What to use under deck to make a shed?

[spence]

Deck is 9' above grade and has a gutter above it. Don't think water along the house will be an issue...

The shrink wrap idea has some great potential...simple and not that expensive. I'd like to keep the cost down, and the entire deck will be latticed in so you won't really be able to see it from the outside.

Thanks ! - spence

Spence,

When I bought my house 4 years ago, the old owners had that corrugated plastic put in place under the deck to store their sports car. Thusfar, it works great. Diverted to a gutter hung on the deck, it is pretty waterproof. Only problem is that in heavy rain, so much water pours out of the plastic, it blasts past the gutter and splashes under the deck. I was going to put another piece in the ground to divert that problem but built a shed instead. More room = more toys!!
