Ah. O.K., now I am on the same page with you.
On a tiling job this fall, well 2 jobs one mine the other on the other side of rd, the help told me how much better the bank crumbled to cover the open 4''. The other side of rd just seen its first gyp application. I didn't check out your link yet, but we put gyp on for 15-20 yrs, asked osu and others about it at that time and basically said waste of money. How times have changed.
I sat down and ate breakfast with Mr. Warren Dick who gave me quite the graduate course cliffs notes in that 1/2 hour...LOL. He gave me the information I linked as well as a more in depth research paper which I can not source yet in my fertility folder.
I have not yet used gypsum on this operation, as I usually want the Ph correction of lime. And gypsum is priced awfully high for "here". One of these days though.....I need to get my feet wet on it.
