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.
Claims37
A fibre reinforced cement bound flooring sheet that is suitable for use in domestic wet area flooring, is lower in density than conventional compressed fibre cement wet area flooring, and is nailable, wherein said flooring sheet has a bending strength sufficient to withstand a uniformly distributed load of up to 5 kPa when supported at 450 mm centres along its length.
A modular flooring system for a wet area, said flooring system including at least one flooring sheet, and complementary connecting means permitting said flooring sheet to be interlockingly engaged with an adjacent sheet to form a substantially coplanar support surface, wherein said at least one flooring sheet has a bending strength sufficient to withstand a uniformly distributed load of up to 5 kPa when supported at 450 mm centres along its length.
A modular flooring system according to 26, wherein said connecting means include tongue and groove formations disposed respectively on opposite longitudinal edges of each flooring sheet, whereby the tongue on one sheet and the groove on the adjacent sheet cooperate to provide secure interlocking engagement between adjoining sheets.
A modular flooring system according to claim 59, wherein the flooring sheets are formed substantially from a fibre reinforced cement formulation including microspheres, pearlite or volcanic ash.
A method of installing a modular flooring system comprising the steps of aligning two or more of the flooring sheets on a support platform and engaging connecting means on the adjoining sheet so as to form a coplanar support surface wherein each of the flooring sheets has a bending strength sufficient to withstand a uniformly distributed load of up to 5 kPa when supported at 450 mm centres along its length.
