Combination floor

The combination floor has been developed as a ground floor above crawl spaces for house-building and commercial and industrial building. The combination floor is extremely suitable as a foundation for a stony finish and is manufactured in accordance with the KOMO product certificate. The combination floor is supplied in 2 types: for loads of up to 3 kN/m2 and equipped with a stronger reinforcement, and a 10 mm thicker finishing layer for higher loads.

The table below states the technical specifications for the combination floor:

	Up to 3 kN/m2  variable load	More than 3 kN/m2 variable load
beam height	170 mm	170 mm
base width	120 mm
head width	60 mm
thickness of finishing layer above beam	30 mm	40 mm
thickness of finishing layer above filler element	40 mm	50 mm
minimum reinforcement	Ø 5 - 250 mm	Ø 6 - 200 mm
concrete infilling (excl. support)	55 l/m2	65 l/m2
unladen weight	1,73 kN/m2	1,97 kN/m2
unladen weight incl. finish (50 mm)	2,73 kN/m2	2,97 kN/m2

The standard distances between centre-lines of the beams (630 mm and 510 mm) are extended with sizes of 600 mm and 480 mm, with a new standard length of 1250 mm. Thanks to a completely new method of manufacturing the EPS filler element, the use of recycled EPS and the use of higher quality concrete and prestressing steel, the price remains competitive.
