摘要:
Concrete forms utilizing a laminated concrete form liner including a porous fabric laminated to a drainage scrim. The laminated form liner is untensioned and used in combination with a support to form a concrete casting system wherein the porous fabric side of the laminated form liner is placed directly in contact with the concrete. The drainage scrim enhances the ability of the form liner to remove excess water from the surface of the concrete.
