Aboveground waterproofing boards, systems, and methods

Abstract

Systems, methods, and boards for insulating building foundations are provided. The boards can be fiberglass, and the boards may have a pre-applied scrim. At least one coating can be provided on at least one face of the insulation boards. The boards can be applied to a portion of the building foundation above the grade line.

1 . A board, comprising: 
 an insulation board substrate having a first surface and a second surface; and    a planar scrim having an open structure secured to at least a portion of said insulation board substrate, wherein said scrim is secured to said insulation board by placing said scrim in contact with a fiberglass woolpack and curing said woolpack such that said insulation board substrate with said scrim secured to said first surface is formed.    
   
   
       2 . The board as claimed in  claim 1  wherein said scrim is formed from a material having between about 3×3 to about 30×30 threads per square inch.  
   
   
       3 . The board as claimed in  claim 2  wherein said scrim has about 10×10 threads per square inch.  
   
   
       4 . The board as claimed in  claim 1  wherein at least one edge of said insulation board substrate is beveled.  
   
   
       5 . The board as claimed in  claim 1  wherein said scrim is made from a material selected from at least one of a woven, non-woven, and polymeric material.  
   
   
       6 . The board as claimed in  claim 1  wherein said scrim comprises a glass scrim.  
   
   
       7 . The board as claimed in  claim 1  wherein said scrim is secured to said insulation board substrate without an adhesive.  
   
   
       8 . The board as claimed in  claim 1  wherein said board has a top edge, a bottom edge, and first and second side edges, and wherein said scrim is applied such that edges of said scrim are proximate to said top, bottom, and first and second side edges of said insulation board substrate.  
   
   
       9 . The board as claimed in  claim 1  wherein said scrim is disposed such that said scrim enhances application of a coating to said insulation board substrate.  
   
   
       10 . The board as claimed in  claim 9  wherein said scrim is disposed to enhance application of an elastomeric coating.  
   
   
       11 . The board as claimed in  claim 1  wherein said scrim is disposed such that said scrim provides reinforcement to a coating applied to said insulation board substrate.  
   
   
       12 . A method for producing a board, comprising: 
 providing a planar scrim having an open structure such that said planar scrim is disposed on at least a portion of a first surface of a fiberglass woolpack; and    subsequently curing said fiberglass woolpack such that an insulation board substrate having said scrim secured to at least a portion of a first surface of said insulation board substrate is formed.    
   
   
       13 . The method as claimed in  claim 12  wherein said step of subsequently curing comprises curing said woolpack at a temperature between about 450° F. to about 500° F.  
   
   
       14 . The method as claimed in  claim 12  wherein said step of subsequently curing further comprises compressing said woolpack during said step of subsequently curing.  
   
   
       15 . The method as claimed in  claim 12  wherein said scrim is formed from a material having between about 3×3 threads to about 30×30 threads per square inch.  
   
   
       16 . The method as claimed in  claim 15  wherein said scrim has about 10×10 threads per square inch.  
   
   
       17 . The method as claimed in  claim 12  wherein the step of providing a scrim comprises providing a scrim having a top edge, bottom edge, and first and second edges on a woolpack having a top edge, bottom edge, and first and second edges, and wherein said scrim is disposed such that the edges of said scrim are proximate to the edges of the woolpack.  
   
   
       18 . The method as claimed in  claim 12  wherein said step of providing a scrim further comprises providing a scrim having a structure through which an elastomeric coating can flow such that said elastomeric coating can contact said insulation board substrate.
