Dek Drain

Dek Drain is a product similar to Trex Rain Escape, but certainly superior. It’s sold primarily to DIY homeowners and to deck builders. 

This system is generally installed on a new deck, prior to the floorboards going on. They also have a product called Underside, which uses the same type of material to waterproof a deck that already has the floorboards on.
