Soil nailed wall – Séchilienne bypass
To increase safety on the RD 1091 road where it crosses through a very active landslide zone between Vizille and Séchilienne, NGE provided its expertise in the form of earthworks, strengthening works, blasting and civil engineering to create a soil nailed wall more than 47 metres high. The 18,000 m2 wall is reinforced with 100 AD/OC walling slabs (300 m2).
