A liquid-controlling surface, comprising a formation comprising a plurality of individual open topped, closed bottomed cells for containing liquid, each of the cells having a cell wall integral with the closed bottom and defining a well; a plurality of distribution channels extending between adjacent cells and being position 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; and a perimeter wall surrounding the cells. The perimeter wall having a height higher than the distribution channels to prevent liquid from leaking from the cells to an area outside the perimeter, and where the formation and perimeter wall comprise rubber.

The liquid controlling surface as claimed in claim 1, wherein said rubber is moulded rubber. 3. The liquid controlling surface as claimed in claim 1, wherein each distribution channel is configured so as to inhibit an object resting on top of the internal cell wall from contacting liquid in the cells or the distribution channel. 4. The liquid controlling surface as claimed in claim 1, wherein at least some of said cell walls are dimensioned and arranged to prevent an object from contacting said liquid in said cells or the distribution channel. 5. The liquid controlling surface as claimed in claim 4, wherein said object is a persons foot or vehicle tire. 6. The liquid controlling surface as claimed in claim 1, wherein at least some of said cell walls are adapted to support a load. 7. The liquid controlling surface as claimed in claim 6, wherein said load is a person or a vehicle. 8. The liquid controlling surface as claimed in claim 1, wherein the cell walls are tapered upwardly to reduce a contact area between the surface and an object resting thereon and to promote drainage of liquids therefrom. 9. The liquid controlling surface as claimed in claim 8, where the cell walls are tapered substantially to a point at a top edge thereof. 10. The liquid controlling surface or surface application as claimed in claim 8, wherein the tapered cell walls have non-pointed tops. 11. The liquid controlling surface as claimed in claim 1, wherein the distribution channels comprise arcuate depressions extending across the cell walls. 12. The liquid controlling surface as claimed in claim 1, wherein the formation and the perimeter wall are a unitary construction. 13. The liquid controlling surface as claimed in claim 1, wherein the surface further comprises at least one reservoir channel and a reservoir positioned adjacent said formation and configured to receive liquid from the reservoir channels. 14. The liquid controlling surface as claimed in claim 13, wherein said perimeter wall surrounds said formation and reservoir. 15. The liquid controlling surface as claimed in claim 14, wherein the surface further includes a drain positioned to drain liquid from the reservoir. 16. The liquid controlling surface as claimed in claim 13, wherein the reservoir contains an absorbent material for absorbing liquid moving into the reservoir. 17. The liquid controlling surface as claimed in claim 13, wherein the surface further comprises a removable reservoir cover. 18. The liquid controlling surface as claimed in claim 1, wherein the formation is generally rectangular. 19. The liquid controlling surface as claimed in claim 18, wherein the cells are generally rectangular in plan view. 20. The liquid controlling surface as claimed in claim 1, wherein the cells are generally rectangular in plan view. 21. The liquid controlling surface as claimed in claim 1, wherein said cell comprises a well for holding liquid, the distribution channels being positioned at a top of the well, the cell wall being sized and shaped to surround the well. 22. The liquid controlling surface as claimed in claim 1, wherein the cells and cell walls are sized and shaped so as to provide contact areas that are generally circular in plan view. 23. The liquid controlling surface as claimed in claim 22, wherein the contact areas bulge outward to encourage draining of liquid from the contact area to cells. 24. The liquid controlling surface as claimed in claim 1, wherein the cells and cell walls are sized and shaped so as to provide contact areas that are generally octagonal. 25. The liquid controlling surface as claimed in claim 1, wherein the surface includes a drain positioned to drain liquid from one or more cells. 26. The liquid controlling surface as claimed in claim 1, wherein the surface comprises a liquid-flow-away section and a liquid retaining section, and wherein an average well depth in the liquid-flow-away section is less than an average well depth in the liquid retaining section to cause liquid to move from the liquid-flow-away section to the liquid retaining section. 27. The liquid controlling surface as claimed in claim 1, wherein the surface comprises a liquid-flow-away section and a liquid retaining section, and wherein an average cell height, above a floor, in the liquid-flow-away section, is greater than an average cell height, above the floor, in the liquid retaining section, to cause liquid to move from the liquid-flow-away section to the liquid retaining section. 28. The liquid controlling surface as claimed in claim 1, wherein the surface comprises a plurality of surface modules connected together. 29. The liquid controlling surface as claimed in claim 1, wherein said perimeter wall is free of distribution channels. 30. The liquid controlling surface as claimed in claim 1, wherein the surface is a mat.
