Drying and Dehumidification
After water has been extracted from water-damaged homes, the process of drying begins. Drying techniques are used to remove excess moisture that may have been absorbed by walls, floors, and other porous materials. Drying needs to be done fast and professional drying techniques must be applied to prevent any further damage and get the best results.
While an area is being dried and dehumidified, Rare Restoration & Cleaning will be constantly monitoring progress for moisture levels on walls, floors, and other surfaces. The cycle only stops when the area has been declared thoroughly dried.
The most commonly used drying techniques used by water damage restoration experts are:
To dry out a specific room, air moving equipment will be set up to promote air circulation and faster drying. Industrial air movers feature high-speed fans that allow much airflow across walls, floors, carpets, and furniture.
Dehumidification is a lot more thorough drying application as it uses portable machines called dehumidifiers that effectively removes all excess moisture from the air. When humidity is removed, the faster the process of drying inside water-damaged rooms or buildings. This is why dehumidifiers and air movers are often used together.
There are two common types of dehumidifiers:
Dehumidifiers that have cooled coil surfaces that condenses moisture in the air are classified under this type. Air moisture or water vapor are then trapped and collected, leaving dry air in the room that is ideal for the faster drying process. High-capacity refrigerant dehumidifiers can remove up to five gallons of vapor turned water in 24 hours.
Dehumidifying may also be done through the use of desiccants, materials that attract air moisture. Desiccant material absorb moisture onto their surfaces without undergoing any change.
There are also other drying techniques that are more complex and used for very specific applications. These include:
Freezer drying is a specially used for drying wet paper products. It’s a passive method where books, documents, and photos are placed inside a zip bag and letting them sit inside the freezer for several weeks. Temperatures are set to no less than -10 degrees Fahrenheit.
Vacuum Freeze Drying
Vacuum freeze drying is also a method used for drying paper, but in larger volumes as the equipment needed is relatively expensive. Paper items to be dried are frozen under vacuum conditions. The technique allows for sublimation, or the conversion of frozen water to vapor, without going to go through the liquid stage. This process prevents further paper damage or deterioration.
