Abstract:

An apparatus and method for creating openings in a material that solidifies is disclosed. The apparatus comprises a rigid board and at least one rigid retainer plate. The rigid retainer plate comprises at least one buoyancy plate to resist the buoyant force of the material that solidifies, at least one hydrostatic plate to resist the hydrostatic force of the material that solidifies, and a retainer tie. The rigid board further comprises retainer plate slots configured to accept the retainer plates. When the apparatus is in use, the retainer plates are inserted into the retainer plate slots and the retainer ties are coupled to formwork panels. The material that solidifies is then poured into the gap between the formwork panels. Once the material is solidified, the formwork panels are removed and the apparatus can be either reused or thrown out. The apparatus may be used with any material that solidifies.
