TL;DR
A Class 1 water loss is the lowest evaporation-load category in the IICRC S500 drying standard, where water has touched only part of a room and soaked into few porous materials. Think of a slow supply-line drip caught quickly on a concrete or tile floor with minimal carpet or drywall wicking.
What it means
A Class 1 water loss is the lowest evaporation-load category in the IICRC S500 drying standard, where water has touched only part of a room and soaked into few porous materials. Think of a slow supply-line drip caught quickly on a concrete or tile floor with minimal carpet or drywall wicking. Because little moisture is bound in the structure, restorers can dry it with a small number of air movers and a dehumidifier, and the equipment count on the invoice should reflect that.
