A hardscaping unit includes a first block fixedly attached to a second block. The method of assembling the hardscaping unit includes the steps of forming a first block from a first material, placing a second material into a mold, contacting a surface of the first block with the second material that is in the mold, maintaining contact of the surface of the first block with the second material while transitioning the second material from a first state to a second state, the second state being more solid than the first state, and when in the second state the second material forms a second block that is fixedly attached to the first block.

A block for decorating an outer wall or an inner wall in construction work and a construction method for bricklaying work, and more particularly, to a wall structure using blocks and frames each having a wedge-shaped coupling part formed therein and a method of constructing a wall using the same, wherein frames, which are integrally formed with beams, slabs, and pillars of a building to serve as a frame structure, are fixed and mounted, an isosceles triangular wedge-shaped concave groove or protrusion is formed on inner surfaces of the mounted frames, and blocks and intermediate blocks, in which an isosceles triangular wedge-shaped concave groove or protrusion is formed, are laid on the frames, thereby solving a disadvantage of bricklaying work in that it is vulnerable to horizontal vibration and improving seismic performance.

In some embodiments, a building block includes alignment elements that interlink with a similar block with a positional offset. For example, the positional offset may be linear and/or rotational. For example, the second cinder block may be rotated with respect to the first block on which it is supports. Optionally, protrusions from the top of the block are positioned to interlink to the vertical slots at a fixed offset between the blocks. Optionally, the protrusions are formed by channels on a mold and/or a mold head. In some embodiments, a structure may be built stacked blocks. Optionally, a decorative face is configured to form a continuous decorated surface across offset blocks. In some embodiments a building block includes a calibration feature. For example, the block may include a ridge on the top of the block that may be shaved and/or ground to adjust the height of the block.

A hardscaping block includes a dry cast concrete backer block having angularly arranged contact surfaces and an integrated wet cast concrete veneer block chemically bonded to the contact surfaces, the veneer block having an exteriorly facing simulated stone surface. The integrated backer block and veneer block form a cast stone corner hardscaping block.

Building blocks include a tongue and groove on each block that allow the blocks to be placed in a way that interlocks the tongue and groove of one block with the corresponding groove and tongue, respectively, of another block facing the opposite direction. In a first embodiment, the same building block that has a decorative front face is used for both sides of the wall, resulting in a wall with opposed finished surfaces. In a second embodiment, a first plurality of blocks that have a decorative front face are used for one side of the wall, while a second plurality of blocks that have a thicker and non-decorative face are used for the other side of the wall, with the first and second plurality of blocks interlocking back-to-back via their respective tongues and grooves. Both types of blocks can be made using the same concrete form.
