Styrofoam versus Void form

RE: Styrofoam versus Void form
Void form will crush under a specific load, so that it can support the weight of the concrete placement and then when frost heave or soil expansion occur, the upward force of the soil crushes the void form and allows the soil to expand.
Styrofoam is not designed to crush in that manner.

RE: Styrofoam versus Void form
In what context do you ask your question? Are you trying to form a permanent void in an inaccessable location where sacrificial formwork is needed or are you trying to form a void on grade? Or another application?
Thanks,
