1 Corinthains 3:12-15 is all but inexplicable in a Heaven and Hell only theology.
If anyone builds on this foundation with gold, silver, precious stones, wood, hay, or straw, the work of each will come to light, for the Day will disclose it. It will be revealed with fire, and the fire (itself) will test the quality of each one's work. If the work stands that someone built upon the foundation, that person will receive a wage. But if someone's work is burned up, that one will suffer loss; the person will be saved, but only as through fire.
