A Guide to Building Dryers

Our vast range of building dryers are perfectly suited for use in the demanding environments such as building sites and hire fleets. Designed specifically to provide rapid drying solutions and humidity control, a building dryer can decrease drying times by up to 40%.
 

How to tell when Building Drying is complete

 
The British Damage Management Association (BDMA) defines building drying as complete when:

  1. The internal conditions of the property are at, or better than normal room conditions
  2. The moisture on and in the building materials themselves will not support active growth of toxic mould (mold), mould (mold) and mildew as a result of the incident of flood damage that has most recently occurred
  3. The building materials and contents will return to equilibrium with normal room conditions by themselves, without further damage.
 

Drying and Energy with Building Dryers

 
Water, as it evaporates, absorbs heat, cooling the material it evaporates from.

Two important points to remember are that evaporation inevitably cools the material that loses the water and that the rate of evaporation reduces as the temperature falls. In a laboratory it is possible to evaporate water so quickly from a brick that the water still contained in it freezes and evaporation comes to a virtual halt until the brick warms up again. It is not uncommon on walking into a recently finished new building to find that it is noticeably cooler than the air outside. This is the result of the materials drying out.

The heat energy taken to evaporate five litres of water is at least 3.6kw for one hour.

Richfords are equipped with new super heating dehumidifiers which can rapidly carry out building drying by replacing the heat loss through evaporation.
 

Considerations before drying a building

 

  • Can the building be sealed?
  • Is the building's heating and/or air conditioning system available?
  • What is the condition of the property's electrical system?
  • What types of material are being dried?
  • How long were the materials under water?
  • What was the depth of water saturation?
  • What type of equipment can be used in this property for the drying process? What are the outside weather conditions?
  • What is the attitude and level of cooperation of the insured and building occupants?
  • What is the responsiveness of the insurance representative and/or property manager?
  • What is the overall condition of the fabric of the property?
  • Is the property at risk of re-flooding?
  • Is there any trapped interstitial moisture - moisture trapped in insulated floors and walls etc?
