To make strong connections between your courtyard wall panel and the post/pillar, you can extend the top course of wall panel into the post/pillar to interlock them together. If building a wall panel 5 courses high and taller, we recommend interlocking it into the post/pillar to help stabilize the wall.

Step 1: Build Wall Panel and Post/Pillar

Build the wall panel and the post/pillar to the desired height where they will be interlocked together. We recommend that this occurs within the top 1/3 of the wall to help with stability. See How-to sheet #190: Building Walls and Posts for information.

Step 2: Interlock

On the course to be interlocked, place a Corner Block half on the wall panel and half on the post/pillar. Slide the Corner Block so it meets up with the first raised ring on the wall panel block on the course below.

Step 3: Post/Pillar

Place three more Corner Blocks to build the post/pillar. The last Corner Block will need to be cut to fit. Measure and cut the Corner Block to fit the space. See How-to sheet #210: Cutting Corner Blocks for more information.

Step 4: Adhesive

Remove the interlocking course of blocks and secure with masonry adhesive. Place a bead of adhesive along the outside edge of the Corner Blocks and along the raised ring of the wall panel block where the Corner Block interlocks the wall and post/pillar together. Now replace the blocks and finish the wall panel section for the course.

Step 5: Continue Building Courses

On the top of the interlocking course, again place a bead of adhesive along the outside edge of the Corner Blocks and on top of the Corner Block that interlocks them together. Finish building the post/pillar and wall panel to the desired height as done previously.

Step 6: Finish

Finish the wall with Wall and Post Caps. Secure the Wall Caps in place with a bead of masonry adhesive along both sides of the raised rings and along the side of each Wall Cap. For the Post Caps, place a bead of adhesive along the outside edge of the top course of Corner Blocks and then set the Post Caps in place. (adhesive optional)
