This is probably a bad foam quality. A good decent foam quality have no ploblem with small bricks, but can have with large pieces.
But for me it's hard to believe even the best foam agent with the best foam machine, able to create foam as good as shaving cream, could cast large pieces like they showed in the video link I posted.

Anyway, in a video a guy compared different foam agents, using the same foam machine, and checking how much each foam agent was able to stand without shrink. The agent suggested by Gaia wasn't the best in performance in the test video.
Unless Gaia's Little Dragon (foam machine) it's much better than most foam machine, I can't believe they can cast large pieces. If they can somehow, the bottom it's much denser than the top, due gravity concentrating the foam at bottom.
