Drying techniques for properties following flood damage and escape of water

Drying out a property following a flood or an escape of water can be one of the hardest parts of the flood damage restoration process.

There are many different ways that you can dry out a property.

The drying technique you use will affect how long the process takes and the amount of remedial work required once dry.

To choose the best drying process for your property, a specialist in water damage restoration will take into consideration a number of things including:

  1. How long the property has been underwater for
  2. The source of water
  3. The type of building affected, and
  4. how quickly it needs to be restored to its pre-flooded state.

Suction drying for cleaning up after flooding

Where flood damage to a property isn’t extensive, suction drying can be a simple but effective means of drying out easily accessed water and damp.

However, whilst it’s both efficient and cost-effective, it has limited effectiveness where water has seeped below the flooring layers into voids and difficult to reach places.

With suction drying, air pressures within a room are used to force dry air down into the flooring through gaps or drilled holes. It’s a longer process than pressure drying but leaves fewer particles of dust and fibres in the environment, which can be really useful for allergy sufferers.

Injection drying for flood-damaged properties

Where the sub-floor may have experienced flood damage, such as where flood water has seeped into insulation laid beneath the flooring, it may be necessary to use injection drying to ensure moisture is effectively and thoroughly extracted.

Injection drying involves creating inlet and outlet holes and injecting warm air beneath the sub-floor. As this warm air escapes through the outlet holes, it removes with it the excess moisture, usually into a desiccant unit.

Moisture flush drying following flood damage or an escape of water

Reserved for buildings that have suffered extensive water damage, moisture flush drying is a fairly unobtrusive way of drying out a property.

By drawing air in from outside and heating it to 45°C, it draws the moisture out of the building and into the air, exhausting it from the property using a controlled venting system.

Supportive drying

This is a more sensitive form of drying properties flood damage or an escape of water which supports conventional drying methods. It involves a small, lightweight air exchange system, placed inside of the property. The heat exchangers strategically placed within the contained flooded area which speed up standard dehumidification processes in a water damaged property.
