Trex® RainEscape® Under-Deck Drainage System

Our unique under-deck drainage system keeps rain, spills and snow melt from dripping through the decking boards above, creating a dry area below.

Intelligent Design

Provides 100% protection of the deck substructure from moisture and holds screws in place longer.

Proven Reliability

Easy to install and backed by a 25-year warranty.


Trex® RainEscape® Under-Deck Drainage System

Double your outdoor living space with the Trex RainEscape under-deck drainage system. The trough and downspout design drains water away from your deck, allowing you to create a dry patio or storage area on the ground level below.


Trex® Protect Joist, Beam & Rim Tape

Protect your deck from moisture with Trex Protect - our seal-adhesive, non-skid deck flashing tape. This butyl-based tape shields joists, beams and rim joists from moisture that can lead to wood rot and decay.


Trex® RainEscape® Soffit Light

The RainEscape plug-and-play LED Soffit light is installed in the under-deck ceiling of a two-story deck. Two steel tension spring clips hold the downward light in place illuminating the space below.


Trex® Seal™ Ledger Flashing Tape

Trex Seal is a self-adhering ledger butyl tape with an aluminum liner, creating a watertight barrier around the entire ledger board. Use Trex Seal Ledger Tape to seal the gap between the ledger board and the deck substructure, and apply Trex Seal Sub-Ledger Tape behind the ledger board to prevent water penetration.
