To start this project, I found a textured background with a color that I liked. I think put it in photoshop, added text and used a brush tool to add cracks around the text.

I then took the photoshop file into After Effects without the text. I used a shatter effect to make it look as if the letters were being chiseled out of the wall. Pre-made dust effects were used as debris from the rock falling out of the wall. Finally, I used a shaking effect to make it seem a bit more realistic.

These are the layers used to make the broken wall.
