The invention claimed is: 1. A method of producing a structure, in which: juxtaposing building elements so as to define a space between said building elements; mixing a joint compound composition with water so as to obtain a joint compound; filing said space with said joint compound composition, without using a tape; and leaving said joint compound to harden, wherein said joint compound composition comprises: a) 50 to 60 wt % of calcium sulphate hemihydrate; b) 5 to 15 wt % of an organic binder in powder form; and c) 0.05 to 0.2 wt % of a water repellent selected from the group consisting of oleic acid, stearic acid and their alkali metal or alkaline-earth metal salts. 2. The method according to claim 1, wherein the building elements are plasterboards coated with a paper facing. 3. The method according to claim 1, wherein the joint compound composition further includes: d) 1 to 10 wt % of a lightening agent. 4. The method according to claim 1, wherein the joint compound composition comprises 5 to 10 wt % of the organic binder; 0.07 to 0.15 wt % of the water repellent; and 3 to 7 wt % of a lightening agent. 5. The method according to claim 1, wherein in the joint compound composition the calcium sulphate hemihydrate is of the alpha type. 6. The method according to claim 1, wherein in the joint compound composition the organic binder is selected from the group consisting of copolymers of vinyl esters and of ethylene monomers, polyacrylics, vinyl acetate/acrylic copolymers, styrene/acrylic and styrene/butadiene copolymers, vinyl acetate/vinyl versatate/acrylic and vinyl acetate/vinyl versatate/vinyl maleate terpolymers, acrylic terpolymers and blends thereof. 7. The method according to claim 3, wherein in the joint compound composition the lightening agent is perlite. 8. The method according to claim 3, wherein in the joint compound composition the lightening agent is non-water-repellent expanded perlite. 9. The method according to claim 1, wherein the joint compound composition is in the form of a powder. 10. The method according to claim 1, wherein the joint compound composition is in the form of a powder comprised of particles having a diameter of at most 200 microns.
