Abstract: 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.
Abstract: 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.
Abstract: 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.

Abstract: An edging unit comprises a structure having opposed top and bottom surfaces, opposed first and second side surfaces extending between the opposed top and bottom surfaces, and opposed first and second end surfaces extending between the opposed top and bottom surfaces and between the first and second side surfaces. The top surface comprises at least one pair of opposed segments. Each pair of segments includes first and second segments respectively opposing one another with respect to a center of the edging unit. The first segment defines a first upward or downward slope between the first side surface and the second side surface and the second segment defines a second upward or downward slope between the first side surface and the second side surface generally opposite in direction to the first slope.
