Under Deck Waterproofing by Back To Nature

Convert the Wasted Area Beneath Your Deck into a Dry, Durable, and Functional Space

In Oreland, PA, decks take a beating. Rain, snow, and freeze-thaw cycles don’t just affect what you see—they impact everything underneath. If your elevated deck leaks onto the patio or the area below, that space stays unusable for most of the year. At Back To Nature, we build custom under deck waterproofing systems that stop the dripping, redirect the water, and create a clean, dry zone you can finally put to good use.

We’re not just a deck contractor—we’re a waterproofing builder and deck installation expert who understands framing, drainage, and the finer details of what works in Southeastern Pennsylvania’s climate.

What a Dry Space System Does—and Why It Matters

Water always finds a way—unless you give it one. That’s the principle behind every Dry Space/Waterproofing installation we complete. These systems are installed below the deck framing and above the joists, forming a pitched drainage plane that routes water into gutters and away from your home’s foundation.

  • Stops Water Infiltration at the Source: Our under-deck waterproofing systems prevent water from seeping through deck boards and pooling underneath. No more saturated concrete or wet walkways.
  • Protects the Joists and Framing: By redirecting water before it hits the joists, we reduce the risk of wood rot and preserve the structural integrity of your deck.
  • Creates Usable Storage or Seating Areas: Once water is controlled, the space under your deck becomes viable for enclosed storage, seating areas, or walk-out patios.
  • Reduces Mold, Mildew, and Wood Decay: Controlling moisture reduces biological growth and preserves the health of your outdoor space.

Engineered Waterproofing Systems for Real Pennsylvania Weather

Season Challenge Back To Nature’s Solution
Spring Thunderstorms, heavy rain, flash floods Slope-controlled drainage Planes are pitched at 1/4″ per foot to move water swiftly into a dedicated gutter system. This eliminates standing water under the deck and prevents water from pooling near your foundation.
Summer Intense storms, wind gusts, high humidity Custom Gutter Tie-Ins include sealed downspouts and direct connections to your home’s gutters. These ensure water exits efficiently—even during high-volume rainfall—without damaging the structure or landscape.
Fall Hurricane remnants, wind-driven rain, wet leaves Pressure-treated flashing and Seals block water at framing contact points using butyl tape, corrosion-resistant fasteners, and sealed joists. These protect structural members from rot and prevent leaf buildup at drainage entry points.
Winter Snowstorms, freezing rain, ice dams Ice and Debris Management uses removable drain covers and open-access points for clearing ice, slush, and frozen debris. This reduces pressure buildup and helps prevent joist movement or cracking from freeze-thaw cycles.

Drainage and Ceiling Features That Make Your Dry Space Functional and Reliable

Drainage Feature Ceiling Feature
Slope-Controlled Drainage Planes: Panels are pitched at 1/4″ per foot to direct water to a dedicated gutter system. This keeps water moving, not sitting. Aluminum Ceiling Systems are lightweight, rust-resistant, and low-maintenance. Panels lock together with a tongue-and-groove profile that conceals fasteners.
Custom Gutter Tie-Ins: Downspouts and tie-ins connect to your existing gutter system, creating a seamless water exit plan. Vinyl Ceiling Systems: Cost-effective and versatile, available in vented or solid profiles to match ceiling height and airflow needs.
Pressure-Treated Flashing and Seals: We use joist tape and treated lumber to prevent water intrusion at framing contact points. Lighting Integration: We install conduit and junction boxes for recessed lights, sconces, or ceiling fans as part of the framing plan.
Ice and Debris Management: Removable drain covers and open-access points make removing leaves and preventing ice dams easy. Access Panels for Maintenance: Built-in access points let you service electrical and drainage without removing the ceiling system.

Dry Space/Waterproofing FAQs

The Dry Space/Waterproofing system creates a moisture-controlled area, but it’s not the same as a conditioned or insulated interior space. If you want to enclose the space fully as a finished room, additional framing, insulation, and permitting would be required. We can evaluate your goals and recommend the right solution during your consultation.
Minimal maintenance is needed. We recommend seasonal checks to remove leaves from drain covers and ensure downspouts remain clear. If your system includes access panels, you’ll be able to inspect and maintain them with ease.
Most installations are completed in 2 to 4 days, depending on the size of the deck, weather conditions, and any custom features like lighting or ceiling fans. We’ll provide a detailed schedule after your design is approved.
