HI Abseiling Ltd were called to Watfords highest building, the 11 storey concrete building in the town centre. Built in the 1960’s the concrete was spalling and causing a danger to pedestrians. HI Abseiling were contracted to remove any loose material (concrete) from the building. We then conducted a full concrete inspection and survey. When the concrete samples were analysed in our lab, discussions with the structural engineers concluded that repair and monitoring would be the best way forward. The picture sequence below show the last stage of this process, the concrete repair. The lower right picture shows the finished repair.
