A method of progressively constructing a wall of cementitious material, including the steps of supporting a formwork support structure on a lower foundation, or completed wall section, by means of hydraulic jacks each including a hydraulic ram assembly carrying the formwork support structure and adapted to climb up a vertically extending jack tube, raising said formwork support structure by said jacks to a higher pouring position, supporting said formwork support structure on the lower foundation, or wall section, by auxiliary support means, raising the jack tubes for each jack through its associated ram assembly, moving a formwork section on the outside of the wall toward a formwork section on the inside of said wall to provide a cavity for the receipt of cementitious material, pouring a quantity of said material into said space between said formwork sections, the lower foundation, or completed wall section, and the lower ends of the jack tubes, allowing said cementitious material to solidify, and moving the outer formwork section away from the wall and disengaging the inner formwork section, with said formwork support structure being supported on said jacks.
