Water Damage Restoration Water Damage Knowledge 4

Question 1

What does GPP (grains per pound) measure in the context of water damage drying?

Accepted Answer

The amount of water vapor present in a pound of air

Answer

GPP quantifies moisture content of air; tracking GPP decline confirms the structure is drying toward target conditions.

Question 2

Which of the following is the BEST indicator that structural drying is complete?

Accepted Answer

Moisture readings have reached pre-loss or reference levels on all affected materials

Answer

Drying is complete only when all affected materials return to baseline moisture levels, not just when visible signs disappear.

Question 3

A bathroom supply line burst while the homeowner was on vacation for 5 days. What water category and class should the restorer assign?

Accepted Answer

Category 2 or 3 (degraded clean water) and Class 3 or 4 depending on saturation depth

Answer

Clean water degrades over time due to microbial growth, so after 5 days it is likely Category 2 or 3; class depends on how deep moisture has penetrated.

Question 4

What is 'controlled demolition' in water damage restoration?

Accepted Answer

Selectively removing damaged materials to allow drying of concealed cavities

Answer

Controlled demolition involves removing only the necessary building components (e.g., drywall flood cuts) to expose and dry hidden wet cavities.

Question 5

What is the IICRC-defined purpose of documentation during a water damage restoration project?

Accepted Answer

To provide a record of conditions, actions taken, and drying progress for liability and billing purposes

Answer

Thorough documentation protects the restorer legally, justifies billing to insurers, and provides proof that work met professional standards.
