What do I specify when I go out for bids?
2,200 sq. ft. crawl space with a grade to floor height ranging between 4' at one end and about 10' at the other. A full basement is not in the budget, but it would make for some really useful storage space.
So, I would like to put in what some on this forum have called a 'rat slab', i.e. a thin layer of cheap cement.
The grade has about a 1' in 10' slope.
I'm not expecting anything more than a garden rake finish, some cracking is inevitable, and no structural strength required.
In my mind, this means they strip off the topsoil when they do the grade work for the rest of the foundation, put down a vapor barrier, and pour a couple of inches of cheap cement. Is that really what I ask for?
