This article presents a case study of a permanent avalanche protection embankment constructed at the Kaltenbachgraben avalanche path in the Gesäuse National Park, Austria. Given the strict environmental constraints and site‐specific boundary conditions, a vegetated geosynthetic‐reinforced soil structure was selected instead of a conventional massive stone‐faced embankment. The applied system consists of a prefabricated facing combined with polymeric coated steel woven wire mesh (PWM) reinforcement, allowing a steep dam geometry, rapid construction, and long‐term ecological integration. The geotechnical design was carried out in accordance with ONR 24806 and the EBGEO recommendations. Internal and global stability were verified using limit equilibrium analyses with the software GGU‐Stability, considering of load cases in accordance with ONR 24806, including horizontal avalanche loads. Construction was performed in a staged manner using locally sourced fill material. Construction‐accompanying static plate load tests were conducted to assess compaction quality and stiffness, revealing material‐dependent variability and underlining the importance of continuous geotechnical quality control. The results demonstrate that vegetated geosynthetic‐reinforced soil structures represent a technically reliable and environmentally compatible alternative for avalanche protection embankments in sensitive alpine regions.
