TimberTech DrySpace is perfect for second-story decks. Whether you have a porch or patio underneath, DrySpace will redirect water so you keep dry. DrySpace is an under-deck drainage system that collects and channels moisture from the spaces between the deck boards. Attaches easily to new or existing deck joists, and comes in an off-white color that will lighten and brighten the area under your deck. TimberTech DrySpace is made of solid extruded vinyl for maximum strength, durability, and weather resistance, and comes with a 25-year limited warranty.
