       2 . The device as claimed in  claim 1  wherein the first sheet has a bottom edge and the second sheet has a bottom edge, and wherein the bottom edge of the first sheet is contiguous with the bottom edge of the second sheet.  
   
   
       3 . The device as claimed in  claim 1  wherein: 
 the first sheet has a top and bottom edge;    the second sheet has a top and bottom edge;    the first sheet and the second sheet comprise a first portion; and    the device further comprises a second portion comprising at least one sheet having a top edge, a bottom edge, first and second faces, and at least one drainage feature on at least one of the first and second faces wherein: 
 the drainage features are disposed to provide a water collection surface;  
 the fabric is disposed to cover at least a portion of the first and second portions; and  
 the bottom edge of the at least one sheet of the second portion is proximate to the top edges of the first sheet and the second sheet.  
   
   
   
       4 . The device as claimed in  claim 3  wherein at least one piece of fabric covers the first portion and the second portion.  
   
   
       5 . The device as claimed in  claim 3  wherein the second portion comprises a single sheet.  
   
   
       6 . The device as claimed in  claim 3  wherein the second portion comprises more than one sheet.  
   
   
       7 . The device as claimed in  claim 1  wherein the first sheet drainage features comprise dimples disposed such that the first sheet first face has depressions and the first sheet second face has corresponding protrusions, and wherein the second sheet drainage features comprise dimples disposed such that the second sheet first face has depressions and the second sheet second face has corresponding protrusions.  
   
   
       8 . The device as claimed in  claim 7  wherein the first sheet first face is disposed parallel to and adjacent to the second sheet first face.  
   
   
       9 . The device as claimed in  claim 8  wherein the first sheet first face is in contact with the second sheet first face.  
   
   
       10 . The device as claimed in  claim 8  wherein: 
 the first sheet has at least one opening formed such that water can flow from the first face to the second face;    the second sheet has at least one opening formed such that water can flow from the first face to the second face; and    the first sheet opening and the second sheet opening are aligned such that water can flow from the first sheet second face to the second sheet second face.    
   
   
       11 . The device as claimed in  claim 10  wherein the first sheet has a plurality of openings and the second sheet has a plurality of openings, and wherein more than one of the plurality of openings in the first sheet is aligned with an associated opening in the second sheet.  
   
   
       12 . The device as claimed in  claim 11  wherein the plurality of openings in the first sheet are slot shaped, and wherein the plurality of openings in the second sheet are slot shaped.  
   
   
       13 . The device as claimed in  claim 7  further comprising a separator sheet disposed between the first sheet and the second sheet.  
   
   
       14 . The device as claimed in  claim 13  wherein the first sheet second face is adjacent to a first face of the separator sheet, and wherein the second sheet second face is adjacent to a second face of the separator sheet.  
   
   
       15 . The device as claimed in  claim 14  wherein the first sheet has at least one hole provided such that water can flow from the first face of the first sheet to the second face of the first sheet, and wherein the second sheet has at least one hole provided such that water can flow from the first face of the second sheet to the second face of the second sheet.  
   
   
       16 . The device as claimed in  claim 14  wherein the first sheet has at least one expansion feature.  
   
   
       17 . The device as claimed in  claim 14  wherein the expansion feature is selected from one of a perforation and a v-shaped expansion hinge.  
   
   
       18 . The device as claimed in  claim 14  wherein the first sheet has first and second side edges and top and bottom edges, and wherein the expansion feature is disposed across the first sheet between the first edge and the second edge.  
   
   
       19 . The device as claimed in  claim 14  wherein the first sheet has first and second side edges and top and bottom edges, and wherein the expansion feature is disposed across the first sheet between the top and bottom edges.  
   
   
       20 . The device as claimed in  claim 16  wherein the second sheet has at least one expansion feature.  
   
   
       21 . A method for providing drainage, comprising: 
 providing a drainage device comprising: 
 a first sheet having first and second faces and at least one drainage feature on at least one of the first and second faces;  
 a second sheet having first and second faces and at least one drainage feature on at least one of the first and second faces, wherein the first sheet is disposed such that at least a portion of one of the first or second faces is parallel to at least a portion of one of the first or second faces of the second sheet; and  
 fabric covering at least a portion of the first sheet and the second sheet; and  
   installing the drainage device proximate to a footer of a foundation of a building, such that the drainage device provides a water transport area that directs water to a desired area.    
   
   
       22 . The method as claimed in  claim 21  wherein the step of providing a drainage device further comprises providing a drainage device wherein: 
 the first sheet has a top and bottom edge;    the second sheet has a top and bottom edge;    the first sheet and the second sheet comprise a first portion;    the device further comprises a second portion comprising at least one sheet having a top edge, a bottom edge, first and second faces, and at least one drainage feature on at least one of the first and second faces wherein: 
 the drainage features on the second portion are disposed to provide a water collection surface;  
 the fabric is disposed to cover at least a portion of the first and second portions; and  
 the bottom edge of the at least one sheet of the second portion is proximate to the top edges of the first sheet and the second sheet; and  
   wherein the step of installing the drainage device further comprises placing the second portion along the top of the footer of the foundation and placing the third portion along the wall of the foundation.    
   
   
       23 . A kit for providing drainage, comprising: 
 at least one insulation board; and    at least one drainage device comprising: 
 a first sheet having first and second faces and at least one drainage feature on at least one of the first and second faces;  
 a second sheet having first and second faces and at least one drainage feature on at least one of the first and second faces, wherein the first sheet is disposed such that at least a portion of one of the first or second faces is parallel to at least a portion of one of the first or second faces of the second sheet; and
