Structural Drying Standards: The Science Behind Professional Moisture Removal That Protects Your Property
When water damage strikes your home or business, the visible flooding is only the beginning of your concerns. What happens next—the professional structural drying process—determines whether your property will be fully restored or face costly secondary damage like mold growth and structural deterioration. Understanding how professionals ensure complete moisture removal through established industry standards can help property owners make informed decisions during one of the most stressful times they’ll face.
What Are Structural Drying Standards?
IICRC Standards are internationally recognized, ANSI-accredited guidelines that define best practices for inspection, cleaning, and restoration work. They are developed through rigorous consensus processes with industry input, and they serve as the foundation for training, certification, legal reference, and everyday field practice. The IICRC sets industry standards for water damage and mold remediation. Through research, laboratory testing, and field experience, the IICRC has identified three principle components for successfully drying a structure.
Structural drying is the removal of excessive, trapped moisture from building materials (both structural and non-structural) in an efficient amount of time. The process goes far beyond simply removing standing water—it requires a scientific approach to ensure that moisture hidden within walls, floors, and other building materials is completely eliminated.
The Four Critical Phases of Professional Structural Drying
Professional restoration companies follow a systematic approach based on established standards to ensure thorough moisture removal:
1. Water Extraction Phase
There are three ways of removing water from a structure; physical extraction, dehumidification, and evaporation. Removal of liquid water is at least 500 times more efficient than just going straight to using dehumidifiers and air movers. The more water that can be extracted, the quicker the structure will dry. This initial phase is crucial because it sets the foundation for all subsequent drying efforts.
2. Air Movement and Evaporation
Promoting air circulation is crucial for efficient drying. Industrial-strength air movers are strategically placed to enhance the evaporation of moisture from surfaces. Proper air circulation ensures that damp air is continuously replaced with drier air. Professionals typically try to stay within the 75-to-90-degree range to accelerate the evaporation process and release moisture from building materials.
3. Dehumidification
As the moisture is forced into the air, it evaporates and becomes water vapor in the air. Dehumidifiers are used to absorb moisture from the air. It is essential to use dehumidification; otherwise, absorbent materials in the room could soak up the moisture and become damaged. Professional-grade dehumidifiers are specifically designed for water damage restoration scenarios and can operate effectively in high-moisture environments.
4. Monitoring and Documentation
Throughout the drying process, professionals use moisture meters and other monitoring tools to assess the progress. After the initial drying process, moisture testing is conducted to ensure that the affected materials have reached an acceptable level of dryness. This involves using moisture meters and other testing equipment to measure moisture content.
Establishing Dry Standards: How Professionals Define “Dry”
One of the most critical aspects of professional structural drying is determining when materials are actually dry. The Institute of Inspection Cleaning and Restoration Certification (IICRC) gives definition to this what is called acceptable with the term “dry-standard or dry-goal.” The definitions section of the IICRC S500 current edition describes dry-standard: “a reasonable approximation of the moisture content or level of a material prior to a water intrusion.”
The IICRC-S500 says that no matter what equilibrium moisture content (EMC) you get from the materials in the structure, you cannot leave material at an EMC that would support microbial growth. It also says that an acceptable dry standard is within 10% of what the other similar materials in the facilities were pre-loss. This scientific approach ensures that materials are not just superficially dry, but thoroughly dried to levels that prevent future problems.
Advanced Equipment and Technology
Professional structural drying relies on sophisticated equipment that goes far beyond household fans and dehumidifiers. These are some of the tools professionals use to measure, monitor, and evaluate during the drying process of a structure: Moisture sensor – senses moisture in materials over 17% MC; helps determine perimeter of water damage; unable to determine which layer is wet or when dry; Thermo-hygrometer – determines temperature/RH in all required atmospheric areas of inspection; helps determine open or closed drying system; further determines dehumidifier requirements after initial placement; Moisture meters – invasive and non-invasive; determines moisture content; establishes, monitors, and determines progress throughout the drying process.
Different types of dehumidifiers are used depending on the specific conditions. Refrigerants perform most efficiently in operating conditions 70° – 90° F. It is usually the most efficient dehumidifier to use in warm, wet environments. LGR – Low-grain refrigerant dehumidifiers – This kind of dehumidifier removes water vapor from the air using a process called condensation.
The Importance of Professional Expertise
While there are some DIY techniques for addressing minor water damage, professional structural drying is highly recommended for significant incidents. Professionals have the expertise, specialized equipment, and resources to ensure thorough and efficient water removal. Additionally, DIY efforts may fall short in addressing hidden moisture pockets or preventing secondary issues such as mold growth.

The Long-Term Benefits of Proper Structural Drying
Quick and efficient structural drying helps preserve the strength and stability of the affected structure. Water damage can lead to secondary issues such as warped floors, stained ceilings, and damaged belongings. The longer water remains, the greater the likelihood of secondary damage. Efficient drying minimizes these effects, reducing the scope of repairs and associated costs.
Excess moisture causes structural damage and creates an environment where mold can thrive. That’s why structural drying and moisture control are critical to restoring your property and maintaining its integrity. Professional restoration companies understand that their work doesn’t end when the equipment is removed—it ends when the property has been verified as completely dry according to industry standards.
Conclusion
Structural drying standards represent the culmination of decades of research, field experience, and scientific understanding of how moisture behaves in building materials. Advanced Structural Drying (ASD), based on psychrometry, science, and mathematical formulas, is a proven method to accelerate drying, reducing costs, time, and inconvenience related to replacement and repairs. While this technique may initially involve more equipment than standard drying processes, it can produce results that get homeowners back in homes faster, businesses back open, and salvage materials that would have previously been expected to need removal and replacement.
When water damage occurs, the difference between a quick cleanup and a complete restoration lies in following established structural drying standards. Professional restoration companies that adhere to IICRC guidelines and use advanced equipment and monitoring techniques ensure that your property is not just visibly dry, but scientifically verified as completely moisture-free, protecting your investment for years to come.
