Summary The Keban Dam was completed in 1974 on the Euphrates River in the eastern part of Turkey. The main dam of rock fill and concrete gravity structures rests on a karstic marble and limestone. The so-called ”Crab Cavity”, which was found during the construction in 1971, is the largest cavity encountered in the foundation of Keban Dam, on the left abutment and about 320 metres below the crest level. The volume of the cavity was estimated to be about 104 000 cubic metres. The cavity was plugged by using approximately 63 400 cubic metres of tremie concrete, slurry and neat grout, which plugged the downstream half part of it.
