Within the construction group of products based on bentonite, the product BENTOPROSEAL-A is successfully being used in the project of injection of Buško Lake near Livno (Bosnia and Herzegovina). The project started at the end of 2019. This year contractor is planning to build a large grout curtain using bentonite-based injection masses.

Buško Lake, as one of the largest artificial accumulation lakes in Europe, is located on a predominantly karst terrain with a large number of abysses, due to which it has extremely large water losses. The works continued in June 2020, and due to the size and complexity of the project, it is planned that the implementation will last at least two years from the start of work. The main contractor on this project is Geosonda d.o.o. Zenica.
