• the present invention is intended to have its application in sealing of gaps, where the gap is to be defined by opposing surface portions or surface sections between two units or construction details, the one construction detail is to display said first surface section, faceable towards the other construction detail, while said other construction detail is to display a second surface sect- ion, faceable towards the first construction detail.
• the present invention also encompasses the utilisation of a hose portion, and to use this hose portion to form a hose arrangement, where this hose portion and hose arrangement, are to be adapted to be able to be used in said met- hod, disclosed according to the invention.
• the present invention is further based on the significant feature that said hose portion should be given a total length corresponding to or exceeding the length of the total length of the gap, or a part thereof, as well as a cross section and/or a cross sectional surface, corresponding to (equal to, larger than and/or smaller than) the actual width of the gap (the distance between opposing first and second surface sections).
• the hose portion and its hose sections, disclosed and used, according to the invention is principally to be of a formable structure, i.e. the material of the hose portion should more or less be foldable, but not necessarily elastically, in order to be actuable and formed to a less unfolded state by a supplied inner pressure.
• the material of the hose portion is chosen to be of an elastic structure, i.e. the material in the hose is to be more or less elastic and thus causing an expanded cross section by a supplied inner pressure, the cross- section will expand and its channel disposed inside the hose portion.
• the present invention principally relates to being able to offer a seal to gaps, slots etc. within the building industry and is intended to have its specific coordination as regards sealing in an air-tight and/or liquid-tight fashion of a gap between adjacent surface sections for neighbouring or adjacent oriented building modules, building elements and/or constructional details, it should be taken into account that the present invention may very well have an advanta- geous application in broadly different other embodiments, applications and application devices and/or construction details and/or units.
