Exterior concrete restoration and repair of “ Bloomfield “ Stadium in Tel-Aviv
Project Description
A unique project involving the rehabilitation of extensive areas in short periods of time
As part of the stadium expansion project, we were requested in 2018 to rehabilitate the perimeter stands, which include the stadium column and support beams. The concrete elements are characterized by thin concrete cover of the rebars and the extensive corrosion damage is evident throughout the stadium. The works were performed between the stage of extension and construction of the new concrete frame and the stage of system installation.
Prior to the commencement of works, various technologies were experimented with for the swift removal of the loose concrete.
