Screed structure
3 Basic principles of screed
3.1 Screed structure
The screed structure is a key precondition for the correct installation of underfloor systems. With
screed-covered floor systems, it is essential that the screed thickness above the trunking corresponds
to the value stated in the standard, in order to avoid crack formation.
The screed is located above the load-bearing storey ceiling or above the floor plate and beneath floor
covering.
The nominal screed thickness is dependent on the insulating layer, the individual load and the screed
type. Refer to DIN EN13813 for more information on the nominal screed thickness.
The minimum nominal thickness
1
is regulated according to the hardness class (DIN EN 13813) for per-
pendicular payloads ≤ 2 kN/m².
Under some circumstances, chemical or thermal loads may occur, which require additional measures
to protect the installed system.
The electraplan.BK screed-flush duct systems and the BKSA underfloor sockets only receive their load
capacity for correct use through being joined with the adjacent screed.
For this reason, the following points are important and must be observed:
– After the trunking system has been permanently installed on the raw concrete, then the system may
no longer be walked on or subjected to similar loads
– The trunking system must form a composite system with the adjacent screed
With electraplan.BK, the following points must be particularly observed:
– The side profiles need to be supported with screed, in order to achieve a good static support in the
screed. The screed is to be carefully worked and compacted
– The opened duct system may neither be walked on nor subjected to similar loads. Measured for the
necessary protection must be taken in agreement with the construction management
