What is the difference between concrete and GypCrete?
While gypcrete, when properly installed, provides an ideal layer of underlayment, and it is an excellent floor leveler, it is not a structural element and you cannot rely on it to provide any structure and stability. Concrete, on the other hand, is used precisely for its structural strength and reliability.

brain, one good thing about gypcrete is that its fairly easy to remove. start by drilling some holes in a 1 ft sq area(like swiss cheese), then get a chisel about 1 ft long or so and chisel up that area. next chisel between subfloor and gypcrete at a low angle, pound in a couple of inches and lift!
