An impoundment is an engineering construction used for the safe deposition of unexploitable waste from industrial and mining facilities. In terms of the legislative requirements of the Slovak Republic, a “Measurements Project” must be developed for each impoundment.

The safety and stability of an impoundment are verified according to a ”Measurements Project” by considering stability at regular time intervals.
