What is the 'drying goal' in structural drying?
Answer: The target moisture content or relative humidity level indicating drying is complete
A drying goal is the specific moisture content or relative humidity target that materials must reach to be considered dry and safe from mold risk.
What is the purpose of drilling holes in walls during flood drying?
Answer: Allow air circulation to dry wall cavities
Drilling small holes at the base of walls allows air movers to circulate air into wall cavities where moisture is trapped, accelerating cavity drying.
What technique involves using plastic sheeting taped over drilled wall holes with an air mover attached?
Answer: Wall drying system (drying mat or injecti-dry system)
An injecti-dry or wall drying system uses plastic sheeting sealed over wall holes to direct concentrated airflow into wall cavities for efficient drying.
What is a 'flood cut' in structural drying?
Answer: Removing drywall up to a measured height above the water line to expose and dry wall cavities
A flood cut involves removing drywall to a height above the visible water line, typically 12-24 inches higher, to expose wet insulation and wall framing for drying.
How is the 'affected area' determined when setting up drying equipment after a flood?
Answer: Moisture readings and thermal imaging to map all wet materials beyond the visible water line
Moisture meters and thermal imaging cameras map all wet materials, which often extend beyond visibly affected areas due to wicking and migration through building assemblies.
What is the significance of monitoring 'vapor pressure differential' during structural drying?
Answer: It indicates the driving force moving moisture from wet materials into the air
Vapor pressure differential is the difference in moisture pressure between wet materials and the surrounding air, which drives evaporation and drying efficiency.
