device and saett foer drying in a building existing water damaged floors or golvunderlag of concrete

摘要

There is proposed a method for drying a water-damage concrete floor structure or concrete sub-floor (3), which may or may not include an insulating layer (4, 2). According to the invention, an insulating device (7) is placed on the floor surface in spaced relationship therewith so as to form an underlying gap (8). Dry, hot pressurized air is delivered to the gap with the intention of removing moisture-laden air that has diffused up from the water-damaged area. When the sub-floor supports an insulating layer (4) of sand or mineral wool, hot, dry air is also delivered to this layer. The invention also relates to apparatus which operates in accordance with the inventive method.
