The panels are directly put down on heads of jacks provided with a gasket conductive shock absorber.
Pedestals are generally stuck on the basic ground with a specific adhesive.
They allow a regulation level of the raised floor.
The fixation of a possible earth wire can be realized by springing or crimping (according to request).
The panels are put down on stringers
Stringers can be added to improve :
- the horizontal stability of the floor ,
- the waterproofness of the plenum ,
- and\or the resistance to the load.
Applicable in particular for heights of floors superior to 500 mm or zones subjected to frequent passages of rolling loads.
