Concrete forms utilizing an improved concrete form liner comprising a two-sided fabric having a different range of pore sizes on one side compared to the opposite side. In one embodiment, a microporous coating, such as an ethylene-vinyl chloride microfoam dispersion, is placed on one side of a porous fabric (13) to controllably reduce the pore size of the fabric (13) on that side to between 0.2 to 20 microns. The coated fabric is used in combination with a support (11) and a grid (12) to form a concrete casting system (10) wherein the coated side of the fabric (13) is placed directly in contact with the concrete. The microporous coating stabilizes the surface fibers of the fabric (13) thereby reducing the tendency of the fibers to stick to the concrete. The pore size of the coated side of the fabric must be small enough to substantially keep all concrete particles from passing through the fabric, but sufficiently open to permit the passage of water and air.

Coffrage à béton équipé d'un revêtement à coffrage fabriqué d'un tissu dont l'étendue de la taille des pores de chacun des côtés opposés est différente. Dans une version, un revêtement microporeux, telle qu'une dispersion de micromousse de chlorure d'éthylènevinyle, est appliqué sur un côté d'un tissu perméable (13) afin de réduire de façon contrôlable la taille des pores de ce côté, pour qu'elle se situe entre 0,2 et 20 microns. Le tissu enrobé est utilisé avec un support (11) et une grille (12) de manière à composer un système de coffrage à béton (10) selon lequel le côté enrobé du tissu (13) entre directement en contact avec le béton. Le revêtement microporeux stabilise les fibres de surface du tissu (13), ce qui réduit la tendance du tissu à coller au béton. La taille des pores du côté enrobé du tissu doit être suffisamment petite pour empêcher essentiellement toutes les particules de béton de passer à travers le tissu, mais suffisamment grande pour laisser passer l'air et l'eau.
