Quantum Floor is a new type of pre-finished floor system which is considerably lighter than traditional pre-cast or in-situ concrete floor units, with building and substructure savings.

Quantum is a light system, at around 190kg/m 2, with units ranging in length from 5.1m to 11.4m.

Each Quantum Floor consists of a galvanised light-gauge cold-rolled steel section with concrete infill, and the connection system is selected to suit the building frame. The units are manufactured to steel tolerances rather than the concrete tolerances associated with traditional composite and concrete systems, with Quantum Floor unit-to-unit joints of only 10-20mm.

A lot of initial UK interest in Quantum has been for car parks, where the light weight and provision of an 'as supplied' working surface has proved attractive. In the Netherlands, interest is largely in conventional buildings. For weathering applications, such as car parks, a waterproof joint sealant is used. For conventional buildings a proprietary grout sealant is enough.

The flooring system is pre-finished in the factory, allowing floor finishes such as carpet and lino to be laid directly onto the 'as supplied' surface. No wet trades are required on-site, which gives significant health and safety benefits as well as programme savings compared with traditional systems. Quantum Floor is typically supplied as rectangular units, but more complex non-orthogonal building grids can also be accommodated.
