The construction of the portal to the Šibeník tunnel has been completed.
The portal was formed from Maccaferri Green Terramesh system with a 70° face inclination. The project commenced at the east portal which is now complete. To meet the requirements of the National Road Authority, the face of the system is filled with stones instead of the more usual vegetative soil. The Green Terramesh is engineered from double twisted steel wire mesh type 8×10 with a Galmac + PVC protective coating. All temporary components within the structure are galvanized. Due to its height of up to 12m, the Green Terramesh face elements with 3.0m long reinforcement are enhanced with primary reinforcement formed by Paragrid polymeric geogrids – max. 11m long
