Abstract: A business model algorithm and an apparatus for forming landscape edging blocks in which preforms of a dry concrete mix is first formed into a preform after which the preform is formed under pressure into an edging block shaped so as to nest with like edging blocks in such manner that a continuous edging may be formed in linear or non linear shapes.

Abstract: A method and apparatus for forming irregular, and regular, edgings for landscaping, and the like, exemplified by the use of specially constructed blocks, or bricks, having ends with curvatures such that irregular designs may be utilized and irregular or unusual terraine may be accommodated without the necessity of having gaps or spaces between various elements in creating an irregular design; One portion of each block will be curved in a convex manner. Another portion will be curved in a concave manner. The curved ends may be in one plane, or in more than one plane with overlapping and underlapping ends being curved appropriately. Appropriate scoring or marking may be provided to break blocks intermediate therein to form a square end to a particular edging design if desired; alternatively pegs are provided to match holes in portions of the blocks; or, holes are provided all the way through certain of the matching block elements in order to drive stakes through and into the ground if desired.
