Form assemblies disclosed herein include a form assembly having a reusabl e flexible form. The form can define a molding cavity having a shape corresp onding to the shape of a pier pad. The form assembly can selectively adjust the size and shape of the cavity such that different types of pier pads can be formed with a single form assembly. A user can determine the shape and co nfiguration of the form based using a table relating pier pads of a first sh ape to pier pads of a second different shape.
