Structural Drying >> Dehumidification

The influenced mechanisms of the structure’s main electrical and HVAC systems must be Dehumidification and decontaminated. Division of the influenced area from the uninfluenced areas must be re-created if necessitated preceeding to tear-out. Once achieved, machine-driven drying could begin. These expenses might be entered in flood insurance claims approximation by one of the following processes: Square foot (SF) payment, is when rented tools or professional amenities are not concerned.
 
  1. An insurance payment to dry could be contemplated. Such payment would signify the usage and expenses of operating the HVAC system beyond the normal seasonal use and for industrial fans, commercial Dehumidification or space heaters the insured might use. Sensible alterations must be used if drying non-living spaces or areas of a structure with no climate change. When drying amenities are completed and the compliance of an itemized invoice is not reinforced with an appropriately finished drying report, understanding for the time, kind, and number of tools must follow these suggestions once a sensible try to confirm the quantity and kind of tools is made: Interval – Dehumidification must be accomplished for 1, 2, or 3 days based on the amount of wetness at the beginning of drying.
  2. Think about the following issues: The amount of time flood water stayed inside the structure. The sensible amount of unsalvageable objects stayed installed; and the amount of time after the elimination of unsalvageable structure items, structure clean-up and Dehumidification was achieved, to the start of machine-driven drying. Dehumidifiers – volume is based on the amount of objects soaked by trapped water. In environment -controlled spaces, the following procedures must be used with the particular Dehumidification type in order to decide on the quantity of dehumidification volume necessary. Low Grain Refrigerant (LGR) unit: volume of the influenced area in cubic feet ÷ 50 = the necessitated AHAM pints.
  3. Desiccant unit: volume of the influenced area in cubic feet ÷ 60 x 2 =necessitated CFM. When both kinds of dehumidifiers are used in the same influenced area, the collective volume of all the units must not surpass the volume decided of one procedure. Typical or regular refrigerant units must not be contemplated. Environment control, in an unfinished basement or cellar, dehumidification volume must be decreased. For areas of a structure subjected to soil or outdoor conditions, like in, crawlspaces, enclosed garages, or enclosed utility and storage rooms, Dehumidification must not be contemplated.
  4. Ducting might be used with desiccant units. The amount of air movers on day one must be based on the following: Lapsed time concerning the accomplishment of structure tear-out, thorough cleaning and disinfecting, to the beginning of machine-driven drying. Occurrence of affected salvageable material: Unprotected border wall covering, one air mover per 16 LF, Able to save floors, at least one fan per water damaged room or closet. With inside wall detachment: the elimination of the one fan per room or closet, needs a greater importance on the volume of air circulation and the total amount of the influenced area when drying the Dehumidification.
