An interlocking building block for use in constructing mortarless walls in which the block has a first face shell in spaced relationship with a second face shell which define opposed inner surfaces for the block. Between the face shells, there stands at least one transversely-disposed bridge portion and a transverse end portion which defines an operatively outer surface for the block and which closes one end of the block between the first and second face shells. A grouting cavity is formed between the transverse end portion and a bridge portion. Both the transversely-disposed bridge portions and the transverse end portion have integrally-formed projections which extend above the height of the block on an operatively-upper surface and corresponding recesses are formed in an operatively lower surface of the block. Channels are formed in the opposed inner surfaces of the face shells which are adapted to receive and locate corresponding projections of an underlying interlocking block which is oriented orthogonally to the block, and the channels also define a reduced wall thickness in the first and second face shells which may be partially broken away to receive a reinforcement bar for reinforcing grout which is added to the grouting cavity. |
