摘要: A shuttering used for forming concrete comprises a plate with a plurality of through holes opening on both its face and reverse, and a double woven fabric consisting of a face tissue which permits passage of water but prevents concrete from passing and a reverse tissue opposed to the face of the plate and relatively displaceable with respect to the face of the plate; the surplus water oozing out of placed concrete flows through gaps formed by the reverse tissue between said plate and the face tissue as well as the through holes of said plate.
