PART 3  -  EXECUTION

    INSTALLATION GUIDELINES
		
    Fill all open cells and voids in hollow concrete masonry 
    walls where shown on drawings.  The foam insulation shall 
    be pressure injected through a series of  5/8" to 7/8" 
    holes drilled into every vertical column of block cells 
    (every 8" on center) beginning at an approximate height of 
    four (4) feet from finished floor level.  Repeat this 
    procedure at an approximate height of  ten (10) feet above 
    the first horizontal row of  holes (or as needed) until 
    the void is completely filled.  Patch holes with mortar 
    and score to resemble existing surface.
