  In addition, in the overlap of the lath material and the sheet-shaped waterproofing material in the lath composite, the portion where another lath composite is not adjacent has an area that overlaps the vicinity of the edge of the lath composite including the overlap. Lath composites (for example, one-fifth the width of commonly used lath composites) can be used in layers. Such lath composites for the vicinity of the edge include, for example, one of the front bones and one of the back bones, the other being arranged at intervals, and there are a plurality of predetermined locations on the straight line at intervals. Can be. Cross joints of surface bone projections and back bone projections in the lath composite for the vicinity of the edge, and cross joints of surface bone projections and back bone projections in the commonly used lath composite It can also arrange so that a part may overlap.
