Despite the recommendations received, I totally follow my instinct on that one, and decided to lay the bricks with some mortar, instead of using brickies sand.
It works, it prevents the bricks from moving downwards and as a bonus, it should last a lifetime.
Great job, and a nice step to get into that charming property.
