The actual finish will be specifically shown on the Drawings or in the Bill of Quantity. Lightweight concrete screeds for obtaining falls or as an insulation layer shall be of approved type of foamed concrete. The materials shall be measured, applied and cured in accordance with the manufacturer’s instructions and to the satisfaction of the Engineer or his Representative. In all cases the finished screed shall be of an approved proprietary type with a dry density of not less than 300kg/m3 to receive the applied roofing. Mixing shall take place using approved mechanical mixers. Concrete screeds for obtaining falls shall be (1:3:6) mix. All screeds shall be laid in bays not exceeding 10 square meters and formed between stop boards of the correct height and cut on each side to indicate the slope required in the roofing. The screed shall then be trowelled with a wooden float to true and accurate falls or cross falls up to the stop boards. A 10 mm side gap shall be left between each screed bay for the frill depth of the screed. The screeds shall be allowed to cure thoroughly to attain maximum shrinkage. Any cracks which appear due to shrinkage shall be made good. The gaps between bays shall then be filled in with cold bitumen. Where the roof screeds are to be reinforced with one layer of galvanized wire mesh, this shall be supported on top of the base on spacers to ensure that it is maintained at between 10 mm and 15 mm below the top of the finished screeds. It shall be at least 100 mm wide, securely wired together. It shall be stopped 20 mm from the edge of each bay.
