Abstract (en)
[origin: WO0129342A1] The invention relates to formwork with a filtering wall, comprising a load-bearing frame provided with a filtering wall (3) on at least one of the surfaces thereof, whereby said filtering wall has holes of specific dimensions so that surplus water can be drained off from the concrete and the concrete aggregates can be retained. The formwork is characterized in that the filtering wall (3) is comprised of a flexible skin (3A) which is kept at a specific distance from the load-bearing frame by means of spacers (4) and tensioned in at least two orthogonal directions by tensioning means.
