PROBLEM TO BE SOLVED: To provide a lining sheet for concrete form which prevents dust and others from entering into the space between a lining sheet and a form panel so as to form a beautiful concrete surface while performing dehydration and deaeration excellently.SOLUTION: A lining sheet 1 for concrete form to be attached to the inner side of a form panel 5 for use comprises a nonwoven sheet 20 having water permeability and air permeability, and a porous resin layer 10 with water permeability and air permeability which is composed of elastic resin foam applied to one surface of the nonwoven sheet 20 and which has a large number of non-through holes opened and exposed only to the front side so that the front side functions as suction cups. At least one of the nonwoven sheet 20 and the porous resin layer 10 has a characteristic nonpermeable to concrete particles.SELECTED DRAWING: Figure 1 |
