vloerdek

Vloerdek is a Dutch architectural and engineering term that denotes the structural element that forms the horizontal surface of a floor and also functions as a deck in maritime or raised-floor contexts. It encompasses the platform that supports both the load-bearing structure and the finishing floor surface in buildings, ships, and similar constructions.

In shipbuilding, a vloerdek refers to the deck that forms the floor of compartments and working spaces. It is typically constructed from steel, wood, or composite materials and is designed to bear loads, provide access, and resist environmental conditions such as moisture and corrosion. The deck may be integrated with hatch openings, watertight boundaries, and service routes as part of the vessel’s overall structural system.

In land-based construction, the term is used for the deck that supports a floor layer on mezzanines, podiums, or raised floors. Such systems often employ decking panels laid over a substructure of steel beams, concrete slabs, or timber joists. Depending on the application, a vloerdek may include a concrete topping, fire-resistive layers, or other finishes to meet durability, acoustical, and safety requirements, as well as provisions for services and drainage.

Etymology: the term combines Dutch words vloer (floor) and dek (deck). The concept is common in Dutch-speaking construction and maritime industries, where distinctions may be made between a structural deck and a finished floor surface.
