A construct for use in a wall structure, comprising:
- a lath member;
- and
- a water channel material having a front side and a back side with a width defined therebetween, the width of the water channel material including therein a structure that yields a path for water passing through the width of the water channel material under the influence of gravity when the water channel material is in use, wherein the water channel material comprises a plastic sheet defining a plane and having a front side and a back side, wherein the water channel material has corrugations, projections or a combination thereof extending from the plane of the water channel material.
A construct for use in a wall structure, comprising:
- a lath member comprised of a first plurality of filamentous plastic elements arranged parallel to one another that are joined by a second plurality of filamentous plastic elements that cross therebetween thereby forming a matrix, the lath member having a front side and a back side;
- and
- a water channel material comprising a sheet of plastic having corrugations, projections or a combination thereof extending from a plane of the water channel material, the water channel material having a front side and a back side, wherein the front side of the water channel material is coupled to the back side of the lath member.
