SHEET FOR APPLYING A PREDEFINED PATTERN ON THE SURFACE OF A CONCRETE ELEMENT DURING ITS MANUFACTURING, SYSTEM AND METHOD USING THIS SHEET FOR THE MANUFACTURING OF A CONCRETE ELEMENT

摘要

This sheet (10) comprises: - a main layer (20) of polymer material, a contact face of which (22) is intended to come into contact with a surface of a volume of liquid concrete during a manufacturing operation of a concrete element by formwork or molding, the main face having hydrophobic properties; - an attachment layer (40) for securing the sheet to a support surface; - the contact face (22) being textured and comprising for this purpose a plurality of three-dimensional structures (32) projecting relative to the main layer (22) and forming in relief a predefined graphic pattern (30) intended to be printed on the surface of the concrete element.
