Title: BASE FLOOR OF A BUILDING AND A METHOD FOR CONSTRUCTION OF A BASE OF A BUILDING
Abstract:
The invention relates to a base floor of a building, which comprises a load bearing slab formed onto a compacted and levelled soil layer (50) or onto a hard thermal insulation layer (24) formed onto the surface of a compacted and levelled soil layer (50). The bearing slab comprises a first surface (16a) positioned against the soil layer or thermal insulation layer and a second surface (16b) at a distance from the first surface, with a thin sheet structure comprising air flow paths parallel to the first and second surface between the first and second surface. Air can thus flow along the flow paths between the first and second surface and exit from between the surfaces through apertures opening to the end edges and/or side edges of the base floor.
