What type of damage can hygroscopic materials face due to high humidity?

Hygroscopic materials are those that have the ability to absorb moisture from the air. When exposed to high humidity, these materials can absorb excess moisture, leading to changes in their physical and chemical properties. This phenomenon often results in secondary damage, which refers to the long-term effects that can occur after the initial exposure to moisture.

In the context of water damage and drying, secondary damage can manifest in several ways, including mold growth, warping, delamination, and deterioration of the material itself. For example, wood may become warped or swollen, while drywall can become soft and may lose structural integrity if not properly dried. This type of damage is not immediately visible but can lead to more serious issues over time if the materials are not adequately managed.

Other options don't capture the full impact of high humidity on hygroscopic materials. Mechanical failure typically refers to the immediate loss of structural integrity, while primary damage pertains to immediate harm caused by direct contact with liquid water, rather than moisture in the air. Uplifting of surfaces, while it could occur in some situations, is a specific occurrence rather than a broad category of damage that would be expected from high humidity. Therefore, secondary damage correctly identifies the complex and often delayed repercussions of moisture absorption in hygroscopic materials
