Supplementary support of a 22-metre-deep excavation using anchors, nails, self-drilling reinforcement and steel members.
The Vanak office project required additional stabilisation of an excavation approximately 22 metres deep. Works included more than 2,100 m² of shotcrete facing and approximately 4,000 linear metres of drilling for anchors, nails and self-drilling reinforcement elements. Steel piles and walers were used in selected areas to reinforce the retaining system.
