From a static point of view, tent systems generally have to be fitted with bar fittings. But this is not always possible due to the value of the soil or due to supply lines laid in the soil. This is why we have used technical perfection to develop a ballasting system which makes customary bar fitting completely superfluous - actually and statically flawless. Damage in the base is completely avoided by use of this system. This system disappears invisibly UNDER the floor, with the result that no visual impairments of the tent system from the outside come about.
