{MAYA} How to lock the depth of a surface?

robdeep

Hey everyone, I was wondering if any of you could help me answer the above question. I am working on a scrapyard and would like the mounds to form up from a flat surface. Is there a way to lock the depth of the surface so it cannot drop below that point?

I hope I'm explaining this corretly. I find half the difficulty is not knowing how to phrase the question as I may be missing some crucial piece of jargon.
