Building Corners with AB Courtyard
How to Build A Patio Wall with Corners
The AB Courtyard Collection is designed to let you easily build corners using the Corner Block. These basic steps will help you learn how to build a simple wall panel either on an existing patio or on soil. Once you have the basics steps in hand you can build everything from seating walls, and outdoor rooms to kitchens, backyard bars and more.
Step 1: Layout
When building a wall with corners, keep in mind that you will need to cut blocks on every course. See How-to sheet #210: Modifying Blocks for more information.
Walls that have corners in the design will need to be built starting at the corner. Determine the location of the corner and place a Corner Block. Installing the first two courses at the same time will ensure proper alignment of the entire project.
Step 2: Build the Corner
Cut an AB Dublin Block to achieve a quarter (1/4) and three-quarter (3/4) length piece, see Pattern A. Place the cut end against the Corner Block to create the corner, see Pattern A. Cutting the block creates a straight edge so there will not be a gap where the blocks meet. An AB York Block cut to create a half (1/2) length block will also work.
See How-to sheet #210: Modifying Blocks for more information.
Step 3: Second Course
On this course, alternate the position of the Corner Block to face the opposite direction of the one on the first course, see Pattern B. Use the remaining cut piece and place it with the cut side against the corner to finish the corner.
Step 4: Continue Building
Build the remaining wall out in both directions in the pattern chosen. Use the above process for any additional courses or corners in the project. To aid in fitting the cut blocks, try flipping them over so the raised rings are down.
Capping a Corner
Step 1: Wall Caps First Direction
Finish the corner with Wall Caps. Starting at the corner, place the first two Wall Caps following the wall in the same direction. Place the first Wall Cap with the long end facing the outside of the wall. Alternate the direction of the second Wall Cap for a straight wall.
Step 2: Wall Caps Second Direction
Next place a Wall Cap on the other side of the corner. Place the short end of the Wall Cap facing the outside of the wall. Make adjustments to the first two Wall Caps to ensure they line up properly at the corner.
Step 3: Finish
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.
WALL CAP DETAIL - CHECK FOR AVAILABILITY
The majority of the Wall Caps are manufactured with a notch in the bottom that allows for placement on the wall panel with the raised rings from the blocks below.
Some Wall Caps may be manufactured with a solid edge for use when ending walls. Check with your distributor for availability.
Modifying Wall Caps for Corners (Optional)
CUTTING CAPS TO CREATE 90° CORNER
Finishing the corner with Wall Caps can simply be done as shown above by placing the blocks to create the corner. Modifying two caps slightly will give the corner a more refined look.
Step 1: Mark and Cut Caps
Using a tape measure and straight edge, mark the cut line on two cap blocks as shown. Use a masonry saw with a dry cutting diamond blade to make a complete cut.
Step 2: Place Caps on Corner
Place the cut caps on the corner as shown. Continue stacking additional caps out from the corner.
Step 3: Finish
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.
SAFETY FIRST
Always wear safety glasses when splitting or cutting block. A dust mask and ear protection are also recommended when cutting block.
