What characterizes water intrusion class 1?

  1. Significant amount of water present

  2. About 5% of building materials are wet

  3. Deeply held or bound water

  4. Great evaporation load

The correct answer is: About 5% of building materials are wet

Water intrusion class 1 is characterized by the fact that only a small portion of the building materials, specifically about 5%, are wet. This classification indicates the least affected category, where water damage is minimal. In this scenario, there is no significant moisture present, allowing for a relatively straightforward restoration process. This classification is important as it helps restoration professionals assess the situation accurately and determine the appropriate response. Understanding this allows for prioritizing interventions based on the degree of water intrusion and its potential effects on the materials involved.
