Shower floor help needed!

The highest point of my shower floor will end up approx. 2" below
the bottom of the cement board. In between, this 2" is comprised of roughly-chipped concrete. Therefor, when I start with the bottom row, the tiles will attach to the wall only on their top half, creating a cavity along the bottom half of those tiles in row one. This is the problem that caused us to start this project. The builder neglected this, and many of the tiles were cracked and leaking into the walls. They also didn't use a liner! What can I do to ensure proper tile contact? I will try to attach a picture.

Sounds like you gotta tear that entire thing out because it sounds like a blind circus worker installed it.

Here's how your shower should be constructed. Ignore that the diagram depicts wood subfloor:
