Summary:PROBLEM TO BE SOLVED: To provide a basic heat insulating drainage structure which uses the rock wool or the glass wool of a mat base that drains water in a short time even if covered with water by a typhoon, a flood or the like. SOLUTION: A sheet for drainage formed of nonwoven fabric or the like which is continuous from the lower part of the rock wool or the glass wool brought into contact with the mat foundation part covered with water to a crushed stone side below a footing is laid and water soaked in the rock wool or the glass wool of the mat foundation part is made to escape to the crushed stone side below the footing by a capillary phenomenon, so that drainage is carried out in a short time. A similar effect is obtained by piling up soil below the rock wool or the glass wool even if the base does not have the footing. COPYRIGHT: (C)2007,JPO&INPIT
