ABSTRACT:
A paving method and a grab for carrying out the method. A group or unit of paving stones or bricks, arranged in a selected pattern, is clamped, picked up, and laid on a prepared sand bed, in contiguity with paving components already laid, by releasing the clamping and pressing against said paving components. Tilting or jamming of stones or bricks is prevented by the exercise of a downward force on at least the border stones or bricks or border rows bordering the paving components referred to at least at the moment when the clamping is released.
