Floor installation systems
Screed work
Ducts and accessory parts only obtain their full load capacity for correct use through the fixed
composite with the screed. For this, the following preconditions are of importance:
– The duct system must be sealed before screed is applied
– All the system elements are permanently anchored on the raw ceiling
– The installed duct system may neither be walked on nor subjected to any other loads
– Any hollow spaces created must be filled with screed
– The duct system may only be subjected to loads after the screed has hardened and must
be blocked off prior to this
– Screed deformations and shrinkages must be observed in advance
With a screed-covered duct, it is essential that the screed thickness above the duct corresponds
to the value stated in the standard, in order to avoid crack formation.
The nominal screed thickness is dependent on the insulating layer, the individual load and the
screed type. For more detailed information on screed types and the nominal screed thickness,
refer to DIN EN 13318, DIN EN 13813, DIN EN18560. Here, under certain circumstances,
chemical or thermal impacts may occur, which may require additional measures to protect the
installed system.
Screed-flush ducts (BKF/D and BKW/D) and floor boxes (UDHx,UDBx, UDSx) must be levelled
to the intended height before screed laying (construction side height line). The screed layer
should check the levelling height.
Smooth and compress screed well on the screed-flush ducts and floor boxes (no insulation
strip). Only this achieves the required load capacity.
The BKB/BKG screed-flush duct system is decoupled from the screed using an insulating strip,
as it could otherwise lead to damage to the screed and/or floor covering.
Screed types
When selecting the screed structure, it is necessary to clarify which screed mortar types are
possible for the application. There are difference types of screed mortars.
Flowing screed:
Before screed application, these tasks must be observed and completed:
– Duct system and boxes are to be weighed down --> Floating of the screed
– Duct system and boxes are to be sealed against the ingress of flowing screed and pro-
tected on the construction side
– Side profiles and film must be jacketed with sufficient screed.
– Avoid cavities
Aggressive screed:
When using aggressive screed types, all the metal parts must be insulated during construc-
tion using a chloride and alkali-free bitumen layer or other suitable means (VOB Part C).
Corrosion:
Corrosion on metallic underfloor components is reduced to a minimum when
– The maximum moisture content of screeds corresponds to DIN EN 1264-4.
– Underfloor ducts are ventilated sufficiently for drying.
