<p>Embodiments of the present invention allow for the manufacture of a number of drainage channels of different heights, widths, thicknesses, shapes, and slopes from only one mold or a greatly-reduced number of molds. In one embodiment, the drainage channel mold has an interior mold and an exterior mold. The exterior mold has two opposing sidewalls that can be placed at different distances apart from one another to vary the overall width of the drainage channel. The sidewalls can be independent of each other or they can be coupled to each other yet still allowed to be positioned at different distances apart. In one embodiment, the sidewalls are hingedly coupled to a base support mechanism. The mold also contains mold spacers that can be located between the interior mold and the exterior mold sidewalls to create different heights, widths, shapes, and slopes in the drainage channel walls formed by the adjustable mold.</p> |
