Structural Drying Eagle

Comprehensive structural drying removes the moisture that water damage leaves behind. It starts with using the specialized tools of the trade—moisture meters and infrared cameras—to assess how far the water has penetrated the structures and how much of it is still there. If the assessment is done well, the next step should require much less effort and time than if the opposite were true; that is, if the water damage were more extensive than first thought or if it had more time to spread before the drying process was initiated.The next step in the process is extraction. This is where the largely non-visual water is removed by pumps and vacuums so that what is left behind can actually dry. After the equipment is set up and the extraction process is complete, the next step is drying using a combination of industrial-strength dehumidifiers and air movers.

The restoration process that follows water damage is applied structural drying. In a normal situation where there is no water damage, the structure is relatively dry and the air inside it is somewhat humid. When a building is affected by water infiltration, its walls, floors, and other structural elements take in an excessive amount of moisture. This is bad for both the short-term and the long-term integrity of the structure, as well as for the people who occupy it and the places where they spend time.nnTo stop the intake of moisture from harming a structure and those in and near it, applied structural drying gets to work with equipment that pushes air into and around the moist parts of the structure. . . . Finally: the use of dehumidifiers to overcome excessive humidity that might otherwise prevent normal drying for a long time (or might cause mold to grow in the interim).

Structural drying comprises four distinct stages:1. Initial Water RemovalThis entails pulling water that is not in motion out of a space. Motors that use kinetic energy to move fluids and gas work best to achieve this. Indeed, all water removal (extraction) methods at NIST employ pumps and motors to move water with either a centrifugal or a linear flow pattern. To be sure, this method of moisture removal is widely used in various applications.2. EvaporationEmploying air movers and fans directs moisture from structural materials into the air, where it can evaporate much more rapidly than when it is confined to the structure. Using these tools effectively requires attention to airflow and energy transfer in the affected materials.3. DehumidificationUsing dehumidifiers to extract moisture from the air that will lower the humidity and dry the structures and their contents faster and more efficiently.4. Temperature ControlSetting the temperature with heaters or HVAC systems to create the best possible drying conditions. The right temperature helps dryer air accept more moisture; indeed, warm air holds more moisture than cold.

In structural drying, there are three primary methods of moisture removal: air drying, dehumidification, and heat drying.Increasing ventilation enhances evaporation during air drying. Specialized equipment removes moisture from the air during dehumidification. Heat drying means raising the temperature to speed the evaporation process.

In Eagle, structural drying works best using a medley of methods, which together efficiently eradicate moisture and prevent further incidents of water damage. The first method employs the use of high-capacity air movers to really amp up the air circulation in the damp, wet space. The next method couples that air movement with industrial-strength dehumidifiers, which expel the water vapor from the air. Next, along with using those two methods, it's really critical to the moisture monitoring process to use moisture meters to simply take note of how wet or dry the various monitored materials are. Finally, if it's available, using infrared technology to see moisture that you can't see with the naked eye really makes a comprehensive moisture search in the dried space. These four methods, if used properly together, should achieve a successful drying of the structure and contents.

Extraction is the first and most important drying phase in structural drying, where excess water is removed from the structure using vacuums and pumps. This initial phase reduces the overall moisture load and allows the other drying processes to go faster.

In Eagle, during structural drying, technicians first evaluate how much water has gotten into materials and how wet they are. They use pumps and vacuums to get out any water that isn't baked into the materials themselves. Then, they set up dehumidifiers and air movers to start pulling moisture out of the air and encourage evaporation in the materials. They may also set up some additional heat, drying mats, or other tools to assist in the process, depending on what's necessary for the job at hand. The techs involved in this part of the process don't work with the kind of moist-hair, half-baked judgments that the average person might when deciding whether to toss a musty book. They work moisture-level magic with the aids of air pressure, heat, and electrical power.

The most effective drying agent in structural drying is much more typically a mix of air movers and dehumidifiers. Air movers help increase air circulation, which helps in the drying process by causing the moisture to evaporate from the surfaces and not just the top layer of materials. Dehumidifiers remove a large amount of excess moisture from the air; otherwise, it would just hang around and make the place smell musty. Though some folks still use them, we get better results faster when drying structures with air moving machines and dehumidifiers.

Structural drying is best performed at temperatures between 70°F and 90°F. This range provides evaporation and dehumidification processes with optimal conditions to create an appearance of dryness. In other words, it enhances drying efficiency.

The 60-60 drying method is a technique used in structural drying to efficiently remove moisture from water-damaged areas. This method involves maintaining a temperature of around 60 degrees Fahrenheit and a relative humidity of about 60%. By controlling these environmental conditions, the drying process is optimized, helping to prevent mold growth and minimize structural damage. The method leverages the principles of psychrometry to enhance the evaporation rate and speed up the overall drying process.
