ABSTRACT:
A flexible reinforced concrete form line is provided which includes a plurality of elongated cuttable strips which are sized and embedded within the textured surface of the flexible form liner. The cross-sectional shape of the strips is substantially the same as the cross-sectional shape of the textured surface of the liner except smaller so that the thickness of the elastomeric material making up the liner is substantially constant throughout resulting in consistent expansion and contraction of the liner during setting of the concrete. The strips can be suspended within the liner during the elastomeric molding process or the strips can be directly attached to the plywood form backing sheet prior to the molding process. The total quantity of elastomeric material making up the liner can be greatly reduced which, in turn, reduces the weight of the overall form.
