ABSTRACT OF THE DISCLOSURE A sealing screen for waste dumps, e.g., for garbage dumps and the like, consisting of protective impermeable layers. The layers include two sealing layers and a control filter layer that is interposed between sealing layers. Two piping systems, an injection line and a second line system, are arranged within the control filter layer. The sealing screen has individual areas which are partitioned off from each other by means of sealing connections between and perpendicular to the sealing layers. A collector shaft or a tunnel are provided for checking the seal integrity in each individual area. A drainage layer with a drainage line system is arranged above the top protective layer, and a sealing layer is provided for protection above the drainage layer against damage from the dumping of waste into the dump. In the event that the seal fails in a particular area, the control filter layer is filled with a hardening and sealing material via the pipes of the injection line for that area, with the result that the integrity of the seal is reestablished.
