Under-deck drainage systems including Trex RainEscape and TimberTech DrySpace for elevated decks, dry patios, protected framing, lighting, fascia, and finished space below.
Compare Trex RainEscape, TimberTech DrySpace, and the lighting, fascia, ceiling, and drainage details that make the space below the deck actually usable.
RainEscape installs over the joists before deck boards go down, using troughs, gutters, downspouts, and tape to route water away from the framing and the space below.
DrySpace is TimberTech’s under-deck drainage option for elevated decks, helping route water away so the space below can be cleaner, drier, and easier to finish.
Drainage unlocks the ceiling below. Lighting, soffit-style finish details, ceiling material, and wiring should be planned with the drainage system instead of treated as an afterthought.
Under-deck drainage has visible edges, downspout paths, fascia transitions, and skirting decisions. The finished edge matters as much as the trough layout.
That space under your elevated deck? It doesn't have to be a muddy, dripping dead zone. Trex RainEscape® is an under-deck drainage system that keeps the area below your deck 100% dry — turning wasted space into usable outdoor living area.
Every drop of rain, every ounce of snowmelt — diverted away from your deck's substructure and out through downspouts. Your joists, beams, and fasteners stay dry and protected for decades.
A three-part system that keeps water out and lets you live below.
Flexible trough material installs between deck joists, creating channels that catch every drop of water falling through the deck board gaps.
Water flows from the troughs into a network of gutters along the joist edges, channeling it toward designated drainage points with a consistent slope.
Downspouts carry water safely to ground level — away from your foundation, away from the deck substructure, and away from the usable space below.
Complete coverage between every joist bay. No drips, no leaks, no moisture reaching your substructure.
One of the longest warranties in the under-deck drainage category. Install once, forget about it for decades.
Keeps screws and hardware dry, preventing corrosion and holding them tighter, longer. Your deck stays structurally sound.
Installs during deck construction or re-decking. Lightweight material, straightforward process — no specialty tools required.
Pair with Trex plug-and-play soffit lights for an illuminated under-deck ceiling. Drainage + lighting = complete outdoor room.
Turn dead space into living space. Outdoor kitchens, seating areas, hot tub enclosures, storage — the possibilities are endless.
Utah's climate isn't kind to unprotected deck substructures. RainEscape was made for exactly this.
Utah averages 50+ inches of snow annually in the valleys — much more in the mountains. All that snowmelt drips through deck board gaps and saturates your substructure. RainEscape catches every drop.
Utah's daily temperature swings cause moisture to freeze, expand, and thaw repeatedly — cracking wood and loosening fasteners. RainEscape eliminates the moisture that makes freeze-thaw damage possible.
Utah homes with walkout basements and elevated decks above are everywhere — and they're the perfect candidate for RainEscape. Protect the entry below and create a covered patio in one system.
Utah's summers are perfect for outdoor living. RainEscape turns the dead zone under your deck into a dry, usable area — dining, entertaining, storage, or a shaded retreat from the afternoon sun.
Add plug-and-play soffit lights to your RainEscape system for an illuminated under-deck ceiling. Ambient lighting transforms the space below into an evening destination.

RainEscape installs at the same time as your deck boards. Pair with any Trex decking line for a complete, maintenance-free outdoor living system.
Explore Decking →Trex RainEscape is an under-deck drainage system — a network of troughs and gutters that installs between your deck joists to divert water away from the space below. It keeps the area under your deck completely dry, turning wasted space into usable outdoor living area.
RainEscape is designed to be installed during deck construction or re-decking — it mounts to the top of the joists before the deck boards go down. If you're replacing your deck boards, that's the perfect time to add RainEscape. It's not practical to retrofit under existing boards without removing them first.
Excellently. RainEscape channels snowmelt just like it channels rain — through the trough system, into gutters, and out through downspouts. This is especially important in Utah where freeze-thaw cycles can cause significant moisture damage to unprotected deck substructures. RainEscape keeps all that meltwater away from your framing.
Trex RainEscape comes with a 25-year limited warranty — one of the longest in the under-deck drainage category. It covers material defects and gives you decades of peace of mind that your investment is protected.
Yes! RainEscape pairs perfectly with Trex soffit lighting. The plug-and-play lights mount directly to the trough system, illuminating the dry space below your deck. It's a popular combination — drainage above, ambient lighting below.
Absolutely. With RainEscape installed, the area below your elevated deck becomes a completely dry, protected space. Utah homeowners use it for outdoor dining areas, storage, hot tub enclosures, kids' play areas, and even outdoor kitchens. It effectively doubles your usable outdoor square footage.
