HYDROINSULATION OF THE LJUBELJ TUNNEL

Synopsis
Ljubelj tunnel, situated on the international highway E 94, represents the shortest connection between Celovec and Ljubljana, i. e. between Austria and Yugoslavia. The total length of tunnel amounts 1369.7 m, while the Yugoslav part of the tunnel is 687.35 m long. The tunnel works began between the years 1943 and 1945. The work has been going on from the year 1959 till present. The observations in the last four years have shown that the whole concrete coating of the tunnel leaks water, especially when the rains are heavy. Author describes the procedure and results of
hydroinsulation works on the Yugoslav part of the tunnel that were carried out under the control of the Research Institute for Materials and Structures. This procedure required patented porous tiles and injection process. The repairing works on the Austrian part of the tunnel were carried out in different manner: the underground drainage system with the built in tubes made of synthetic materials was used there. The closing of accounts made evident the Yugoslav project to be less expensive than the Austrian one.
