Water damage – drying techniques


We build our homes from many different materials. Some of them are more and some less resistant to water damage. Now we know much more about the characteristics of these materials and can employ different methods of restoration and repair. Here we will tell you a bit about ways to dry out the parts of your house which have been affected by water damage.

What determines which method to use?

The first question we have ahead of ourselves when faced with water damage is should we dry or not? If the wet material is too far gone, meaning it has sustained very grave damage and cannot be returned to the previous state, then it should be discarded. The key factors which influence this are contamination, damage and, of course, cost.

If the material we are trying to rescue is so contaminated that it can be labeled as category 3 water damage, all of our efforts to repair it are meaningless. This material cannot be revived, so to speak, and cannot be returned to the initial state. It is best to dispose of it.


Furthermore, if the material has sustained so much damage that there is no way for an economically sensible repair, getting rid of it is the best solution. Drying these items or materials will not produce a positive effect. Finally, if the repair is possible, but it comes at a cost so great that it exceeds buying a new item, drying the item is simply not economically reasonable.

 Drying methods

Airflow, Temperature, humidity control – these are all crucial when drying water exposed items and materials. Drying methods revolve around combinations of these. However, there are two basic and most common methods of drying – disruptive drying and aggressive drying.

Disruptive methods are based on perforating surfaces. It allows any water trapped inside the material to evaporate. Air is also injected so that the drying process is much faster. Wet items are usually removed.

Aggressive methods which are also known as « in place » methods are based on direct airflow of dry, warm air. Wet items are inside the building where they were affected by the water and then dried using powerful heaters and fans. This method is in use when damage is not too great, and the costs of drying do not exceed the cost of the damaged items.
