Installing on Existing Patios or Pavement

If you will be building in an area that does not have an existing patio or pavement, see How-to Sheet #120 Building Wall Panels and How-to Sheet #220 Building Posts for instructions on building the base. When bulding a wall with corners, keep in mind that you will need to cut blocks on every course. See How-to sheet #210: Cutting Blocks for more information.

Step 1: Layout

Determine the location of the first post/pillar. Install the Corner Blocks with the long sides facing out, align and level each course. Make adjustments as needed. See How-to sheet #220: Building A Post for more information on building posts/pillars. Continue building the post/pillar to the desired height. Alternate the blocks to offset the seams from the blocks below.

Step 2: Begin the Wall Panel

Start with wall panel with a cut block

The first and the last block of every course of wall panel between the posts/pillars will be a cut block. Using a cut block allows the panel to be flush with the post/pillar. If a standard angled block shape is used there will be a gap where the panel meets up with the post/pillar. Cut an AB Dublin to achieve a quarter (1/4) and three-quarter (3/4) length piece to start the first course. Place the quarter (1/4) piece with the cut side against the center of the post/pillar to start the first course followed by the next full block. Use the three-quarter (3/4) length piece to complete the end of this course where it will meet up with the next post/pillar. We recommend installing the first two courses of the wall panel at the same time to ensure proper alignment.

Step 3: Build the Second Course

On the next course, cut an AB Dublin in half (1/2) to start this course. Place one half of this block with the cut side against the post/pillar. Again, save the other half of this piece for the end of this course. To aid in fitting the cut blocks, try flipping them over so the raised rings are down.

Step 4: Building the Wall Panel

With the first two courses started, continue building the wall panel in the chosen pattern. Build to the location of the next post/pillar. At the end of each section place the remaining cut blocks (the 3/4 and 1/2 length pieces) on each course that was used to start the course.

Step 5: Additional Posts/Pillars

At the end of the wall panel, install the next post/pillar as previously done. Place the Corner Blocks with the long sides facing out. Install additional courses until the desired height is achieved. Alternate the blocks to offset the seams from the blocks below.

Step 6: Continue Building

With both posts/pillars built, continue stacking the courses of the wall panel to the desired height. Alternate the type of cut block for each course as you go.

Step 7: Finish

Finish the wall with Wall Caps and Post Caps. Secure the Wall Caps in place with a bead of flexible concrete adhesive along both sides of the raised rings and along the side of each Wall Cap. Place a bead of flexible concrete adhesive along the outside edge of the top course of Corner Blocks and then set the Post Caps in place.
