Abstract

A floor panel is provided for use in a sub-floor application. The floor panel has an upper member and a lower member. The upper member is made from a sheet floor material and the lower member is made from a waterproof sheet material. The lower member has a series of projections extending away from the floor panel and located adjacent to an underlying surface when the panel is in use. The projections allow moisture to drain between the floor panels and the underlying surface and also permit air circulation.
