The ease of installation and the absence of heavy work offer real time savings in the assembly of your terrace. Only intended for the construction of terraces for pedestrian use, the brand offers very high quality products for a safe and solid terrace over the years.


Simplified site preparation

Before proceeding to the construction of your wooden terrace on adjustable pedestal, the ground must be clean and the ground must be stabilized. Easy, quick and less expensive, site preparation is mandatory before proceeding with the installation of the pedestals, except in the case of installation on a concrete slab.

No need to carry out major work, the Jouplast joist terrace pedestal makes your life easier! Quick to install and effortlessly, you will quickly enjoy a terrace of great strength.

To do this, follow these steps:

  1.        Proceed to the disbursement of the soil of its earth on 15 cm of depth;
  2.        Then lay down a geotextile that will prevent the growth of weeds, followed by a 15 cm layer of gravel ;
  3.        Finally, compact the whole thing.

Your soil must be compact and stable to be able to accommodate the wood terrace pedestal properly.


Can be installed on any surface

The ground preparation allows the adjustable pedestal joist to be placed correctly on any support. Whether your plot is for a wooden terrace on land, grass, concrete or an existing terrace surface, the pedestal adapts easily to any type of ground. However, the final surface must be loose to accommodate future construction. The pedestal offers you additional time savings because to place it, you just need to lay it on the ground without adding any fasteners.


Quick and easy to install

Accessible to all, the joist pedestal is suitable for both professional and private requirements. The installation of a wooden terrace on pedestal can be done without outside help thanks to the ease of handling. It is carried out without the slightest difficulty as it takes only 3 days to build your outdoor space!

Of course, before starting construction work, prepare your installation with the help of an installation plan in order to plan the number of pedestals and boards needed. Only 4 steps are required to install the foundations of your terrace:

  1.        Determine the location of the pedestals (which must be parallel) and their spacing. Determine the location and spacing of the pedestals (which must be parallel) and the required distance between them. We advise you to leave 70 cm between each pedestal for a good load distribution. Once this is done, position the pedestals directly on the ground. Finally, adjust them to the desired height using the adjustment ring located under the head of the pedestal for terrace, which allows adjustment to the millimeter;
  2.        Place the joists on the head of the pedestals. Make sure that they are all at the same height using a spirit level;
  3.        Screw the joists onto the lugs provided to ensure excellent support;
  4.        Attach the wooden slats to the joists. Use a screwdriver and wood screws to fasten the joists and the siding to each terrace adjustable pedestal. Your foundations are laid in no time!
