Most floors are horribly out of level. I'm sure you already knew that. 
Your comment was out of line.
Why is adding more indestructible material to a floor over properly installed tile underlayment a "crime". |
The OP said it is
new construction and the floor is 1/2 inch out of level in 4'. If there is frame construction under the floor a responsible builder would find out
why it is 1/2" out of level and correct the original problem, not patch it over.
