For that you will need to combine 1 part Portland cement, 2 parts builders sand, ½ part peat moss or black potting soil, ½ part clay soil with clods broken up, acrylic fortifying additive, and water. Then line up a layer of your hypertufa blocks, apply the mortar mix on the top of the layer, and repeat the process until you’ve put together the retaining wall.
