Big advantage of the terrace pedestal method: they adapt to any type of terrain. They are even capable of leveling sloping ground! On the side of the support, apart from a geotextile film to prevent the growth of weeds, nothing in particular: bare ground, gravel, concrete paving or old terrace... You can put your pedestals on the ground you want. Note, for installation on the lawn, we still recommend that you prepare your site a little. Small earthworks will be necessary to guarantee the stability of your construction.
To do this, loosen your soil over 15 cm, lay a geotextile film and cover with gravel over about 15 cm. Once this earthwork has been completed, all you have to do is put your terrace pedestals on the ground. Your pedestals do not need to be fixed because with the weight of the pavings or joists for a wooden terrace, they will be weighted and will not move.
