An insulated concrete block assembly includes a plurality of blocks is provided and each of the blocks is comprised of a mixture of 60.0 percent Portland cement, 30.0 percent expanded polystyrene foam and 10.0 percent lime. The blocks are stackable on each other to define an exterior wall of a building. A fluid insulation is pourable into each of the voids in each of the blocks when the blocks are stacked, and the fluid insulation is comprised of 70.0 percent polystyrene foam. 25.0 percent Portland cement and 5.0 percent lime. A tensioning cable is provided and a base of the tensioning cable is embedded into a foundation upon which the blocks are stacked. The tensioning cable is tensioned to a pre-determined tension load when the tensioning cable is routed through the voids of the blocks that are stacked.

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.

A stackable growth media filled porous fabric block-shaped container includes an internal seed carrier to facilitate the growth of various plants from within the block. A plurality of the containers may be stacked or laid side by side to create a vegetated retaining wall or a vegetated slope facing. The porous fabric block-shaped containers are filled with growth medium that encourages plant growth, while allowing proper drainage and moisture retention. The seed carrier is a degradable or porous material coated with or supporting seeds and other amendments which facilitate plant growth.
