Following severe saturation to ground floor bedroom, conventional drying equipment was installed (large dehumidifier and fans) to dry out the walls and floor.
After one week, there had been no significant change in WME or ERH, it was at this stage that the DAD was installed.
Date of installation— 15/06/04
During the following week, 3 monitoring visits were carried out and ERH measured with the following results:
If the D.A.D. had not been installed, we would have anticipated the drying process to have taken a further 2—3 weeks to reach acceptable levels.
Leak from ice machine behind bar went unnoticed and ran under solid wooden flooring causing severe distortion to flooring and saturation to screeded sub-floor.
Following uplifting of wooden flooring, we were advised that there was a limited timescale to dry out the affected area. Due to the different sizes of beds used with the system, we were able to install the system to the affected area only causing minimum disruption to business.
Date of installation—26/07/04
03/08/04 —ERH— 70%
As we were able to concentrate drying on affected area only, the ERH levels were reduced drastically, enabling new flooring to be laid on time.

Following torrential rainfall, overflowing drains caused water to run down the lane where property is located and through doors flooding areas of the ground floor. The large kitchen has wooden floorboards with a void underneath (approximately 6-8 inches deep), water went under the floor into void causing severe saturation of joists, underside of floorboards and ground below. To install normal equipment, would have meant uplifting a large area of the flooring, rendering floor unrestorable. As insurers wanted to try to save the flooring, it was decided to install the D.A.D. system, This was done by uplifting just 2 boards on either side of the room, laying double sided mattresses in the void and inflating, enabling us to dry the underside of hoards, joists and ground below. Due to amount of airflow from double-sided mattresses, we were also confident of keeping any fungal growth to a minimum. Timescale for drying procedure was not a concern but saving wooden floorboards was, we feel that this was possible because of this system.
