I am currently having a home built. Our slab is a post tension slab. I was told that the foundation was poured sometime during the week of March 10. It has been partially pulled; however, it has not not been pulled all the way. It is now the 27th. What is the standard time frame by which the slab should be pulled all the way? If it is done after the right amount of time, how does this affect your foundation in the future?
