Abstract

A drainage component having a continuous, extruded mat having an upper face and a lower face. The mat includes a plurality of patterned three-dimensional structures, each structure spaced from all adjacent structures, and the plurality of patterned three-dimensional structures are provided in a plurality of linear rows or columns in a first direction.

Claims (26)

1. A drainage component, comprising:

a continuous, extruded mat having an upper face and a lower face,

wherein the mat comprises randomly convoluted polymeric filaments, the randomly convoluted polymeric filaments being self-bonded or fused at random points of intersection and being shaped into a plurality of patterned three-dimensional structures, each of the plurality of patterned three-dimensional structures spaced, including at a base thereof, from all adjacent patterned three-dimensional structures, including at respective bases thereof, so that a spacer portion of the mat including a network of randomly convoluted polymeric filaments of a density different than a density of a network of the randomly convoluted polymeric filaments of the plurality of patterned three-dimensional structures is exposed on all sides of each of the plurality of patterned three-dimensional structures, and

wherein the plurality of patterned three-dimensional structures are provided in a plurality of linear rows or columns in a first direction, but three-dimensional structures of adjacent ones of the plurality of linear rows or columns in the first direction are offset from each other in a second direction perpendicular to the first direction.

2. The drainage component according to claim 1 , further comprising a fabric sheet adhered to at least one of the lower face and the upper face of the mat.

3. The drainage component according to claim 1 , wherein each of the plurality of patterned three-dimensional structures have an indentation at a substantially center portion of the respective patterned three-dimensional structure, the indentation protruding from the upper face of the mat toward the lower face of the mat.

4. The drainage component according to claim 3 , further comprising a fabric sheet adhered to at least one of the lower face and the upper face of the mat.

5. The drainage component according to claim 1 , wherein each of the plurality of patterned three-dimensional structures are hexagonal.

6. The drainage component according to claim 1 , wherein the network of the randomly convoluted polymeric filaments of the spacer portion has a higher density than the network of the randomly convoluted polymeric filaments of the patterned three-dimensional structures.

7. The drainage component according to claim 2 , wherein the fabric sheet comprises a filter fabric.

8. The drainage component according to claim 2 , wherein the fabric sheet comprises a permeable radiant barrier.

9. The drainage component according to claim 4 , wherein the filter fabric is bonded to the mat at each of the indentations.

10. The drainage component according to claim 9 , wherein the filter fabric is bonded to the mat only at each of the indentations.

11. A building structure, comprising:

a member;

a drainage component; and

a composition,

wherein the drainage component comprises a continuous, extruded mat having an upper face and a lower face, the mat comprising randomly convoluted polymeric filaments, the randomly convoluted polymeric filaments being self-bonded or fused at random points of intersection and being shaped into a plurality of patterned three-dimensional structures, each of the plurality of patterned three-dimensional structures spaced, including at a base thereof, from all adjacent patterned three-dimensional structures, including at respective bases thereof, so that a spacer portion of the mat including a network of randomly convoluted polymeric filaments of a density different than a density of a network of the randomly convoluted polymeric filaments of the plurality of patterned three-dimensional structures is exposed on all sides of each of the plurality of patterned three-dimensional structures, and the plurality of patterned three-dimensional structures being provided in a plurality of linear rows or columns in a first direction, but three-dimensional structures of adjacent ones of the plurality of linear rows or columns in the first direction are offset from each other in a second direction perpendicular to the first direction.

12. The building structure according to claim 11 , wherein the drainage component further comprises a fabric sheet adhered to at least one of the lower face and the upper face of the mat.

13. The building structure according to claim 11 , wherein the drainage component is provided between the member and the composition.

14. The building structure according to claim 11 , wherein the composition comprises cement.

15. The building structure according to claim 12 , wherein the drainage component is oriented so that the fabric sheet contacts the composition, and the mat contacts the member.

16. The building structure according to claim 11 , wherein the member is an inner sheathing member of a sidewall of a building.

17. The building structure according to claim 12 , wherein the fabric sheet comprises a filter fabric.

18. The building structure according to claim 12 , wherein the fabric sheet comprises a permeable radiant barrier.

19. The building structure according to claim 11 , wherein each of the plurality of patterned three-dimensional structures have an indentation at a substantially center portion of the respective patterned three-dimensional structure, the indentation protruding from the upper face of the mat toward the lower face of the mat.
