How this node works
Instead of meeting the wall in a sharp corner - which would crack and let water under - the cocciopesto is turned up the wall in a concave fillet, the sguscia. This rounds the floor-to-wall junction into a continuous, seamless tray, the same trick that made cocciopesto the lining of Roman cisterns. A vapour barrier under the screed cuts off rising damp, the floor’s chief enemy, before it can reach the lime and bring salts.
