About Under-Deck Drainage

Under-deck drainage systems transform the space beneath elevated decks from rain-soaked dead zones into dry, usable outdoor living areas. Dream Decks installs premium drainage solutions including Trex RainEscape that capture water falling through deck board gaps and channel it to gutters at the deck perimeter. The result is a covered patio area that stays dry even during Minnesota's heaviest rainstorms.

Trex RainEscape and similar systems install beneath the deck joists before decking goes down. The system consists of a trough network that captures water, directing it toward perimeter gutters and downspouts. Once decking is installed above, the drainage system is completely hidden from view on the deck surface. Looking up from below, the smooth ceiling creates an attractive appearance while efficiently managing water.

The dry space created by under-deck drainage offers tremendous value. Use it as a covered patio with outdoor furniture protected from rain. Add screens to create a screened porch beneath your deck. Install lighting to extend evening use. Some homeowners fully enclose the space as a three-season room with windows and heating. Properly engineered under-deck drainage makes all these options possible while protecting the area below from moisture damage.
