Graeme Stephens, an IICRC-certified – 2001 Master Restoration Technician, offers this building drying information. Over 36 years of drying out timber framing, structural facilities, and construction sites in South Auckland, North Shore, East, West Auckland and Hibiscus Coast. Thus, to help you make an informed decision for drying your buildings at home or workplace.

Large dehumidification and blower fans can help dry buildings from excess water and avoid future black mould issues. Also, lowered relative humidity (RH) draws moisture towards the dryest point, the air, from materials used in construction building frameworks or water damage.

Excess Moisture Content In Building Structure Materials

Auckland Steam n Dry can restore emergency flood damage, provide carpet drying service, and sanitise disinfecting to maintain human health as essential safety services.

In water damage or excess moisture in the timber frame, the general rule is to apply dehumidification immediately. The flooded nature and extent of floodwater damage vary considerably. Indeed, it is necessary to assess the right approach, from timber framing buildings to structural construction. Steam n Dry Carpet Drying Auckland Services provides structure dry-out services, including a blower for hire and a large-capacity dehumidifier for rent.

Commercial Dehumidifier Rental

It would help keep air change low when drying out newly constructed structural buildings. Also, you often have to meet a deadline. Thus, it’s essential to have high-capacity equipment like the giant 90-litre-per-day Auckland Steam N Dry Commercial Dehumidifier Rentals. Before the Auckland Council pre-line framing moisture test inspections. Indeed, 24/7 emergency drying out timber framing building services.

For over three decades, our building dryers have been equipped. This includes Graeme Stephens, who is believed to be the most experienced flood-drying technician throughout Auckland. IICRC certified as Master Restoration Technician 2001. He provides all forms of building structure, drying out using powerful Auckland Steam N Dry air blower rentals and giant commercial dehumidifiers.

Drying Out Wood Frame Structural Buildings

Formerly, construction builders’ work on an average building lasted 6-9 months. When the structure was dried and finished, the timber framing building materials were dried out by natural ventilation. However, construction timber framing structural building work is very efficient and faster today. Dehumidification is required to remove the excess water in the various building materials before the Auckland Council pre-lines building moisture test inspection. The building can be safely re-occupied. Indeed, Steam n Dry Dehumidifier Rentals Auckland has provided structure dry-out services, including blower hire and large-capacity dehumidifier rental.

When hiring a dehumidifier for drying out a building structure, you need to consider how much water is removed and how much time you have to do it.

In some cases, estimating the water content in the wooden framing building materials is taken from tables. Please note that it all comes down to the specific building materials used for framing and, if applicable, walls, floors, and roofs. Also, the water content of various structural building materials differs so much that a simple rule of thumb needs to be fixed.

Drying Buildings Out Theory

The water content of different building materials (kg/m3)

Material          At The Start Of  The Project        Was Chemically Bound        At 50% Rh         Water For Dehumidification

Wood                                            80                                                0                                            40                                              40

Concrete lightweight                    90                                                0                                             20                                             130

Concrete Heavy                          150                                              70                                            50                                              60

Tile Roof                                       10                                                0                                             10                                               0

Brick Wall                                     80                                                0                                             10                                               70

In the above example, Auckland Steam n Dry wants to calculate the dehumidification required to effectively dry out excess water moisture from the structures of a newly constructed building in 30 days. The building is 2.8 m high, 8 m wide, and 18 m long. The floor, however, is to be dried out from 120 mm thick concrete.

The Building Volume Information:

Period                              30 Days

Drying RH                         Temp = 20°C and 50% RH (average between starting humidity at 60% RH and ending at approx. 40% RH)

Building M3                      2.8 m x 7 x 18 = 403.2 m3

Dehumidifier airflow      700 m3 per hour airflow

Air mover Blower            2800 m3 per hour airflow

Concrete            120mm

The Calculation:

Concrete volume for dehumidification:
18 x 8 * 0.12 = 17.28 m3

Water content on the concrete floor:
17.28 x 48 kg water/m3 = 829.44  kg water

We need to remove 829228 Litres of water in 30 days:
Water 829.44 @ 30 days = 27.64 Litres per 24 hours

We need a dehumidification capacity of 27.64 L/24 hours.

Recommendation:

30 Days. I am building structural drying out. Steam n Dry (SND) 80. Capacity: 1.40 litre/hour at 20°C @ 50% RH. One SND 80 will remove 32.8 L/24 hours. M that one SND 80 units dehumidifier rental should do the job in 30 days.

7-day building drying out. (SND) 80. Capacity: 1.40 litre/hour at 20°C @ 50% RH. One SND 80 will remove 32.8 L/24 hours. M that four SND 80 units dehumidifier hire should do the job in 7 days.

The flood drying process is quickest initially, as the water moisture content is high when you start the drying process. Then, when the RH value decreases, the overall dehumidification capacity will also decrease.

Drying Building Process

The dehumidifier runs continuously when using the dehumidifier to dry out building structures and materials. The relative humidity lowered, allowing further evaporation from the damp wooden framing building structures and materials in the room. The evaporation performance depends on the room, the elements, and the air’s humidity.

An advantage of condensed moisture drying is that the drying method is stable if time is not the primary dehumidification method. It maintains a permanent condition of 20°C and approximately 40% RH in the room.

Add artificial heat if necessary, but remember forcing the drying process might be harmful. There is a risk of surface drying and cavitation, with only surfaces dried, whereas humidity remains within cavities inside the wall.

Local branches in South Auckland, North Shore, East, West Auckland, Hibiscus Coast flood, and wood framing building dryers for over 36 years.

Drying Buildings Advice

Remember to seal the room or wooden frame building properly when empty. Also, remember to avoid pre-dried materials absorbing water because of open windows.

In most cases, the humidity is in areas where water is from external sources, such as rain. Before the building roof goes on, the building framing is sealed off, or the construction is ongoing.

The dehumidifier installation should be at these positions to do the best.
