A water-impervious, non-biodegradable, unitary drainage device for conveying subsoil seepage to suitable disposal areas. The invention features a “sandwich” construction consisting of a planar top and base sheets, set apart by a matrix of supports, disposed between and integrally joined to the sheets. The matrix is a row-column array of frusto-geometrically shaped elements; in an alternate embodiment, this sheet-separating array is a series of parallel row, or columnar, partitions. Partitions, in emulation of discrete posts, contain structural separations, at selected locations, in order to relinquish the inherent rigidity of the unitary construction. The parallel top and bottom sheets are fixed permanently to, or formed integrally with, posts or partitions, rendering the nominal construction quite rigid. Making selective through-cuts in the top sheet imparts, to the invention, a one- or two-dimensional flexibility that facilitates its use under concrete floors, installation on vertical surfaces and as a footing form-drain.
A seepage drain device for conveying water, passing thereinto, from a first locale to another locale and comprising:
A monolithic drainage device for use in sub-floor and subterranean situations and comprising a non-biodegradable, layered device featuring a continuous, planar bottom layer of a flexible material and a planar top layer that is rendered non-continuous by at least one linear slot cut therethrough, the top layer and the bottom layer disposed in a set apart, parallel registry by, and integrally joined with, a row-column matrix of discrete support elements.
A unitary drainage means for conveying fluids passing thereinto from a first locale to another locale and comprising:
