Abstract: A non-biodegradable, unitary drainage device of flexible character. The invention features a monolithic, skeletal construct consisting of stacked, planar or poly-formational arrays of quasi-tubular, tube or rod supports, termed “stand-off” elements. Actual positioning of the supports in their arrays is varied, with parallel interleaving, cross-linking and intertwining of supports to acquire varying degrees of strength and flexibility. Depending on specific function to be performed, optional covering sheet(s) of differing materials, that provide either particulate filtering or fluid impermeability (sealing), may be used with the various matrices. A different modality is also shown, wherein rods are mixed with tubules or perforated tubes to acquire the analogous structures, for use with great overburdens of stone or soil.

Abstract: A non-biodegradable, unitary drainage device of highly flexible character. The invention features a monolithic, sandwich construct consisting of membranous, planar top and, optional-use, bottom sheets which form a wrap/envelope or covering on a planar array of quasi-tubular supports or “stand-off ”elements. Actual positioning of the supports in their planar array is varied, with parallel-interleaving, cross-lining and intertwining of supports, of either or both embodiments, being done to acquire varying degrees of strength and flexibility. Depending on specific function to be performed, the covering sheet(s) may be of differing materials, for either particulate filtering or fluid impermeability (sealing). A connection adjunct is provided that allows direct fluid communication from support(s) of one such monolith to another.

Abstract: A subterranean drain system that includes hollow dimples that extend perpendicularly from a drain board. The system also includes a connector that typically allows multiple boards to be connected together, or to connect to other elements.

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 which are set apart by an array of supports. The supports 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 connectors to join two or more of the devices, so that their internal drain channels are in an efficient, confluent alignment. A filtering adjunct is provided that assures exclusion of particulate in soil emplacements, yet obviates the need for aggregate. The fabric used for filtration is prevented from occluding, by impaction, most drainage apertures; it being fixed to a permanent stand-off network of supportive projections from the top or bottom sheets.

Abstract: A dimpled drain board is disclosed which includes a dimpled drain board comprising a planar base having a first surface and second surface and a multiplicity of hollow dimples arranged in a repeating pattern extending perpendicularly from said first surface of said base. A connector operatively engages to one or more of said hollow dimples of said dimpled drain board and is used to connect devices such as a pipe, footing drain, sheet protector, perforated board, finish board, and insulation board, operatively engaged to one of more of said hollow dimples by said connector.

Abstract: 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.

Abstract: A form for use with hardenable, flowable material such as concrete, wherein the form is flexible along a first axis and rigid along a second axis. The form may further include perforations in one side of the form such that when the form is left in place the form acts as a drain.

Abstract: A concrete slab and wall spacer with water and radon removal elements. The invention includes a cross-sectionally, L-shaped elongate strip of semi-rigid, nonbiodegradable material. At least halfway up the entire elongate vertical leg of the L-shape is a horizontally disposed projection which is integral with the strip. The spacer projection is placed against a wall, the L base resting on a portion of the footing subtended by the wall in a conventional spacer usage. The underside of the base of the L is generally relieved in order to allow transmigration of water and gaseous substances. Several applications for the strip are disclosed, one being the sealing of the shelf to the abutting wall with placement of a gas impermeable membrane in an overlapping arrangement with the L base so as to form, relative to the strip and the abutted wall, an upper fluid region and a lower gas region.

At least halfway up the entire elongate vertical leg of the L-shape may be a horizontally disposed projection which is integral with the strip. The spacer projection is placed against a wall, the L base resting on a portion of the footing subtended by the wall in a conventional spacer usage. An spacer may be provided for additional support of the L-shaped strip. This spacer is easily removable after the floating slab has set, or the spacer may be left in place for use as a decorative molding. Several applications for the strip, are disclosed, one being the sealing of the shelf to the abutting wall with placement of a gas impermeable membrane in an overlapping arrangement with the L base so as to form, relative to the strip and the abutted wall, an upper fluid region and a lower gas region.

Abstract: A permanent form-drain network adapted for radon remediation. A permanently installed form-drain system is partially piecewise modified and adapted to collect and remove radon gas from sub-slab, as well as basement and similar near-subterranean, portions of building. The partial piecewise modification of an existing form-drain includes adapting existing connector elements of the form-drain with vent tubes and differently molded pieces such as offset transition conduits and "T" shaped divergent conduits. The method for installing the invention conceives of the use of a radon accretion zone gas barrier made of an impermeable membrane.

Abstract: A permanently-installed form-drain (10) including hollow, foraminous planks (12) and connectors (16,18) for joining two or more of the planks in a continuously arranged concrete barrier. The instant improvements include an adapter (20/21), which serves as a straight connector, grooved plank (19) with interlocking stake (13/14), integral connector-stake and adapter-stake device (16/14, 20/14) and a tri-functional, generally rigid bracket and bracket-stake (22 and 22/22x) element, used to space and restrain/constrain the planks and/or to hold (support) reinforcement bars.

Abstract: A concrete footing/foundation retainment co-features integral (unitary) drainage means. Two preferred embodiments present, first, a rigid, environmentally nondegradable and free-standable footing/foundation concrete retainment form similar to an ordinary plank but featuring a hollow core which communicates through a multiplicity of foramens (holes) with only one face of the plank, the other being smooth and generally unrelieved in character. The second preferred embodiment presents a similar plank bearing a colinear, foraminous conduit adjacent one margin of the plank and permanently joined with the plank member. Thus, in the second embodiment, only one face is essentially smooth and unrelieved, while the other, in cross-section, appears bulbous. The bulbous feature may take on any conceivable geometric definition ranging from a semi-tubular to a rectangular conduit shape.
