Bentonite is an ore whose dominant constituents are the clay minerals of the smectite group, and within which montmorillonite is the most represented.Montmorillonite has a pronounced swelling ability and low hydraulic permeability.Due to its hydraulic characteristics, that is, its extremely low water permeability, bentonite is often used today as a new material in engineering waterproof barriers.
Frequent occurrences of instability of the slopes have been observed during the general condition assessment of the embankment in the „Gornja Sava“ floodplain. These phenomena directly affect the stability and thus the functionality of the embankment.Following the critical damage of the „Sava“ embankment in the village of Mlinarice, from March 2018, it is acceptable to consider ways of applying new materials (bentonite and geotextile with bentonite) in order to ensure the safety and functionality of the embankment.These materials are particularly applicable in emergency interventions on embankments during flood waves.

Ključne reči: bentonite; geotextile with bentonite; embankments; water- protectiv facility; emergency interventions; functionality.
