A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

Retaining wall containing wall blocks with weight bearing pads

A wall block, wall block system, method of constructing a wall or other structure and a method of manufacturing a block wherein the wall block has a front, a rear, and two side surfaces, as least one of the surfaces consisting of multiple vertically planar surfaces of differing shapes and sizes and multiple faceted surfaces of differing shapes, sizes and contours.

The invention provides a block splitter device comprising first lower and second upper opposed block splitter assemblies. The block splitter assemblies have first and second forming edges that extend at least the majority of the distance from a first end to a second end of the block splitter assembly and have first ends disposed near a median split plane and second ends disposed further away from the median split plane than the first ends. Methods of using the block splitter device are described.

Block splitter assembly and method of producing wall blocks

The invention provides a block splitter device comprising first lower and second upper opposed block splitter assemblies. The block splitter assemblies have a centrally located depression extending the length of the assembly and two or more first forming blades. One forming blade is disposed to the right of and one forming blade is disposed to the left of the center depression. The forming blades have forming surfaces with first and second forming edges. The forming surface of the first block splitter assembly is opposed to the forming surface of the second block splitter assembly.

The invention provides a block splitter assembly comprising first lower and second upper opposed splitter blade assemblies. The splitter blade assemblies have a splitting blade and two or more first forming blades. One forming blade is disposed to the right of and one forming blade is disposed to the left of the first splitting blade. The forming blades have forming edges. The splitting blade has a splitting edge that is straight, and the splitting blade has a greater maximum vertical dimension than the maximum vertical dimension of the forming blades. The splitting edge of the first splitting blade is opposed to the splitting edge of the second splitting blade.

A wall block having at least one weight bearing pad on an upper or lower surface of the block and a compression head and methods of making the block and making walls with the block.

Wall block with weight bearing pads and method of producing wall blocks

A floating cut-off bar coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of side rails and a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the side rails and optionally division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.

Floating cut-off bar for a mold box

A floating cut-off bar that follows a preselected path of travel over a mold box during a block production cycle. The floating cut-off bar may be coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.
