Waterproof Panel for deck water control?
I’ve got a 24’x10′ ipe deck which is on the 2nd floor of my home. It’s insanely massive, held up by 24″ dia. galvanized culvert filled with concrete. I’m pretty sure it would hold a Kenworth parked on it.
Problem is that the area below is in front of my garage doors, and, during Iowa football home games (we’re 300 yards from Kinnick stadium), it’s the refuge from the rain. The water drips between the decking and onto anyone standing below. I’m looking for a waterproof panel I can use under the deck joists to direct the water away from the folks below- any ideas? I can pitch it 1/8″ per foot no problem, but I don’t want something that looks like hell or rots in 2 years.

I remember someone touting some method of keeping under-decks dry, but I can't remember who or when. Someone else has to help with this one.

I have seen advertisements in the magazine for panels that are fittedbetween joists to divert water like that. I think they are PVC and have heard they are expensive.
I have a similar situation at one of my decks but have always assumed that ice and other debris would create a problem in the diversion pans so I avoid them.
Another thought would be one of those retractable awnings over the deck above. It would shed the water for both decks and provide shade when desired.

Built an Eon deck last year and used "Underdeck" panels below so they could put a hot tub under it. Saw it in a magazine, bought it at Lowe's. Looks and works good. Try Underdeck.com.

There are lots of underdeck drain systems out there, and they are all slightly different - from what I've seen. Some fit between the joists, others cover the entire underside of the framing. Some are metal, others are plastic. Some are thin, others are thick. Pay attention to color options as well, because many have only two choices of color, others have dozens.
You might start by hopping onto the deckexpo.com or professional deck builder magazine (not sure of the website, but it's a division of Hanleywood.com) and looking at their advertisers - that's where these companies are promoting this type of product.
