Frequently Asked Questions

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.

The way you choose to finish a terrace built on riser pedestals depends primarily on whether or not you want a neat finished look. To help you visualise what a terrace without a finished side looks like, imagine the side view of your riser pedestal terrace and its exposed components… The appearance is not very attractive, and it certainly doesn’t look very professional. Our terrace side finishing options also make it possible to hide cables and pipes beneath the raised terrace. Neat terrace edges are the finishing touch that makes all the difference and creates a professional appearance.

Yes, it is essential to prepare the ground before installing PLOGOM low-profile decking pedestals: for installations on concrete slabs, make sure to remove any debris that could compromise pedestal installation and/or stability.

The Essentiel® 60 mm pedestal height extender is an accessory designed to increase the height of patio pedestals by 60 mm. It is compatible with Essentiel® adjustable paving and decking joist support pedestals. It provides a practical solution for raising the height of your patio without compromising maximum stability.

The Cleman® 130/230 mm patio pedestal must be installed on stabilised ground or a precast concrete slab. It must be positioned under the paving in accordance with the recommendations of the paving manufacturer, with at least one pedestal at each corner of each paving slab. Its height adjustment mechanism can be used before, during and after installation to ensure quick and precise adjustment.

Yes, MODULESCA® steps can be customised to suit your own preferences. They can be clad using timber, ceramic tiles or paving slabs to blend in with your garden design and project.

It takes around 10-15% longer to lay decking using Fixego® than with conventional methods. The fact that the initial preparation stage requires greater accuracy, explains why it takes a little longer. The time taken to prepare and install joists is the same.

To use the Jouplast® paving grab, simply hold the ergonomic handle tightly to maintain a secure grip on the paving slab. For user safety, it is important to handle this tool with care, especially when moving paving slabs.

The 2.5% slope corrector for Essentiel pedestals compensates for gently sloping ground when constructing a raised patio. Positioned directly under the pedestal, it provides up to 2.5% of slope correction to ensure a flat, stable terrace surface. Its use is essential to ensure optimum installation of paving slabs or decking joists, especially on gently sloping sites.

Begin by placing the 21 cm joist in the central housing moulded into the module, and the two 35 cm joists in the side positions. Then secure all 3 by screwing through the module. Once the joists are in place, you can clad the steps by screwing the timber decking boards directly onto these sections of joist.

Stabilized gravel should be laid with a preliminary excavation of 10 cm for a pedestrian walkway. For a driveway, we recommend excavating the soil to a depth of 20 to 30 cm.

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.

Jouplast decking pedestals come with a 10-year guarantee, subject to our installation guidelines and terms and conditions of sale.

Composite boards have an average lifespan of 20 to 30 years, though this will depend on the environmental quality of the materials. Solid boards are more robust and durable than hollow boards. Gentle, regular cleaning will help extend the lifespan of your decking. The UV protection on the boards is also important for withstanding high temperatures.

To build a straight or quarter-turn outdoor staircase using Modulesca®, the minimum slope of the ground must be 46% and up to 70%. Outside these two slope limits, it is impossible to install our Modulesca® staircase for your landscaping projects.

A base layer composed of 0/31.5 crushed stone must be laid to level the ground. This must then be compacted using a vibratory plate compactor.

Depending on the nature of the soil, a draining foundation layer can be laid using 30/60 or 40/80 crushed stone.

If the resulting surface is still uneven, we recommend laying a bed using quarry sand or 0/4 crushed sand. This will make it easier to install low profile pedestals.

We recommend using the vibratory plate compactor between each layer.

A raised composite wood patio has many advantages, but there are also some disadvantages to consider.

Composite decking on pedestals can be more expensive than a natural wood decking. It is easy to find good-quality, low-cost timber. As composite is a process that combines two materials, this is less often the case.

Composite, and particularly smooth boards, can be prone to scratches and may require regular cleaning to prevent unwanted stains.

When it comes to your raised-slab patio, the choice of one type of edge finish over another depends mainly on your personal taste in outdoor design. For a look similar to a light or beige slab – such as a travertine-effect finish – opt for the pearl white RAL 1013 edging profile. For a look with darker slabs closer to grey, opt instead for the RAL 7016 anthracite grey profile. If you prefer an industrial or even metallic look, we recommend choosing the range of aluminium grey profiles.

The choice of edge finish for your raised patio depends primarily on your landscaping preferences.

• For a look compatible with light-coloured or beige paving, such as a faux travertine, for example, the preference might be a RAL 1013 Oyster White profile.
• For a look compatible with darker paving closer to grey, a RAL7016 Anthracite Grey profile might be preferable.
• If you prefer an industrial or even metallic look, our advice would be to choose from the grey aluminium profile range.
• If you prefer to match the colour of your paving to the rest of your raised patio, we recommend that you opt for a cut tile edge finish and use the paved side finishing plate and paved patio side cladding support.

Yes! Jouplast low-profile decking pedestals, such as the Plogom flexible paved patio pedestal, are made from recycled materials. The fact that the material is more eco-friendly does not make them any less weatherproof or UV-resistant; quite the opposite, in fact! They are therefore highly resistant to extreme weather, including frost, and UV.

Yes, up to four 60 mm height extenders can be stacked on a single pedestal. This solution allows you to achieve the terrace height you require without compromising structural stability and strength. It is important to respect this maximum limit in order to ensure the reliability of the installation.
