Where new block walls abut existing or previously erected concrete or <br />masonry walls, secure anchors to existing wall by breaking through the block <br />or chipping a recess in concrete and filling the space with grout, to prevent <br />horizontal movement. <br /> <br />G. Where walls with concrete filled voids are indicated, use regular concrete with <br />pea rock aggregate and a compressive strength of 3000 psi at twenty-eight (28) <br />days. <br /> <br />1.
