Method and arrangement for drying a water damaged floor structure

Abstract

A method and arrangement for drying a water damaged floor structure having a ventilated isolating layer below a concrete layer extending throughout an enclosed space, and the enclosed space having a tiled flooring over the concrete layer. An outlet opening is provided into the floor structure and to the isolating layer outside of an end of the enclosed space, the tiled flooring is heated by a heating source, and ambient air drawn by a suction source through the isolating layer and out of the outlet opening.

1 . A method of drying a water damaged floor structure having a ventilated isolating layer below a concrete layer extending throughout an enclosed space, and the enclosed space having a tiled flooring over the concrete layer, characterized by providing an outlet opening into the floor structure and to the isolating layer outside of an end of the enclosed space, heating the tiled flooring, and drawing ambient air through the isolating layer and out of the outlet opening. 
     
     
         2 . The method of  claim 1 , comprising covering the tiled flooring being heated by a heat insulated flexible layer. 
     
     
         3 . The method of  claim 2 , comprising providing said heating by forcing hot air between the flexible layer and the tiled flooring. 
     
     
         4 . The method of  claim 1 , comprising providing also an inlet opening for the ambient air into the floor structure and to the isolating layer outside of a second end of the enclosed space. 
     
     
         5 . The method of  claim 1 , comprising drawing the ambient air through the isolating layer via a hollow perforated pipe driven into the isolating layer. 
     
     
         6 . The method of  claim 5 , comprising driving the hollow perforated pipe by rotating the hollow perforated pipe having a helical external thread. 
     
     
         7 . An arrangement for drying a water damaged floor structure having a ventilated isolating layer below a concrete layer extending throughout an enclosed space, and the enclosed space having a tiled flooring over the concrete layer, characterized by an outlet opening into the floor structure and to the isolating layer outside an end of the enclosed space, a heating source for heating the tiled flooring, and a suction source for drawing ambient air through the isolating layer and out of the outlet opening. 
     
     
         8 . The arrangement of  claim 7 , comprising a heat insulated flexible layer for covering the tiled flooring being heated. 
     
     
         9 . The arrangement of  claim 8 , wherein the heating source is in or below the flexible layer. 
     
     
         10 . The arrangement of  claim 8 , wherein the heating source comprises a hot air source capable of forcing heated air through hot air tubing into a space defined between the heat insulated flexible layer and the tiled flooring. 
     
     
         11 . The arrangement of  claim 7 , comprising an inlet opening for the ambient air into the floor structure and to the isolating layer outside of a second end of the enclosed space. 
     
     
         12 . The arrangement of  claim 7 , comprising a hollow perforated pipe to be driven into the isolating layer for drawing the ambient air through the isolating layer. 
     
     
         13 . The arrangement of  claim 12 , wherein the hollow perforated pipe has a helical external thread for the pipe to be driven by rotational movement. 
     
     
         14 . The arrangement of  claim 12 , wherein the hollow perforated pipe is flexible. 
     
     
         15 . The arrangement of  claim 10 , wherein the suction source is a suction blower and the hot air source is a dehumidifier. 
     
     
         16 . The arrangement of  claim 15 , wherein the suction blower and the dehumidifier are serially interconnected. 
     
     
         17 . The arrangement of  claim 16 , wherein the suction blower and the dehumidifier are arranged in a common sound and heat insulated casing having a sound and heat insulation.
