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.
A shaped hollow building block comprising in combination, a base wall, side walls, and a face wall having the form of a shield standing perpendicularly to the base wall, having on both sides a margin projecting relative to the side walls and having a height greater than that of the side walls, the side walls and the base wall jointly forming an elongate trough in a direction normal to the face wall, and a transverse wall extends parallel to the face wall in the trough for dividing the inside of said building block into compartments, one of which is open at the rear of the building block opposite said face wall and at the top of the building block opposite said base wall, and the other of which is located between said one compartment and said face wall and is also open at the top of the building block opposite said base wall, with said side walls laterally delimiting both said one compartment open at the rear and said other compartment between said one compartment and the face wall.
A shaped building block comprising, in combination, a base wall, a face wall and side walls arranged to provide said building block with an open top opposite said base wall, and means for dividing the inside of said building block into distinct spaces, at least one of which is open at the rear of the building block opposite said face wall, the face wall having the form of a shield standing perpendicularly to the base wall, having on both sides a margin projecting relative to the side walls and having a height greater than that of the side walls, the side walls and the base wall jointly forming an elongate trough in a direction normal to the face wall, the shaped block including two compartments separated by a transverse wall extending parallel to the face wall in the trough and including reinforcing walls projecting outwardly from the side walls with a displacement relative to each other, whereby adjacent reinforcing walls engage behind each other when several shaped blocks are laid in courses.
