What is claimed is:  
     
         1 . A method to repair a damaged portion of a PCC sidewalk, the method comprising the steps of: 
 (a) removing a portion of the PCC sidewalk that is damaged and to be repaired by replacement, the removing of the portion of the PCC sidewalk substantially forming a volume; and    (b) installing into the volume at least one piece of solid, yet flexible material, the piece of material fitted to fill the volume and restore the damaged portion of the PCC sidewalk to substantially an original height.    
     
     
         2 . The method according to  claim 1 , further including the step of tamping and substantially leveling a bottom surface area established by the volume before installing the piece of material.  
     
     
         3 . The method according to  claim 1 , wherein the piece of material is provided having a fixed uniform thickness and is mat-like in shape.  
     
     
         4 . The method according to  claim 3 , wherein a filling means may be placed over the bottom surface area, for leveling purposes, prior to installation of the piece of material, thereby resulting in filling the volume in part by the filling means and in part by the piece of material.  
     
     
         5 . The method according to  claim 1 , wherein the piece of material is provided and formed by a rubberized composite mixture that may be poured into and fill the volume to restore the sidewalk to substantially an original height.  
     
     
         6 . The method according to  claim 1 , wherein the piece of material is provided in a bright color to indicate and warn nearby persons that a portion of the sidewalk, which now contains the piece of material thereat, may not be substantially or entirely flat.  
     
     
         7 . A method wherein a damaged portion of PCC sidewalk is repaired by replacement, the method comprising the steps of: 
 (a) establishing a volume by removing the damaged portion of the sidewalk to be repaired by replacement;    (b) at least one of tamping and leveling a bottom surface area formed by the volume; and    (c) installing within the volume at least one piece of dense rubberized material sized to have a snug fit within the volume, and restore an area that included the damaged portion of sidewalk to substantially an original height.    
     
     
         8 . The method according to  claim 7 , wherein the dense rubberized material is provided as a thick fixed thickness sheet material that may be cut and trimmed to provide the snug fit when installed within the volume.  
     
     
         9 . The method according to  claim 8 , wherein at least one side wall of the dense rubberized material is fixed to at least one vertical side wall portion of an adjacent portion of PCC sidewalk with the side walls of the dense rubberized material and the vertical side walls of adjacent portions of the sidewalk abutting each other.  
     
     
         10 . The method according to  claim 9 , wherein at least one side wall of the dense rubberized material and at least one vertical side wall of the PCC sidewalk that are abutting are fixed and joined by employing glue means therebetween.
