Western Wall Tunnels: Reinforcement of the Wilson's Arch excavations

  • Client: The Western Wall Heritage Foundation

  • In order to enable archeological excavations adjacent to the Western Wall, it was necessary to construct permanent ground anchors to strengthen a wall from a later period which was discovered at the edge of the dig. Due to the high sensitivity of the site, and the need to prevent any contact or dripping of grout onto the antiquities, a special geotechnical filter sock was used. This prevents any leakage of grout out of the drilled space, but enables full contact and maximal friction with the ground. The anchors were constructed to a drilling depth of 12m to withstand a 30-ton force.
