Two Drying Methods
After making the decision of whether or not to dry a material, Project managers begin evaluating how to begin the restoration work. Many methods are available - each applying a different combination of humidity control, temperature, airflow and physical manipulation of the material (e.g., injection of airflow, perforation, removing finish materials).
Our Project Managers use the information obtained during evaluation of materials to help select the best drying method for the job. Generally there are two primary methods to promote drying of affected structures: 1) disruptive methods and 2) aggressive methods.
Disruptive Drying Methods
Disruptive drying methods involve removing wet items, injecting air to speed drying, or perforating surfaces to allow water to evaporate. The term disruptive is used because repairs will have to be done after the structure has been dried. Use disruptive methods when contamination, damage, cost or customer concerns require removal or manipulation of the affected material.
Aggressive Drying Methods
Aggressive or "in-place" drying methods involve leaving wet items in the structure and drying them in-place using warm, dry direct airflow. Aggressive methods are used when contamination and damage are not concerns, and when it is cost effective to dry an item instead of replacing it.
Project Managers will use aggressive drying methods when all of the following are true:
- The water intrusion came from a sanitary source (Category 1).
- Drying carpet and underlay (pad, cushion) in place will not cause structural damage to subfloor (especially hardwood).
- Adequate dehumidification is available and usable on site.
- Deep extraction tools are available.
The success of each decision made during the restorative drying process depends on the information upon which the decision was based. A skilled technician with quality meters will make the proper decision at each phase of the project.
