Hi,
I want to install a lawn edging stone along a slope as a boundary. On one side, it should slightly protrude, while on the other side, a small path should run flush with the top edge. In other words, there should be a step along the edge. Ideally, the step should be about 20cm (8 inches) high.
The affordable standard stones are usually only 25cm (10 inches) high, but they are also often available in 30 or 40cm (12 or 16 inches) heights.
The question is: how much of the edging stone needs to be concreted or buried on both sides below ground to ensure it stays firmly in place?
I have seen many pictures where edging stones are used as step borders for patios or garden stairs. The steps there typically stand about 15cm (6 inches) high and are visible from the front. Or for flower beds adjacent to lawns, where the beds are at least 10cm (4 inches) higher than the lawn, and one side of the edging stone is clearly visible.
Is there perhaps a rule of thumb stating that one-third or half of the stone needs to be set in concrete to hold firmly? If I were to use a 40cm (16 inches) stone, would a concrete depth of about 20cm (8 inches) be enough?
Thanks and good luck
