upgrading projects.

We offer 2 types of finish for raised patio:

1. The first option is a patio edge finish using cut tiles and the combination of our paved side finishing plate and paved side cladding support.
2. The second option for paved patio is to use our finishing profile.

Yes, paved side finishing plate support kit extenders can be stacked. Either 1 or 2 of these extenders can be stacked to add up to 40 mm of extra height. You can therefore adjust the height of finishing plate supports to suit the needs of your project without compromising the stability and strength of the overall installation.

The Essentiel 25mm pedestal height extender is an accessory designed to raise the height of standard Essentiel paving pedestals. It can be used to adjust the height of raised patios surfaced using ceramic tiles, stone, concrete slabs or timber decking tiles. These height extenders offer excellent loading characteristics and are fitted with snappable packers.

Maintaining an exotic wood deck is essential to preserve its beauty and durability. Here are some key steps for effective maintenance:

Regular Cleaning:

• Sweeping: Regularly remove leaves and debris to prevent dirt buildup.
• Washing: Use water and a soft, non-metallic brush to clean the surface. You can add a suitable anti-moss product if necessary.

Restoration:

• Brightening Products: Apply a wood brightener to restore the natural color of the wood. Follow the product instructions for application time and rinsing.

Protection:

• Saturator: Apply a saturator after cleaning to protect the wood from UV rays and moisture. This helps maintain the wood’s natural color.
• Protective Oil: An oil can also be applied to give a wet look and prevent graying.

Seasonal Maintenance:

• Spring and Autumn: Perform a thorough maintenance twice a year, before and after summer, to prepare the wood for changing weather conditions.

We are often asked about the benefits of patio pedestals and why they are preferable to traditional glued installations or those without adjustable pedestals. There are many reasons! Patio pedestal systems offer numerous advantages.

Firstly, using pedestals simplifies both planning and installation. Indeed, our products are designed to simplify the installation of your patio, whether the flooring is made of tiles, composite, timber, mixed, or low-height decking boards. Height-adjustable pedestals generally allow for fast installation without the need for major groundworks.

Terrace pedestal systems also offer great adaptability, flexibility and modularity, making it easy to modify the layout to suit the owners’ changing tastes and needs over time. This modularity is particularly advantageous for temporary or evolving installations.

Made from recycled materials, Jouplast® pedestals are sustainable, stable, long-lasting supports with excellent resistance to temperature fluctuations and crushing. They are very resistant to heavy loads and can support 1 tonne. Their design includes an ingenious screw system that prevents sagging over time. They also provide proper drainage of rainwater.

In addition, terrace pedestals are practical and help you save money by reducing construction costs and minimising environmental impact as they are made from recycled materials.

Another significant advantage is that an adjustable pedestal support system can be used on various types of ground, whether level, sloping or uneven. Our self-levelling pedestals, for example, allow you to compensate for or level out a slight slope, making it easier to install outdoor patio areas on varied terrain. Whether you want to landscape your garden, balcony, poolside area or even a space with a pergola, pedestals will be your allies for your landscaping project.

Thanks to the space beneath the raised floor, it is possible to route cables and pipes, making it easier to install electrical or plumbing systems without the need for additional work. This makes it easier, for example, to incorporate lighting into your outdoor living space.

In short, Jouplast® patio pedestal systems offer a practical, economical and durable solution for patio projects, whilst meeting the requirements of both professionals and DIY enthusiasts.

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.

Our Modulesca® concept is 93.4 cm wide.

The Essentiel® 10mm pedestal height extender is used to increase the height of patio pedestals. Suitable for raised patios surfaced using timber decking tiles.
