DUMP FORMATION AND METHOD OF MONITORING AND REPAIRING LEAKAGES IN DUMPS

There is involved a method for monitoring and possibly repair leakages in dumps with at least one lower seal inclined toward a control gallery, the lower seal being divided into leakage troughs and the leakage troughs being connected to control openings leading into the control galleries. If seepage water emerges from at least one control opening, an inspection pipe integrated in profiles or webs of a profile foil forming the leakage troughs is probed to locate the leak. Below the lower seal a control pipe is driven into the localized leakage area, so that also the tightness of the lower seal can be examined, and, depending on the testing of the seepage water, repair of the upper seal is either carried out immediately or is postponed. Immediate repair is necessary if the leak is already in the lower seal.
