Concrete form apparatus and method of using
A concrete form apparatus includes a first component of a cardboard material and a second component of a core material. The first component is rectangular in shape and includes at least three perforations along a lengthwise dimension of the cardboard material. The second component is sized to fit within an internal cavity that is formed when the cardboard material is folded along the at least three perforations. The second component is placed onto the first component, and the first component is folded along the perforations to encapsulate the second component within the internal cavity to provide the concrete form apparatus. The first portion includes an inner surface facing the internal cavity, and the inner surface defines at least one extension inlet that is configured to receive and engage a corresponding extension outlet of a coupling apparatus for connecting the concrete form apparatus to another concrete form apparatus.
1 . A concrete form apparatus, comprising:
a first component composed of a cardboard material that is rectangular in shape and includes at least three perforations along a lengthwise dimension of the cardboard material; and
