Abstract
A system including a polymeric sheet. The polymeric sheet comprises a base sheet having a first surface and a second surface opposite the first surface and a multiplicity of spaced rails projecting from the first surface of the base sheet. The rails comprise a stem portion attached to and substantially upright from the first surface of the base sheet and a top portion on the distal end of the stem opposite the base sheet. The top portion comprises a first surface opposite the base sheet and a second surface facing the first surface of the base sheet. Additionally, the rails have a length greater than the width of the stems. The first surface of the base sheet, the second surface of the top portion and the surface of the stem defines a cavity with walls, and an adhesive coated on at least a portion of the cavity wall.
