A system floor is a modular floor construction . A substructure made of supports forms the support for a base course. On the room side, this base layer forms a level room boundary to accommodate floor coverings and the loads acting on them. The cavity under the base layer can be used flexibly for installations for data and power supply and for supply and disposal lines of all kinds.

There are two basic types of construction for system floors. One type of construction is called a raised floor . Individual slabs laid from industrial production allow free access to the floor cavity at any time and at any point. The second type of construction is called a hollow floor . It is characterized by a continuous, closed base course, which only allows access to the floor cavity via inspection openings. The development of system floors in the form of raised floors began in the 1960s with the emergence of large IT rooms. With the necessary installation of the numerous cables in the floor cavity, safe and practical cable routing in the rooms could be guaranteed. In the decades that followed, the increase in the number of new administrative and office buildings with IT equipment required further developed and more economical solutions. The solution was found in the hollow floor. Both types of construction provide the basis for flexible use of space and accessible building installation for the requirements that are placed on functional buildings today.

As a structural interior construction element, the system floor has to absorb the loads from use and pass them on to the supporting structure. System floors are used for different uses of building surfaces. This results in additional requirements for noise and fire protection as well as for electrostatics and hygiene for the system floors, in connection with the construction methods as well as the integration into the room-defining interior construction.

According to the specifications of the European Commission , system floors are a security-relevant expansion element. The engineering demands on this building product, the liability and building supervision issues for system floors in the planning, tendering and execution processes are essential reasons that the companies in this sector have joined forces in the Federal System Floor Association.

Building law

The admissibility of system floors in Germany according to building regulations is based on the system floor guidelines that have been introduced in each federal state.
