A procedure known as pointing may be required
after jointing. Pointing is the process of inserting

in the second horizontal mortar joint from the top of
the wall under the cores that will contain the bolts
(figure 8-18, view 1). Use anchor bolts 1/2 inch in
diameter and 18 inches long. Space them not more

course, insert the bolts into the cores of the top two
courses and till the cores with concrete or mortar.
The metal lath underneath holds the concrete or
mortar filling in place. The threaded end of the bolt
should extend above the top of the wall (view 2).
