Abstract

A fibre reinforced cement flooring sheet (1) that is suitable for use in wet area flooring, is lower in density than conventional compressed fibre cement wet area flooring, and is nailable. The flooring sheet (1) includes connecting means (2) on longitudinal edges permitting the sheet to be interlockingly engaged with adjacent sheets to form a substantially coplanar support surface, suitable for use in wet areas.

Description

technical field [0001] The present invention relates to flooring, and in particular to wet area flooring. The present invention has been primarily developed for the provision of wet area plank floors and reference is made to this application description hereinafter. It should be understood, however, that the invention should not be limited to this particular field of use. Background technique [0002] The following discussion of the prior art is intended to bring the present invention within its proper technical scope and to enable a fuller understanding of its advantages. However, any discussion of prior art throughout this specification should not be considered as expressing or containing an acknowledgment that the art is widely recognized or forms part of the common general knowledge in the art. [0003] One known method of laying a foundation for wet area floors involves adjoining sheets of pressed fiber cement side-by-side across the desired wet area, and subsequently...
