The present application includes a void form unit for creating a void space between concrete structures and expansive soil. The unit includes a cellular structure surrounded by a paper based shell. The cellular structure is impervious to moisture. Together the cellular structure and the shell make a singular rigid member. The rigid member is configured to temporarily support concrete and gradually increase in flexure so as to flex with the movement of the expansive soil. The shell is configured to weaken over time from the regulated absorption of moisture. The flexure of the cellular structure configured to increase with the deterioration of the shell.
