Solid grouted walls are relatively simple because all cells of the masonry are filled with grout. We fill all vertical cells and horizontal bond beams with grout. All voids are filled with grout. There is no need to exclude certain members or specified areas that should not be grouted. Solid grouting is simple. Grout everything.
Many contractors will suggest to solid grout the walls in lieu of leaving voids or small areas un-grouted. In California if grouting is to be closer than 32" (813 mm) on centers say at 16", 24" (406 mm, 610 mm) on centers, the contractor will say "let me grout it solid without any extra charges". His concern is that it will cost more in labor to block off cells than to provide the additional grout. How do you partially grout a wall? How do we partially grout walls and members that require grouting at 32" (813 mm) on center on greater say 40", 48" (1016 mm, 1219 mm)?
This is basically the crux of this article. The basic technique is to seal off the cells both vertical and horizontal that are not to be grouted. For vertical cells, the mortar is placed on either side of the cell to be grouted so that when that cell is grouted there will be
