The pot-shaped brick with bottom opening is for the formation of planted cladding on a bank or sound-insulating wall. Seen in plan view, its four walls, roughly at right angles to the bottom, form an isosceles trapezium, whose sides (3, 4), including an angle, have recesses and protrusions (6, 7) engaging positively with adjacent bricks. The other sides (1, 2) form visible curved walls. ADVANTAGE - Can be assembled with others into a variety of configurations.
