No.

David,
Tarps degrade rapidly. Underground roofs require a heavy rubberized membrane like EPDM or a heavy peel-and-stick product or a pond liner -- and sometimes they require multiple layers of these heavy-duty membranes. They also require careful planning for drainage (using dimple mats, crushed stone, and perforated pipes.)
What are you building that requires an underground roof?
