Abstract
An interlocking block for use in the construction of a mortarless retaining wall wherein a plurality of interlocking blocks are stacked in a number of successive offset courses of blocks, a block in an upper row being in overlapping relation with respect to the joint between blocks in an immediately underlying row. The interlocking block comprises an interlocking member and a block body having top and bottom support surfaces and rear, front and side surfaces. The interlocking member has an interlock surface configured so that when the interlocking block is disposed over the joint between two underlying interlocking blocks, the interlock member is able to engage the upper edge surface portion of each such underlying block such that the front surface of the block is offset rearwardly with respect to the front surfaces of the underlying blocks and when the interlocking block is disposed over the joint between two underlying interlocking blocks, curved walls can be created without the necessity of providing different types of blocks for different types of applications.
