Inside Corners

AB Blocks are easily modified to build inside corners. To construct an inside corner, you will remove part of the raised lip on one block on each course.
  • Use a saw with a diamond blade or a chisel to remove half of the raised front lip. This allows the next course to be installed on a level surface (Step 1).
  • Lay the modified block perpendicular to another AB unit. This creates the corner (Step 1).
  • On the next course, remove the opposite half of the lip of an AB unit and position it over the right angle corner (Step 2).
  • On each successive course, simply reverse the position of the modified block to obtain an interlocked corner.

Outside Corners

Start construction of all walls at the corner. This will keep the block alignment within the 3 in. (76 mm overlap required).

Step 1

  • Allan Block Saw three as specified in Figure A and B. Note: Five Allan Block 2 are required for full corners.
  • Place the cut blocks on the foundation.
  • Make sure the blocks are level in both directions.

Step 2

  • Take a part (or C E) of the corner away and spread it in with concrete adhesive.
  • Place the block back and make a right angle and fixed .

Step 3

  • All cavities around the block and carefully split the material filling the blocks in his place.
