By a method for cancelling of condamned subterranean tanks by filling is used compressed air to convey the filling material (14) through a hose (1) from a pressure vessel (16) placed in substantial distance from the subterranean tank (2) and to inject the filling material into the subterranean tank (2) for the filling thereof. The cancelling of subterranean tanks thus obtained is simple, cheap, and careful with respect to the surroundings, as the work may be performed without noticeably intervention in surrounding areas such as gardens, terraces etc. |
