Frequently Asked Questions

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.

Composite patios tend to age well when the raw material is of high-quality and the deck is well maintained. Pay extra attention to the resistance of the composite boards and the installation system to UV and frost.

By installing composite boards on our Profildeck aluminium joist system, the installation is rot-proof and highly durable over time, even in saline environments such as coastal areas.

The finishing touches on a raised patio are essential to ensure your patio looks neat and finished.

There are several options to finish the edges of your raised patio:

• If you wish to extend your patio into a garden area, you can do so using garden edging strip, for example, and our Modulesca modular garden steps to descend from your patio into your garden.
• If you are building a raised decking patio, we offer a lateral riser support for wooden decks.
• For finishing a raised paved patio with cut tiles, we have a lateral riser support and a side finishing plate.
• If you wish to create an edge without cut tiles, we sell clip-on finishing profiles in various colours for a both practical and neat finished edge.

Adding a finishing touch to your raised patio or not depends mainly on whether you want a finished look. To help you visualise a patio with or without a side finish, imagine looking at your raised patio and the entire installation from the side. It does not look very attractive, and the result does not look professional. Another advantage of edging a raised patio is that it allows you to conceal cables and pipes beneath the patio. Finishing the edge of your patio is that little extra touch that makes all the difference, just as a professional would do.

The geotextile membrane separates the distinct sub-layers of the soil.. This makes it possible to separate sand from aggregate, for example. The geotextile membrane also prevents weeds from growing in the gaps between the gravel.

Yes, our terrace edge finishing profiles, paved side finishing plate and paved terrace side cladding support are all suitable for use with terraces on sloping or uneven ground. In practice, it is not the finishing accessories that adapt to the slope, but the paved terrace riser pedestal. Adjusting the height of the riser pedestal makes it possible to compensate for a slope or uneven ground and to finish the edges of your terrace using our finishing profiles, paved terrace side cladding support and paved side finishing plate. However, we strongly advise you to prepare the ground thoroughly to create a level, even surface and avoid any unpleasant surprises in terms of poorly corrected slopes.

Jouplast 90mm ridged wedges are construction accessories designed to wedge and level timber structures in general, and flooring, decking and bordered floors in particular. Their saw-tooth ridging system provides precise height adjustment from 14 to 20 mm. They ensure stable, secure adjustment with no risk of slippage, and are compatible with flat packers. Ultra-strong with crush resistance over 2 tonnes. Our ridged wedges can be screwed, glued or nailed in place.

With a height adjustable up to 230 mm, the Cleman® self-levelling 130/230 pedestal is ideal for creating raised tiled, ceramic or paved terraces for pedestrian use. It can be used to compensate for uneven ground and gradients of up to 5% for perfectly level terraces.

The Cleman® 80/130 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.

Polyethylene zone markers are designed to fit Greenplac, Urbangravel and Urbanit stabilisation modules. They are used to create dividing lines or surface signage, and simplify the process of marking out driveways, footpaths, pedestrian-only and traffic-only areas. They are frost and UV resistant.

The Jouplast® Elevo decking pedestal for metal posts is designed to create natural timber or composite decking on sloping ground and for extending existing decking. It requires no site preparation and is inserted directly onto a square metal post (not supplied) to provide a stable and height-adjustable solution.

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.
