The standard NDT & Core tests were conducted and were concluded that the columns have not achieved the required grade of concrete. The various option of retrofitting was considered like Jacketing, Steel plate bonding and epoxy Injection. Sika India`s technical got involved in the project along with applicators and provided the unique solution using state of art technology of externally bonded fiber reinforcement (SikaWrap & Sika Carbodur System).
