The Jouplast Essentiel 155/245 mm self-leveling pedestal is the ideal foundation support for building a tiled terrace, in porcelain stoneware, concrete slabs or wooden duckboards on sloping or uneven ground. Adjustable to the millimeter from 155 to 245 mm via the gray nut under the head, it automatically compensates for level defects thanks to its pivoting head, up to 5% slope over 1 meter.

Advantages

• Quick and easy installation
• Installation on uneven or irregular ground
• Compensates for or creates a slope of up to 5% thanks to the pivoting head
• Installation without fixings or joints
• 4 break-off spacer tabs, 3 mm thick, for an easier layout
• Manual, millimeter-precise adjustment with the gray nut

Installation tips

This pedestal is intended for outdoor pedestrian use, on uneven ground such as crushed gravel. Prepare the ground (excavation 15 cm, geotextile membrane, 30/60 or 40/80 draining layer, compaction) to ensure the longevity of the terrace. Allow a fall of 1 cm per linear meter for rainwater drainage, and lay self-supporting slabs of class T7 or T11 (standard NF EN 1339 or F+). Allow 1 pedestal per corner, i.e. 4 pedestals per slab; add 1 to 2 pedestals in the center for large formats. At this considerable height, pay particular attention to the plumb and stability of each pedestal.

Bituminous membrane compatibility

This polypropylene pedestal with a wide base is compatible with bituminous and PVC membranes. Add a protective layer (geotextile membrane or cushioning slab) under each pedestal to avoid any risk of abrasion. To be avoided on membranes: pedestals with a metal base, without a wide base or with mechanical fixing, which could puncture the membrane and void the waterproofing.

Warnings and good practice

• Slabs only: not designed for joists or secondary wooden structures.
• Slab thickness: preferably at least 2 cm for stability and longevity.
• Jointless installation between the slabs to preserve the waterproofing of the whole assembly.

Technical specifications

Tip: always check the finished height of your project, adding 2 cm for the tiles. Complete your order with the Jouplast acoustic rubber pad, slab support plate and slab carrier for comfortable installation.
