The water drainage layer serves to remove water that might otherwise build up between the lath and wall structure. ## Claims ### Claim 1 A construct for use in supporting a wall structure, comprising: a lath member, a water channel material having a front side and a back side defining a width therebetween, said width being generally filled in cross-section with elements that separately or as a unitary whole span said width so as to define a circuitous path for water passing through said width from a top to a bottom thereof, a plurality of spacers between said lath member and said water channel material, said lath member, spacers and water channel material being provided as a unitary whole. ### Claim 2 (depends on 1) The construct of claim 1, wherein said water channel material is a mat of non-absorbent fibrous material. ### Claim 3 (depends on 2) The construct of claim 2, further including a scrim layer between said lath member and said water channel material. ### Claim 4 (depends on 3) The construct of claim 3, wherein said scrim layer is adhered to said water channel material. ### Claim 5 (depends on 1) The construct of claim 1, wherein said lath member is a plastic material having substantially rigid thin diameter filaments extending generally parallel to one another joined together by crossparts into a matrix, said matrix further being formed with an undulating surface shape of peaks and valleys. ### Claim 6 (depends on 2) The construct of claim 2, wherein said spacers are a self-sealing material. ### Claim 7 (depends on 1) The construct of claim 1, wherein said unitary whole is a roll stock. ### Claim 8 A construct for use in supporting a wall structure, comprising: a lath member, a water channel material having a front side and a back side with a width defined therebetween, said water channel material width including therein a structure which yields a circuitous path for water passing through said width under the influence of gravity when said water channel material is in use, said water channel material being located inboard to a wall structure relative to said lath member which is located more outboard to said wall structure. ### Claim 9 (depends on 8) The construct of claim 8, wherein said water channel member and said lath member are joined together as an integrated whole as a stock material prior to installation in said wall structure. ### Claim 10 (depends on 9) The construct of claim 9, further including a plurality of spacers between said lath member and said water channel material. ### Claim 11 (depends on 10) The construct of claim 10, wherein said spacers are made of a material through which a fastener is receivable in a manner whereby said spacer embraces said fastener in a water sealing manner. ### Claim 12 (depends on 11) The construct of claim 11, wherein said spacers are provided on a scrim member and are formed integral therewith over a face of said scrim, and said scrim is joined with said lath member and said water channel member as an integrated whole as a stock material. ### Claim 13 (depends on 8) The construct of claim 8, further including a scrim member having spacers provided on said scrim member which are formed integral therewith over a face of said scrim, and said scrim is located inboard relative to said lath member. ### Claim 14 A lath for use in building, comprising filament-type material which is formed into a non-woven mat yielding interstices within which an initially viscous building material is receivable to form a facing with said mat when said building material is solidified. ### Claim 15 (depends on 14) The lath of claim 14, wherein said filament-type material is a plastic material. ### Claim 16 A method for building a wall structure comprising; providing a lath comprising filament-type material which is formed into a non-woven mat yielding interstices within which an initially viscous building material is receivable; affixing said lath in a generally vertical orientation as part of a wall; applying said initially viscous building material to said lath to form a facing with said mat when said building material is solidified. ### Claim 17 (depends on 16) The method of claim 16, wherein said filament-type material is a plastic material. ### Claim 18 A method for building a wall structure, comprising emplacing an interior wall shell structure: providing a water channel material having a front side and a back side with a width defined therebetween, said water channel material width including therein a structure which yields a circuitous path for water passing through said width under the influence of gravity when said water channel material is in use; locating said water channel material outboard of said interior wall shell structure; providing a lath member; locating said lath member outboard of said water channel material. ### Claim 19 (depends on 18) The method of claim 18. further including placing spacers between said lath member and said water channel material. ### Claim 20 (depends on 19) The method of claim 19, wherein said water channel material and said spacers are provided as an integrated whole. ### Claim 21 (depends on 19) The method of claim 19, wherein said water channel material and said spacers and said lath are provided as an integrated whole.
