Abstract (en)
[origin: EP2540934A1] A covering (10) for formwork (22) for concrete castings (24) reinforced or not, for the realisation of building works positioned so as to cover the walls or inner surfaces of the formwork made of wood, plastic or metal, with said covering defined by a tape or sheet (12) suitable for being wound on a reel (14) from which it is unrolled and cut and comprising at least two layers of which one is of polyolefin material and one of expanded or foam material, respectively, suitable to support dilations and absorb the stresses and shrinkage of the concrete during the setting and subsequent hardening phase and to prevent adherence with the concrete casting (24).
