Surface for controlling liquids
Abstract:
A liquid controlling surface, comprising a formation comprising a plurality of individual open topped, closed bottomed cells for containing liquid with each of the cells having a cell wall integral with the closed bottom and defining a well. Each of the cell walls have a top edge. The surface also includes a plurality of distribution channels extending between adjacent cells and being positioned on the cell wall at a height to permit liquid to drain to the adjacent cell when a cell liquid level exceeds a predetermined limit and to permit liquid to be retained in the well up to the limit. At least some of the cell walls are sized and shaped to define contact areas at the top edges to support an object above the limit.
