  • Patent number: 6012254
    Abstract: A trenchless landscape edging system and corresponding components and methods are disclosed. The system includes a plurality of anchoring members, an edging member having no or substantially no barrier extending downwardly therefrom and corresponding interconnecting or adjoining blocks having recesses disposed therein. The blocks, in combination with the anchoring members and the edging member, may be employed to separate adjoining lawn, garden, walkway, driveway or other areas from one another. The present invention permits the effects of undesired displacement forces acting on the blocks, such as frost heave, to be reduced or minimized and further permits rapid installation of the system since no trench for receiving lawn edging need be excavated.
