The substructure of FLOOR and more arena is made of pre-fabricated steel profiles which are simply screwed together by using connectors.

The most different kinds of subfloors can be considered with the planning.

The substructure can be installed on even as well as on sloped concrete subfloors. Also an already existing stepped subfloor is no problem.

The substructure is installed directly on the subfloor, however, acoustical decouplings can be considered with the installation.

• The horizontal calcium sulphate elements are glued together with the already proven FLOOR and more interlocking.
• With standard step runs (800-1200mm) the installation elements are pre-fabricated to the respective height.
• Revision openings and installations notches (step lighting, air outlets) can be already considered with the production of the calciumsulphate installation elements.
• Usage of the resulting cavity as a presurre floor (open air ducting): The subfloor is coated with a special 2-component epoxy resin subfloor sealant. The installation elements can be provided with an aluminium foil at the lower side as an additional humidity barrier.
• Trapezium or round steps make a radial realisation possible.
• One layer structure of the step planking
