The alternative is having the material be a part of the bid, which tends to be padded and unless you are very, very clear they will go the cheap route, i.e. cement/wonder board is ideal in baths, but greenboard is acceptable. 

My opinion is that only cement board should be used.

Its nothing special it has an old 87' 3/2 trailer and a cement block 3/1 house both houses share utilities.

I can think of ways to inflict $50,000 worth of damage with a crow bar and a bag of cement.   

Sometimes waterproofing is not needed and simple grading or cement work around the foundations can alleviate this problem for a lot less than 19000.

@Daria B.Removing portland cement siding w/ asbestos content is a low risk and relatively inexpensive abatement that a regular contractor or building owner can perform if they take a few easy precautions.

Typically, if that bottom stuff is through a turnkey company offer, that will nearly cement in turnkey stone fashion zero profits ahead.

Im now looking at a bunch of cement work that will costs me thousands.

I pulled up my carpet and pad and found a weird cement patch that had been poured over a low area in the slab.
