Frequently Asked Questions

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.

The Cleman® adjustable 80/130 mm paving pedestal is designed and used to create tiled, ceramic or paved terraces for pedestrian use. Its three-stage adjustment system (pre-setting using the driver bit, manual setting using the screw adjuster, and final adjustment using the special adjustment wrench) facilitates precise levelling. It ensures terrace stability, facilitates corner installation and offers optimised terrace side cladding. It is compatible with self-supporting paving compliant with class T7, T11, or F+. Not compatible with paved side finishing plates.

Here are the criteria to consider when choosing garden border edging:

• Which areas you want to border: flowerbeds, footpaths, lawns or aggregate?
• How would you like your outdoor space to look: modern, rustic, minimalist or contemporary?
• Which material do you prefer in terms of appearance: stone, metal, composite, concrete or plastic?
• What is your budget: metal, plastic and stone are more expensive, but will last longer. Timber is often more affordable, but tends to deteriorate more easily.
• What level of maintenance are you looking for: natural materials like timber and stone require regular upkeep to avoid deterioration. Plastic, composites and metal offer greater weather and frost resistance.

The lifespan of timber decking depends primarily on the quality of its structure. That is why our advice is not to neglect this aspect of the terrace project, even though it will not ultimately be visible. When constructing a decked terrace, ensure that its weight is evenly distributed, the structure is adequately ventilated and protected against rainwater by joist protection tape, and that the decking boards are spaced correctly, etc. All these details are important.

The paving spacers are designed to create even spacing between paving slabs as they are laid to guarantee uniform spacing across the terrace and comply fully with all project constraints. Ideal when laying paving slabs, tiles and even timber decking boards.

Each slope corrector for Essentiel riser pedestals can correct for gradients of up to 2.5%. Gradients of up to 10% can be corrected by stacking up to 4 slope correctors.

The MODULESCA® connector kit is designed to join MODULESCA® components together side by side, so you can create a new set of garden steps or extend existing steps to the required width. It uses a connector pin and clip to link two MODULESCA® modules or steps together.

To ensure the permeability of a commercial paved parking lot, here are some recommendations:

• Use URBANIT® stabilizing plates: Our plates are designed to allow the natural infiltration of rainwater into the soil. They are ideal for creating permeable parking lots.
• Choice of pavers: Use smooth pavers without irregularities to ensure stable installation.
• Proper installation: To make your parking lot permeable, it is essential to properly prepare your soil and interlock the URBANIT plates to ensure optimal permeability.
• Regular maintenance: Keep the parking lot clean and ensure that the spaces between the pavers are not obstructed by debris. Excessive debris can prevent proper water infiltration.

By following these recommendations, you can create a paved parking lot that allows for effective rainwater management and helps reduce the risk of urban flooding.

The spacing between pedestals will depend on the size of the slabs you are using.

As a general rule, one pedestal is needed at each corner of the slab.

For example, for 60 x 60 cm slabs, the pedestals should be spaced 60 cm apart in both directions.

For larger formats (such as 90 x 90 cm or 120 x 30 cm), it may be necessary to add a pedestal in the centre or along the sides to ensure proper support.

Always refer to the manufacturer’s recommendations for your slabs to determine the ideal spacing.
