Install Guide

Patio wall panels are designed to let you easily build curved or serpentine walls. 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 ponds, fire pits and more.

Step 1: Build the Wall to the Start of the Curve

Courtyard Curves: Courses must be parallel

Install the first two courses of wall panel up to the approximate location where the curve will begin. Building the first two courses at the same time ensures proper alignment.

Step 2: Adjusting the Layout of the Curve

Before beginning the curve check to make sure that both courses are angled correctly. Both courses need to be parallel with each other and angled toward the direction of the curve. If one block is angled the opposite direction, remove the last block and slide the entire course over one block to correct.

Step 3: Begin the Curve

Starting a Curve

On the first course, install an AB York block by placing the long side of the AB York block facing the outside of the curve. On the second course, where the wall changes from a curve to a straight section, an AB Dublin will need to be cut in a half (1/2) length to be used at the transition. This transition piece will be needed on every other course. See How-to sheet #210: modifying Blocks for more information.

Step 4: Build the Curve

With the curve started, stack additional courses using the AB York block and placing all of the blocks with their long sides facing the outside of the curve.

Step 5: End of the Curve

To change the direction back to a straight wall, on the first course at the end of the curve, turn the AB York block around so the short side of the block is facing the outside of the curve. On the second course use the other AB Dublin half (1/2) length piece with the cut side facing out and toward the next section of the wall panel.

Step 6: Additional Courses

Repeat this same process as described in Steps 2-5 for any additional courses. Every odd and even numbered course will be layed out exactly the same with block layout and where the cut blocks will be used.

Step 7: Finishing

Finish the wall with Wall Caps. On curved walls, place the long end of the Wall Caps facing the outside of the curve. Secure them in place with a bead of flexible concrete adhesive along both sides of the raised rings and along the side of each Wall Cap. Learn more about capping your patio wall.

Courtyard Circle    Courtyard AB York Block

Full circle is 28 blocks

  • A pre-designed diameter is 81 in. (2.0 m). It takes 28 AB York blocks to make a complete circle. To build a larger radius or other circle options, see building large curves.
  • AB York blocks come with a built-in angle on both sides of the block, making it easy to create curves and circles. When building with both straight and curved sections, an AB Dublin half (1/2) length block will need to be used on every other course to transition between them.
