A sub-floor of a building, typically for a wet area, comprising a plurality of adjacent sections comprising a lowermost layer of substantially rigid foamed plastics material (12) and a glass fibre net (13) above the lowermost layer. Each joint is covered with a cementitious layer (14) on and through the net, a glass fibre and resin layer (15, 16), and a layer of dry aggregate. Preformed sections may define a slope for water drainage and suitable drainage channels (21). The sub-floor typically supports floor tiles (18) in use. |
