Installation Steps for VERSA-LOK Standard, Cobble and Accent

Level the units front to back and side to side using a 4-foot hand level. A shorter torpedo level may be easier for leveling front to back. You can tap high points with a rubber mallet or hand tamper to achieve level.     |   

Take the time to get your base-course level, because even minor unevenness in the base-course will be amplified and difficult to correct after several courses have been installed.  After the base-course is completed, replace and compact the soil in front of and behind the units. The backfill behind and in front of all embedded units should be soil.   

Step 3 Build Additional Courses

After the base-course has been backfilled and compacted, you can begin to add subsequent courses. The relationship of vertical joints from one course to the next is called bond. VERSA-LOK’s unique hole-to-slot pinning system allows these joints to vary or wander in relation to other joints throughout the wall. However, units should generally overlap adjacent lower-course units by at least 4 inches to enhance structural stability. Regardless of the bond of your wall, be sure to keep all vertical face joints tight.   

Versa-Tuff Pins inserted through the front holes of the upper-course units into the receiving slots in the lower-course units provide an automatic three-quarter inch setback and add structural stability.   

Before you add each course, sweep off the tops of the installed units to remove any debris that may interfere with the next course. As you position the units, slide them into place. This will help remove any imperfections and debris from the surfaces of adjoining units and ensure a tight fit.

Place and pin the units set back three-quarter inch behind the face of the base-course units. There are four front holes in each unit, but only two are used. When possible, use the two outside holes.
