Structural Drying San Antonio TX | IICRC Certified
Structural drying is the science and engineering of removing moisture from within building materials — not just from surfaces. This distinction is critical and not well understood by homeowners. When water penetrates drywall, wood framing, insulation, and subfloor assemblies, the moisture content of these materials rises significantly above normal levels. Simply creating airflow at the surface — with fans, open windows, or household dehumidifiers — has virtually no effect on moisture trapped inside materials that are inches thick. Professional structural drying is the only reliable method for returning building materials to safe moisture levels.
Rhino Restoration uses industrial-grade LGR (Low Grain Refrigerant) dehumidifiers and commercial-grade air movers calibrated specifically for structural drying applications. LGR dehumidifiers can remove far more moisture per day than consumer-grade units, and commercial air movers create the high-velocity airflow at material surfaces required to drive evaporation from within the material — not just at the surface.
Our drying technicians monitor moisture levels daily using calibrated moisture meters and thermal imaging cameras, tracking the moisture content of each affected material type and adjusting equipment placement to optimize drying efficiency. This data-driven approach ensures your structure reaches safe moisture levels — below 16 percent moisture content for wood, and comparable levels for other materials — in the minimum time possible. All monitoring data is recorded and provided for insurance documentation.

Frequently Asked Questions
Why can't I just use fans and household dehumidifiers?
Consumer fans move air at the surface but cannot create the high-velocity airflow at the material surface required to drive internal evaporation. Consumer dehumidifiers typically remove 30 to 70 pints of water per day — professional LGR units remove 150 to 250 pints per day. More importantly, consumer units are not sized or positioned using psychrometric calculations, so drying is not systematic and materials are often left at elevated moisture content.
How do you know when structural drying is complete?
Drying is complete when all affected structural materials reach moisture content levels within the normal range for that material type in the local climate — typically below 16 percent for wood, and equivalent levels for other materials. We verify this with calibrated moisture meters at multiple points in each affected material before removing equipment.
Will I need to tear out drywall and flooring?
Not necessarily. In many cases — particularly when drying begins promptly within the first 24 to 48 hours — drywall and flooring can be dried in place without demolition. We use injectidry systems that can dry inside wall cavities and under flooring without cutting. In cases where drying is delayed or materials are already saturated beyond recovery thresholds, selective demolition is required.
Does structural drying prevent mold?
Yes — when initiated within the IICRC's 48-hour critical window and executed properly, professional structural drying prevents mold colonization in the vast majority of cases. Mold requires moisture content above approximately 60 percent relative humidity at the material surface to germinate. Proper drying keeps materials below this threshold.
