Narrow strips of screed material, laid and compacted to finished level, should be used to establish the level of the screed. Immediately after laying the strips, the infilling screed material should be placed and compacted. Where the edge of a strip forms a daywork joint it should be formed or cut to produce a vertical joint. Alternatively, screed battens, carefully levelled and trued, should be fixed at the correct height for the required thickness of screed. Battens should be removed before laying the adjacent bay of screed. At daywork joints all bedding screed beneath the battens should be cut away to form a vertical joint.
The screed material should be spread on the prepared base with adequate surcharge, thoroughly compacted, either by heavy tamping or by mechanical means, and levelled with a screed board.
