  • Patent number: 10557247
    Abstract: A reinforcement unit and methods are provided for creating footings for supporting structures, such as a fence post, using a reinforcement unit that has a tower that is generally perpendicular to a base, the tower defining a cavity for receiving a portion of the structure and an anchoring material. The reinforcement unit can include a top portion of a tower that is frangible. The base of the reinforcement unit can further include a pocket (or similar recess) substantially similar in width or diameter to the top portion of the tower such that a second identical reinforcement unit can be inverted and stacked on top of the second reinforcement unit.
