the material will be capable of meeting applicable requirements at the time of mixing. Masonry materials shall be stored
so that at the time of use the materials are clean and structurally suitable for the intended use. Concrete masonry units
shall not be wetted unless otherwise approved.
2. Reinforcement shall be placed prior to inspection and grouting, with vertical reinforcement located in the cell as
indicated in Part—III. All reinforcement shall be free from loose rust and other coatings that would inhibit reinforcing bond,
and shall be secured against displacement prior to the placement of concrete or grouting by wire positioners or other
suitable devices at intervals not exceeding 200 bar diameters nor 10 feet. Grout Stop shall be completely omitted at
all cells containing vertical reinforcement.
3. Footings shall be level. If ground slopes, footings shall be stepped so that the top and bottom of the footing are level. All
excavations shall be clean and contain no loose earth or other foreign materials.
4. The method of measuring material for mortar and grout shall be such that proportions of the materials can be controlled.
The mortar shall be sufficiently plastic and units shall be placed with sufficient pressure to extrude mortar from the joint
and produce a tight joint. Mortar or grout wich has hardened or stiffened due to hydration of the cement shall not be
used, but under no case shall mortar be used two and one—half hours(2-1\2 hrs), nor grout used one and one—half
hours(1-1 \2 hrs), after the initial mixing water has beed added to the dry ingredient at the job site.
5. The initial bed joint thickness shall not be less than 1/4 inch nor more than 1 inch; subsequent bed joints shall be not
less than 1/4 inch nor more than 5/8 inch in thickness. All head and bed joints shall be filled solidly with mortar for a
distance in from the face of the unit not less than the thickness of the shell, (if required, head joints may be omitted
in the first course for weep holes.)

7. Prior to grouting, the grout space shall have vertical continuity and shall be clean so that all spaces to be filled with grout
do not contain mortar projections greater than 1/2 inch, mortar droppings or other foreign material. All cells and spaces
containing reinforcing bars shall be filled solidly with grout.
8. If any portion of the wall is to extend across a property line, written (notarized) permision from the adjacent property
owner is required.
9. Building Department Inspection shall be following steps: PREPARE[
1st — foundation trench with secured reinforcing steel.
2nd — Block wall with reinforcing steel in place BEFORE GROUT.
3rd — Gouted wall and drainage system. (NO BACKFILL is allowed before drain system inspection
SEE NOTE #12). TEN
4th — Backfill and final.
