A shaped hollow building block suitable for lining bank slopes at the ground water level has a face wall in the form of a shield standing perpendicularly to a base wall, includes on both sides a margin projecting relative to side walls and has a height greater than that of the side walls. The side walls and the base wall jointly form an elongate trough in a direction normal to the face wall. The shaped block includes two compartments separated by a transverse wall extending parallel to the face wall in the trough and includes reinforcing walls projecting outwardly from the side walls. A building block for walls which are laid in courses without mortar and can be stabilized by planting, has a face wall, two domed side walls, and a base wall having rounded transition sections to the face wall and to the side walls. The block includes at least two curved dividing walls bounding a central space and two outer spaces between the side walls, with the upper edges of the face wall, of the side walls and of the dividing walls lying at least approximately in one plane. |
