The raised installation method allows utility systems to be inspected at any moment and conveniently houses all piping; it also compensates for unevenness in the ground.
Watch the video and find out how to perform a correct raised installation.
1. Clean the existing surface and check that the screed is level to select the right type of pedestal. The screed must be dry and cured. Prepare the chosen pedestals, cutting the ones around the edge to size and removing any unwanted wings.
2. Arrange the grid of pedestals in accordance with the laying diagram, starting with those around the edge. Fit the protective tile edge clips on the pedestals against any walls.
3. Lay the slabs on the pedestals dry. Add a pedestal in the middle of the slab, removing the spacer wings. Systematically check the flatness and adjust the heights of the pedestals with the adjuster key to compensate for any unevenness in the substrate. A little slope of the substrate is always recommended in order to prevent water stagnation underneath the surface.
