Corner Details

Document imprimable.pdf

Whenever possible we recommend using curves instead of corners for a smooth flowing look to your landscape. Our example uses an AB Jumbo Junior, but can be used with any block.

Inside Corners

Standard blocks are easily modified to build inside corners. You will need a concrete saw with a masonry blade to make the necessary cuts (a good chisel will work too).
  • Using your saw or chisel, remove the raised lip from one block, and the left third from another. Set them in place at the beginning of the base course.
  • Locate the adjoining wall so that the raised lip on the modified block is lined up with the raised lips on the opposite wall. Finish installing the entire base course in both directions.
  • Modify two more blocks, this time remove the raised lip from one block, and the right third from another. Use these blocks to start the second course.
  • Continue the process to the top of the wall, alternating as you go.
  • Cut caps at 45 degree angles to complete the inside corner and give the wall a custom finished look.








Outside Corners

AB Corner Blocks are all you need to make an outside corner. Always build your walls by starting at the corners and working out.
  • Set the first corner block in place and install the two perpendicular base courses. Level, backfill and compact.
  • Place an alternating corner block on the second course and set the entire second course of block in both directions. Level, backfill and compact again.
  • Repeat as often as needed to the top of the wall.
  • Cut caps at 45 degree angles to complete the outside corner and give the wall a custom finished look.
