what kind of flooring/mat/pad may be used on a section of the floor as a base for storing items and is also slippery enough to be able to glide/push/pull items on top of it?
Edits:
Crawl space floor is concrete, but not flat or level and slopes as one end is taller than the other.
The lowest height of the space is about 32” from floor to bottom of floor truss. Tallest height about 40”.
Open to both permanent and temporary solutions.
Part of the goal is to have the items off the concrete, the other part ease of moving it around in a constrained space.
Items would most likely be boxed or bagged, so a surface that would allow cardboard boxes, plastic bins, or sturdy plastic bags to be moved easily would be great. To put it another way, it’s much harder to lift and carry something standing on my knees, so the ability to push or pull an item easily, without damaging it on the uneven concrete, is desired
