That portion of a building which must withstand the greatest abuse and yet that which has not received material attention until comparatively recent times is the floor. The first floors of primitive man were the stone floors of his cave. Modern man still uses stone in the form of marble, terrazzo, concrete and similar materials for the floors of many of his buildings. A substantial advance in primitive buildings came with the use of wood floors but here again, advancement is limited to the natural progress of learning which woods were best fitted for this type of service and the development of surface finishes or treatments which would preserve them and render them less liable to staining and marring.
It was not until man turned to composition surfaces that material advance in floor engineering was achieved. While the old principle was one primarily of structural materials, the new principle became one of a laminated floor using the structural sub-floor for strength and a composition surface for resistance to abrasive wear and for decorative value.
The first significant step was the discovery and development of linoleum. A tough and resilient material, basically composed of
