Carpet The primary goal in water damages is to preserve and protect the structure and contents.  One of the first concerns is water-saturated carpet and padding, where unique problems are encountered. The vast majority of the carpets are tufted construction type.  In simple terms, the tufting mac...

Here are some other terms you should get accustomed to... Dew Point    The temperature at which water vapor begins to condense is known as the dew piont.  When air is saturated with water vapor, a drop in temperature forces the air mass to release some of its moisture in the form of condensation....

   Psychrometry is the study of the air and its properties.  The properties of temperature, humidity, vapor pressure and dew point are measured to evaluate air conditions and determine whether intervention is needed to prevent damage to materials.  Psychrometrics (another name for "psychrometry")...

   Water-damaged structures and the restoration process create numerous slip, trip and fall hazards.  Wet surfaces are normally slick, and equipment hoses and power cords provide ample opportunity for workers and occupants to slip, trip or fall.  Post warning signs and brief occupants about the h...
