ORANGE BASTION, GIBRALTAR
Stonehouse were asked (in tandem with John Newton) by the Government of Gibraltar to propose a solution to make four vast brick & stone interlinked tunnels water-tight so that they could be used as retail space. Named after King William of Orange, they had been used through many wars as storage for munitions on this strategically important territory.
We recommended a full cavity drain membrane system together with 8 sump chambers each containing 2 x NP750 pumps with battery back-up. We completed this large and complicated project on schedule, refreshing our operative teams every 2 weeks. Strategically, the first team drove to Gibraltar and then our admin team organised accommodation, flights and the delivery of materials throughout the phases of this sizeable and complex project.
