Underside Deck Water Diversion System
Dek Drain. Constructed from a pliable commercial rubber membrane in black or white, this water diversion system captures rain water that drips through the deck surface and directs it toward the gutter system for drainage. Top-side products are used for new construction, while the Dek Drain Underside system is designed for existing decks and is installed on the bottom of the deck joists. 866-335-3724. www.dekdrain.com.
