AB Junior Radius
The 3° setback creates a coning effect in curved walls. The tightest curve you can build has a 28 in. (700 mm) radius. With each course you add below, the radius will need to be 1 in. (25 mm) larger.
The amount of wall rock needed for block cores and behind the block is 20 lbs per block (9 kg)
Experienced gardners and landscapers mark their designs with the classic cut stone look and style of the AB Junior. The AB Junior will take your garden design wherever you want it to GO!
This product currently has limited availability. Please check with your local manufacturer to see if the AB Junior is available in your area.
You can't find more potential, more possibilities, and more performance in a lightweight, easy to use block. AB Junior offers a world of design opportunity - and delivers professional results.
Soft Curves, Straight Lines, or Tight Radii
By adjusting the position of the standard blocks, you can get the line and look you want.

How to Build: AB Junior
Prepare The Base
Use a garden hose to mark the location of the garden wall. Remove the sod and other surface material.
Dig a shallow trench 10 - 12 in. (255 - 305 mm) wide and at least 6 in. (150 mm) deep, checking for level as you dig. On sloped sites, "step up" the trench when it gets more than 8 in. (200 mm) deep.
Place 4 in. (100 mm) of wall rock in the trench, level and compact thoroughly with a hand tamper. It is essential that the base is level at this point, as errors will multiply as each new row is added. On larger projects, consider using a mechanical plate compactor for best results.
Install The Block
Starting at the lowest point of the trench, begin placing the first course of block on the base with the raised front lip facing up and forward. Level each block from side to side and front to back, using the rubber mallet to make adjustments.
With the base course in place, carefully fill in and behind the blocks with wall rock, including a 4 - 6 in. (100 - 150 mm) space behind the block. Use on-site soil to fill in front of the block, and behind the wall rock to the same level as the top of the block. If installing pavers behind the block, be sure to prepare the paver base properly.
Compact thoroughly with a hand tamper or plate compactor. Good compaction is key to a quality job. Sweep the top of the blocks clean, and check again for level.
Place the next course of blocks with the seams offset from the course below by 2 - 4 in. (50 - 100 mm). This will make the wall stronger and lock each course more tightly in place. Backfill again with wall rock and appropriate soils to the top of the second row.
Compact again and repeat to the top of the garden wall.

Finish Your Garden Wall
AB Junior has several options for finishing the top of the wall. Choose the one that's right for your design.
Fill in the top course with planting soil or mulch, and use the raised front lip as a finished edge. No caps required.
Use the Two-Way for a clean, finished look. Glue the caps in place.
Mitred corners will give 90° corners a perfect finish with some cutting.
AB 12 in. Straight Caps provide the extra depth needed for comfortable stair treads. Be sure to fasten securely with adhesive.
Cutting Caps for a Mitre Joint Look
Using four of the Two-Way caps and with some cutting you can create a mitre joint at the corner for a custom look. Be sure to wear safety glasses when cutting, and operate power saws carefully.
Using a power saw with a masonry blade, make 45° cuts in blocks A & B and place on the wall at the corner.
Place block C against block B on the wall, mark the area to be removed. Repeat this same process for block D.
Use construction adhesive to secure pieces in place.
