Somebody said "pave." When the house I saw was done, nobody said "grade."
The concrete under that house went up and down with the grade under the house; nothing was too terrible but you sure couldn't use a crawler. The height under there was about three feet, so sweeping would have been quite a pain. Add to that... it wasn't my house. I was a visitor under there for about 48 hours of labor.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
