A process for forming an artificial reef includes the steps of forming a form having a geometric shape, applying at least one blockout onto a surface of the form such that the blockout extends outwardly of the surface of the form, applying a sprayable concrete over the form and the blockout, curing the sprayable concrete on the form for a period of time, removing the blockout from the surface of the form and from the cured sprayable concrete, and removing the form from the cured sprayable concrete. A base is formed having an upper surface. The lower end of the form is positioned upon the base. The sprayable concrete is sprayed over the upper surface of the base.
