Abstract (en)

A method for casting concrete or concrete like elements where said elements may have an amorphous shape, comprises the initial step of providing a mould, comprising a bottom surface (10') and side surfaces (20'), wherein the bottom surface (10') is an adjusted surface (10') having the curvature of the front surface of the concrete or concrete like element to be casted. Then molten wax (32) is poured into the mould. After solidification of the wax (32) a solid wax formwork element (30) has been formed, which can be mounted on a construction site into an outer load bearing support structure (40) creating a cavity of the concrete or concrete like element to be casted. After having poured fresh concrete or other concrete like material into the cavity, the concrete or other concrete like material is cured and the outer load bearing support structure (40) as well as the solid wax formwork element (30) are removed. Then the material of the solid wax formwork element (30) can be directly reused for providing molten wax (32) within the creation of a further solid wax formwork element (30).
