In fact, the basic construction procedures that are used for wall construction also apply for <br /> installing Anchor Diamond step units. <br /> STEP 1 �'�� � <br /> Using both standard and step units, establish the base y ` <br /> course according to the wall design, Use normal con- <br /> struction procedures (figure 1).
