Brick landscape border
I am thinking of using some reclaimed Chicago bricks to make a landscape border. One side of it will be grass and the other side a plant bed with mulch.
These bricks are not full size bricks but half bricks, size approximately 2"x2"x8". The soil down here in Miami is sandy. I am planning only two courses of these bricks, so the bricks would end up being 4" total in height, but the first course will probably be completely buried in the ground.
Since the bricks are narrow, I don't think I can just trench, compact, level the ground and drop them in like the larger stones. I think I will need something to stablize it.
Should I dig a trench say 2" deep, 4" wide (twice as wide as the bricks), then mix some concrete to a very wet consistency and pour into the trench 1" deep, then drop the first course of bricks into the trench, hence they will be sitting half way in the concrete?
Then wait for it to set, then lay in the next course using standard mortar?
Is this the best way or are there other options?
