A process for the production of membranes which contain at least one solid layer on one side of a porous substrate by treating, with a synthesis solution forming the solid layer, that side of the substrate which is to be coated is described, wherein, in the production of the solid layer on the porous substrate, the space which, viewed from the substrate, is behind that side of the porous substrate which is not to be coated is filled with an inert fluid, the pressure and/or the temperature of the fluid being chosen so that contact of the synthesis solution with that side of the porous substrate which is not to be coated is substantially prevented.
