Installation Steps for VERSA-LOK Mosaic

Step 3 Build Additional Courses

After the base-course has been backfilled and compacted, you can begin to add subsequent courses. In a Mosaic wall, after the base-course of Standard units is laid, each additional course is laid in a series of 10-inch panels. Each panel comprises one VERSA-LOK Standard unit, one Cobble unit and two Accent units.

You can achieve a random pattern by rotating four different configurations of the four-unit panel throughout the wall. For example, alternate the position of the two Accent units with the Standard and Cobble units in each panel, and randomly mix the order of the Cobble and Standard units within the panel.

Pinning units together provides an automatic three-quarter-inch setback and adds structural stability to the wall.   

Insert two Versa-Tuff SNAP-OFF pins through the front holes in both the Standard and Cobble units so that the pins fall into the middle slots of the Standard units below. When possible, use the outside holes of the Standard units. After pinning, pull the units forward to tighten the pin connections. Then, check the alignment and level.   ,   

Next, place two Accent units on top of the Standard and Cobble units with a setback of 3/4 inch. Insert two snap-off pins through the front holes of each of the Accent units so that the pins fall into the slots of the Standard and Cobble units below.   

When possible, use the outside holes of the Accent units. Make sure the pins are fully seated in the lower-unit slots, and then snap them off. After pinning, pull the units forward to remove any looseness in the pin connections.
