Chemically Reactive Surface-Applied Waterproofing for Post-Construction Materials

Abstract

Post-construction materials, including concrete, containing water insoluble polymers are disclosed herein. The water insoluble polymers are formed beneath the surface of the post-construction material using a first composition comprising a blend of fatty acid salts and a second composition comprising alkaline earth metal halides or alkaline earth metal carbonates.

What is claimed is: 
     
         1 . A post-construction material comprising at least one surface, a void area beneath the surface, and one or more water insoluble polymers having the following formula (II) or formula (III): 
       
         
           
           
               
               
           
         
         wherein
 each X is independently an alkali metal, hydrogen, or ammonium; 
 each R 1  is independently a linear or branched C 3 -C 20  alkyl or linear or branched C 3 -C 20  alkenyl group; 
 each a is an integer from 1 to 3; 
 R 2  is a linear C 1 -C 10  alkylene group; 
 M is an alkaline earth metal; and 
 n is an integer of 2 or more; and 
 
         wherein the one or more water insoluble polymers is located within the void area. 
       
     
     
         2 . The post-construction material of  claim 1 , wherein the surface comprises no more than 5% of the water insoluble polymer based on the total amount of the water insoluble polymer. 
     
     
         3 . The post-construction material of  claim 1 , wherein at least one of the one or more water insoluble polymers contains repeating units having at least two different R 1  groups. 
     
     
         4 . The post-construction material of  claim 1 , wherein the post-construction material having the water insoluble polymer has less than 1% absorption of water.
