This disclosure provides methods, systems, and kits for building seawalls using mechanically interlocking blocks. The interlocking blocks have interiors that can be filled with sand, gravel, or cementitious material after formation of a wall. The interlocking blocks that can be connected on any side to form a structure, wall, foundation, floor, building, flotation device, gardening structure, or toy. The interlocking blocks typically comprise center openings and connecting openings on each side and can be connected with hardware through the connecting openings. The center openings allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked blocks. Connected blocks can also be filled with fortifying material to strengthen the structure. Sides of connected blocks can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connectors for connecting sides of the interlocking blocks.

The present disclosure provides a building block (100) that is designed to hold utilities, including but not limited to, electricity and plumbing. The building block (100) of the present disclosure can resist compression forces and moment and can connect to other building blocks (100) to form a modular wall system with the ability to distribute the forces in a way that reduces the stresses on each individual block. The building block (100) of the present disclosure may include a body with an upper end (11) and a lower end (10), one or more main compartments (16, 17), and one or more inner pass-through openings (19), wherein the upper end (11) comprises a first upper cut (13), a second upper cut (14), and one or more protrusions (18), and the lower end (10) comprises a first lower cut (12) and one or more slots (110). The present disclosure also provides a building system including more than one multi-purpose building blocks (100) and a base (2).

A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. First and second spaced apart formations are located at a rear of the block body and define therebetween a vertical fastener channel. The vertical fastener channel is adapted for receiving a complementary shaped formation of a rearwardly placed embedment block.

A concrete building block includes indicators along each end to assist in aligning a pin placed in the block with a channel in a like block in a course below as a wall is being constructed.

The panel-modular layered wall system for shaping spatial structures is characterised by the fact that: the arrangement of horizontal layers configured by means of joined sideways panels of various shapes, filled with the substrate, whose surfaces are planted with plants according to the principle of bipolarity, preferably using transparent or opaque panels, which are mounted on cantilevers with a variable supporting angle, always forms the horizontal arrangement of panels, placed a maximum of three (when with plants and more when without) on the flat or bent frame of the module in the shape of a rhombus, a rectangle and a trapezium made of a closed profile with a rectangular cross-section, where the frames of modules joined together along the perimeter by means of couplers form the vertical load-bearing frame, sloping load-bearing frame, arched-barrel load-bearing frame, spherical load-bearing frame, cylindrical load-bearing frame and sloping cylindrical load-bearing frame, which, together with the use of silos filled with the substrate, joining individual panels and layers, forms self-supporting layered wall structures in six variants, which can be configured with each other.

A retaining wall block includes a block body having a top side and a bottom side parallel to the top side, each of the top side and the bottom side being trapezoidal in shape and symmetrical with respect to a central vertical plane; a front side and a rear side parallel to the front side; and a right side and a left side opposite the right side. The retaining wall block includes a vertical interlock system having a groove having a groove depth and a groove width and extending transverse to the central vertical plane along the bottom side from the left side to the right side; and a key extending transverse to the central vertical plane along the top side and having a maximum key width that is smaller than or equal to the groove width, the key having a maximum key height that is smaller than or equal to the groove height, wherein the key has a left side portion and a right side portion, and each of the left side portion and the right side portion is shaped to reduce in width toward both the left and right sides of the block.

Embodiments of the present invention disclosed herein include a kit for assembling a vertically-oriented barrier (40, 70), a barrier (40, 70) assembled from the kit, and a method of manufacturing such kit. The barrier (40, 70) is formed from at least two differently-shaped interlocking components (20, 26, 50, 60), and each interlocking component (20, 26, 50, 60) has at least one recession (22, 24, 52, 66), at least one protrusion (28, 54, 64), or both. The protrusions (28, 54, 64) are inserted into the recessions (22, 24, 52, 66) to produce a barrier (40, 70). The interlocking component (20, 26, 50, 60) may be produced by slicing suitably-shaped rods (160), and the rods (160) may be produced by extrusion.

A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

A retaining wall block including a pair of curved engagement surfaces extending convexly from a rear side of the block and being symmetrical about a transverse axis are configured to engage a planar surface of a setback lip of similar overlying blocks when stacked in successive courses to form a wall structure, where the curved engagement surfaces maintain a desired setback distance successive courses for straight, convex, and concave wall structures.
