Abstract
Abstract A water-impervious, non-biodegradable, unitary drainage device with multi-directional rollup capability. The invention features a monolithic “sandwich” construction consisting of planar top and base sheets, set apart by an array of supports that are disposed between and integrally joined to the sheets. Selective and off-set through-cuts, in the top and bottom sheets, impart to the invention the multi-dimensional rollup capability. Rods, optionally hollow, are used as splines to connect two or more of the devices, so that their internal drain channels are in an efficient confluent alignment.
