Touching floor slab
Under the floor slab, a layer of polystyrene approx. 5 cm
thick with an excess depth of around 20 cm must be
included in order to prevent any settling of the concrete slab
leading to large vertical loads in the chamber.
Otherwise the chamber could have the effect of a stake.
The chamber structure must be designed in such a way that
the polystyrene layer is on level with the height-adjustable
upper section.
(1) 5 cm polystyrene layer
If the taper is in the transition area of the floor slab, sepa-
ration must be by means of a moving joint t = 5 cm and the
polystyrene layer must be fitted above the chamber area , as
described above.
