<strong>Build</strong>ing A Large Radius<br />
Basic Steps f<strong>or</strong> <strong>Build</strong>ing a Large Radius Curve<br />
The AB Courtyard Collection is designed to let<br />
you build a variety of <strong>radius</strong>es from circles to<br />
sweeping curves. If building on soils see Howto<br />
sheet #120 f<strong>or</strong> m<strong>or</strong>e inf<strong>or</strong>mation about layout.<br />
To build a <strong>large</strong> <strong>radius</strong> curve you will use a pattern of blocks<br />
that is repeated throughout the curve. This pattern uses<br />
three AB Y<strong>or</strong>k blocks to create a <strong>radius</strong> of 112 in. (2.8 m).<br />
See the other patterns f<strong>or</strong> <strong>large</strong>r <strong>radius</strong>es on page 3.<br />
Step 1: <strong>Build</strong> First Course<br />
Once the location is determined, start the first course<br />
by placing two AB Y<strong>or</strong>k blocks <strong>with</strong> their long sides<br />
facing out. Place the last block in the pattern <strong>with</strong> its<br />
sh<strong>or</strong>t side facing out. Repeat this pattern f<strong>or</strong> the<br />
length of the curve. When building curved walls it is<br />
best to build the first two courses at the same time.<br />
This helps align the blocks so additional courses<br />
continue to stack up properly.<br />
<strong>Build</strong> a Full <strong>Circle</strong>:<br />
You can build a complete circle <strong>with</strong> AB Y<strong>or</strong>k<br />
blocks. <strong>Build</strong> the circle by placing 28 AB Y<strong>or</strong>k<br />
blocks <strong>with</strong> their long side facing the outside of<br />
the circle to complete the first course. Make<br />
adjustments as needed to fit the blocks. This is<br />
the tightest circle that can be made. Stack additional<br />
courses as desired. Finish <strong>with</strong> Wall Caps.<br />
Step 2: <strong>Build</strong> Second Course<br />
Use the same pattern on the next course. To start, place an AB Y<strong>or</strong>k block<br />
<strong>with</strong> its long side facing out centered over two AB Y<strong>or</strong>k blocks, <strong>with</strong> their long<br />
sides facing out. Place the next block <strong>with</strong> its long side facing out next to it followed<br />
by one <strong>with</strong> its sh<strong>or</strong>t side facing out to complete the pattern. Again,<br />
repeat this pattern f<strong>or</strong> the length of the curve. Adjust the blocks as necessary<br />
to align them along the curve and equalize the small spaces between them.<br />

Step 3: Continue <strong>Build</strong>ing<br />
Using the same pattern continue building any additional courses to the top of<br />
the wall. Always start the pattern on a new course <strong>with</strong> a AB Y<strong>or</strong>k block <strong>with</strong><br />
its long side facing out over two of the same.<br />

Step 4: Wall Cap Pattern<br />
Finish <strong>with</strong> Wall Caps using the same pattern as done <strong>with</strong><br />
the AB Y<strong>or</strong>k blocks. Place the first Wall Cap <strong>with</strong> its long<br />
end facing out centered over two AB Y<strong>or</strong>k blocks, <strong>with</strong> their<br />
long sides facing out. Place the next cap <strong>with</strong> its long end<br />
facing out next to it followed by one <strong>with</strong> its sh<strong>or</strong>t end facing<br />
out to complete the pattern. Repeat this pattern f<strong>or</strong> the<br />
length of the curve.<br />

Once all the Wall Caps are in place, secure them in place <strong>with</strong> a bead of<br />
masonry adhesive along both sides of the raised rings and along the side of<br />
each Wall Cap (adhesive optional).<br />
Alternate Pattern<br />
This example showed how to build using only the AB Y<strong>or</strong>k blocks. You can<br />
also build this same curve <strong>with</strong> a mixture of AB Y<strong>or</strong>k and AB Dublin blocks<br />
by replacing two AB Y<strong>or</strong>k blocks f<strong>or</strong> one AB Dublin block that have<br />
matching angles.<br />

<strong>Build</strong>ing A Large Radius<br />
Use the following two patterns to build <strong>large</strong>r <strong>radius</strong>es. When building curved walls<br />
it is best to build the first two courses at the same time. This helps align the blocks<br />
so additional courses continue to stack up properly.<br />
Pattern 2: 75.5 in. (1.9 m)<br />
Use the pattern below to build a 75.5 in (1.9 m) <strong>radius</strong>. Start by laying out this pattern using the AB Y<strong>or</strong>k blocks.<br />
If you would like to inc<strong>or</strong>p<strong>or</strong>ate AB Dublin blocks in the pattern replace two AB Y<strong>or</strong>k blocks <strong>with</strong> one AB Dublin<br />
block where the angles match. See page 2 f<strong>or</strong> m<strong>or</strong>e inf<strong>or</strong>mation.<br />
Pattern 3: 184.0 in. Radius (4.7 m)<br />
Expand on the pattern above by adding two m<strong>or</strong>e AB Y<strong>or</strong>k block to the pattern will increases the <strong>radius</strong><br />
to 184 in. (4.7 m). To inc<strong>or</strong>p<strong>or</strong>ate AB Dublin blocks replace two Y<strong>or</strong>k blocks where the angles match.<br />
