Goberco Under Deck Drainage System

Installed this under a deck we are building on a brand new house. It installed fairly easily. We were installing it in 14 and 16 ft runs. It was a two-person job. We used the recommended 4" Grace vycor as our flashing. Also a great product It rained for the first time last night and the patio below is dry. I compared it to another system that installs like soffit underneath the deck boards. The thing that sold me on this system was this actually protects the top of the deck framing. Too many times I have had to tear down a deck because the pressure treated framing has finally deteriorated. I would recommend this to anybody who wants to waterproof under their deck.
