Thank you! Apparently my Google skills aren't what they used to be. Very sad day indeed. Thank you very much for finding that for me! I had been thinking 10x20 could work.

That depends on how the truck driver unloads. I have had numerous loads, ranging from 5 cubic yards to 20 cubic yards on paved drives and have never put a tarp down since it is not needed and creates more problems than it would solve.

It does make it harder to scrape material off the pavement below. If it's not going to sit more than a few days, I would just put it on the pavement. If you want to keep moisture from leaching into the pile and staining the concrete, put the tarp OVER the pile instead.

I've had countless loads of mulch dumped on my driveway over the years and I have to say that the thought of using a tarp never crossed my mind nor did my husband and I ever discuss it.

There has never been any kind of permanent staining but I suppose it's possible.

Also, it would take inches of rain to soak down very far into a pile of dry mulch. Unless there's a monsoon coming, it's probably not worth the trouble.

The main reason I was wanting to put something under it was for cleanup purposes. Easy to roll the last scraps up into a pile. My driveway already needs repair so not worried about damage.

Good to know it won't soak down much since the mulch is being delivered sometime tomorrow and there is a chance of rain tomorrow too. Sure more weight to transport if it rains while I'm moving it, but other than that not worried. It'll get rained on in the garden anyway.
