<br />INDICATED IN NCMA TEK 8-2A APPLICABLE TO TYPE OF STAIN
<br />ON EXPOSED SURFACES.
<br />3.11 MASONRY WASTE DISPOSAL
<br />A. WASTE DISPOSAL AS FILL MATERIAL: DISPOSE OF CLEAN MASONRY
<br />WASTE, INCLUDING EXCESS OR SOIL -CONTAMINATED SAND, WASTE
<br />MORTAR, AND BROKEN MASONRY UNITS, BY CRUSHING AND MIXING
<br />WITH FILL MATERIAL AS FILL IS PLACED.
<br />1. DO NOT DISPOSE OF MASONRY WASTE AS FILL WITHIN 18
<br />INCHES (450 MM) OF FINISHED GRADE.
<br />2. REMOVE EXCESS CLEAN MASONRY WASTE THAT CANNOT BE
<br />USED AS FILL, AS DESCRIBED ABOVE, AND OTHER MASONRY
<br />WASTE, AND LEGALLY DISPOSE OF OFF OWNER'S PROPERTY.
