Abstract

A method and composition for waterproofing a substrate herein is described which includes applying a coating composition to a surface of the structural unit. The coating composition includes a) an organic solvent, b) a hydrocarbon resin and c) a styrene polymer, having a styrene content of about 60 wt % or greater, selected from the group consisting of a copolymer having styrene and diene monomer units, a copolymer having styrene and olefin monomer units, a polymer having styrene monomer units and mixtures thereof.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A waterproofing composition, comprising: 
 about 33 phr to about 250 phr of an organic solvent;    about 10 phr to about 50 phr of a polyindene; and    about 50 phr to about 90 phr of a styrene polymer, having a styrene content of about 60 wt % or greater, selected from the group consisting of a copolymer having styrene and diene monomer units, a styrene homopolymer and mixtures thereof.    
     
     
         2 . The waterproofing composition of  claim 1 , wherein the diene monomer units include butadiene, isoprene and mixtures thereof.  
     
     
         3 . The waterproofing composition of  claim 1 , wherein the styrene polymer has a styrene content of 85 wt. % or greater.  
     
     
         4 . A waterproofing composition, comprising: 
 about 50 to about 150 phr of an organic solvent;    about 30 phr to about 50 phr of a polyindene;    about 50 phr to about 70 phr of a styrene polymer, having a styrene content of about 60 wt % or greater, selected from the group consisting of a copolymer having styrene and diene monomer units, a styrene homopolymer and mixtures thereof.    
     
     
         5 . The waterproofing composition of  claim 4 , wherein the diene monomer units include butadiene, isoprene and mixtures thereof.  
     
     
         6 . The waterproofing composition of  claim 4 , wherein the styrene polymer has a styrene content of 85 wt. % or greater.  
     
     
         7 . The waterproofing composition of  claim 4 , further comprising about 20 phr to about 600 phr of a filler
