PortalWall® DSEC™ (Dry Side Enabling Component)
U.S. Patent No. 10,329,758 B2 — Claim #17 (Novel Use and Unexpected Results)
Product Overview & Field Deployment
The PortalWall® DSEC™ (Dry-Side Enabling Component™) is a deployable structural support that replaces conventional metal studs with a specialized configuration engineered to reduce condensation and mold risk within the wall assembly.
Working as the core structural framework of the PortalWall® DSEC™ (Dry Side Enabling Component), it isolates structural connections strictly to the dry side of the wall plane.
Field-Ready Drop-In Replacement: DSEC™ can be introduced wherever framed walls and sheetrock—or comparable interior finishes—are specified, without requiring architectural or structural redesign.
Flexible Attachment: Can be mounted directly on top of the slab or configured to bypass the slab. Engineered load tables are available upon request.
Immediate Integration: Fits directly into active construction projects and operates effectively with or without forced/engineered airflow.
Proven Physics: It is not speculative, nor does it require ground-up adoption—it is a practical, field-ready component designed for immediate installation.
The Client Question
"Basements face both ongoing daily moisture challenges—like high humidity and hydrostatic ground pressure—and extreme events like flash flooding or storm surge. How does the PortalWall® DSEC™ protect a basement during normal daily use and in the aftermath of a major flood?"
The Bottom Line Answer
The PortalWall® DSEC™ handles both conditions with a single mechanism: open-web thermodynamic physics.
Traditional basement construction tries to seal out environmental stress by stuffing layers of porous, organic insulation into tight cavities. During daily use, this disrupts the natural dew point, trapping moisture between cold foundation walls and interior finishes to breed hidden mold. During a flood, these same closed cavities act as sponges, holding gallons of water and forcing complete structural teardown.
Patented by Yonatan Margalit (U.S. Patent No. 10,329,758 B2), the PortalWall® DSEC™ replaces static, moisture-trapping barriers with an open structural framework (>50% open web). In daily operation, it washes the wall with ambient room air to evaporate micro-condensation naturally. In a flood event, it allows bulk water to drain away instantly while providing the open pathways needed to dry the structure in place—without tearing out your walls.
4 Core Performance Pillars: Baseline Living vs. Post-Flood Survival
1. Air Washing vs. Water Lock
Baseline Operation: Standard insulation pressed against cold concrete shifts the dew point inward, causing hidden, continuous condensation. The DSEC™ uses aperture portals with a >50% open web design to allow interior ambient air to wash continuously across the cavity, equalizing vapor pressure and drying out condensation before liquid droplets form.
Post-Flood Event: Standard bottom plates and closed stud bays trap standing water. The open-web profile of the DSEC™ contains no horizontal "water troughs," allowing bulk floodwater to drain down to relief points instantly under gravity.
2. Dry-Side Structural Backbone
Baseline Operation: Conventional steel or wood studs sit directly against damp foundation walls, absorbing moisture, rusting, or rotting over time. Driven by DSSS™ logic, all structural connections remain strictly on the dry side of the assembly, finished with heavy protective coatings to remain immune to high ambient relative humidity.
Post-Flood Event: Instead of absorbing floodwater, the non-hygroscopic, coated structural frame allows the wall assembly to maintain its structural integrity during and immediately following total water submersion.
3. Eliminating Organic Food Sources
Baseline Operation: Combining damp basement conditions with organic materials (fiberglass batt, paper-backed drywall, raw wood studs) guarantees mold growth. The DSEC™ pairs an open structural grid with inorganic, moisture-impervious infill panels, permanently eliminating the food sources mold needs to colonize.
Post-Flood Event: Because the assembly contains no organic "sponges," floodwaters cannot saturate the core. The wall does not harbor stagnant biological growth after water recedes.
4. The Freed-Air™ Dynamic: Active Recovery Without Demolition
Baseline Operation: Daily air circulation through the cavity keeps relative humidity balanced, preserving Water Vapor Aloft™ (WVA™) in the living zone without letting vapor collapse into hidden pockets.
Post-Flood Event: Rather than cutting out 4 feet of soaked drywall, pulling out ruined insulation, and rebuilding the wall, the DSEC™ enables simple post-flood recovery: wash down, sanitize, and run dehumidification/ventilation to air-dry the open assembly in place.
Salesperson Summary Close
"Whether facing 80% baseline summer humidity or 3 feet of storm surge during an extreme weather event, traditional basement wall methods fail because they trap moisture.
Incorporating the PortalWall® DSEC™ (Dry Side Enabling Component)—patented under U.S. Patent No. 10,329,758 B2—stops fighting building physics. Its >50% open-web design continuously washes the interior cavity with ambient air to manage daily humidity, while providing the unobstructed drainage and ventilation needed for zero-demolition flood recovery. It protects interior finishes, eliminates liability, and transforms high-risk lower levels into resilient, code-compliant living spaces."
