FORMLINER AND METHOD OF USE

The invention relates to formliners comprising at least two formliners configured to form a corner in curable material when the at least two formliners are assembled together. The formliners comprise a first and a second formliner. The first formliner comprises: a cell comprising a recessed portion， wherein at least a part of the recessed portion is configured contact the curable material; a boundary side extending along at least a part of the cell of the first formliner， the boundary side connected to the cell at a predetermined angle relative to the recessed portion of the cell of the first formliner， the predetermined angle corresponding to a desired angle of the corner in the curable material; and a rib extending along at least a part of the cell of the first formliner toward the boundary side， the rib of the first formliner comprising an exterior surface forming an exterior cross-sectional profile， wherein at least a portion of the exterior surface is configured to contact the curable material. The second formliner comprises: a cell comprising a recessed portion; and a rib extending along at least a part of the cell of the second formliner， the rib of the second formliner comprising an opening having a cross-sectional profile corresponding to the exterior cross-sectional profile of the rib of the first formliner with the second formliner positioned at the predetermined angle relative to the first formliner. The first formliner is configured to be assembled with the second formliner at the predetermined angle to form the corner in the curable material with the desired angle by mating the opening of the rib of the second formliner with exterior surface of the rib of the first formliner with the boundary side of the first formliner contacting the recessed portion of the cell of the second formliner along the predetermined angle relative to the recessed portion of the cell of the first formliner to minimize visible seams in the curable material.
