Apparatus for constructing an annular wall, the apparatus comprising inner and outer forms having respective substantially upright form surfaces defining a mold cavity therebetween corresponding to a segment of the wall to be constructed. The forms are attached to a support assembly rotatable about a fixed pivot anchor located substantially at a central axis of the wall such that the support is rotatable about the axis in a substantially horizontal plane. The arrangement is such that, in use, the forms are positioned at a selected first angular location relative to the central axis and a concrete composition is filled into mold cavity to create a first wall segment, after which the form is moved by rotation about the pivot axis to an adjacent location whereat the concrete composition is filled into the mold cavity to create a second wall segment adjoining the first.
Apparatus for constructing a circular storage vessel on a preformed base, the apparatus comprising a molding form support structure with an adjustable length pivot arm that in use couples the support structure to a pivot anchor fixed to the base, inner and outer mold forms attachable to the support structure, the inner and outer mold forms defining, in use, a mold cavity corresponding to an annular wall segment, wherein the support structure has first and second sets of wheels capable of supporting the support structure on the base, the first and second sets of wheels being selectively engageable to enable respective orthogonal movements of the support structure relative to the pivot anchor.
