In response to the large number of tunnels being dug, which could be used for infiltration by militants, in mid-2017, Israel began construction of an underground border wall several meters in depth along the entire 60-km length of the border. The wall is equipped with sensors that can detect tunnel construction. The wall is located entirely on Israeli land.

Moseroth installed the “Upper Fence” above the anti-tunnel underground wall in 2019-2021. The fence height is 6 meters and it demanded approx. 15,000 tons of steel and metal.
