Precast Panel Repair With Sika Products
Concrete repairs to the precast “eyebrows” on this building involved the following steps. First the loose concrete was removed, then the rust was completely removed from the reinforcing steel. Sika Armatec® 110 EpoCem® rust inhibitor / bonding agent was then applied to the steel and the concrete surface. Next, one “lift” of Sika Corporation, SikaTop®-123 Plus mortar was applied. The maximum amount of that material that can be applied in each lift is 1 1/2”. The depth of most of the damaged areas was less than an inch-and-a-half so in those spots only one lift was needed. Others were deeper so those spots required additional repair if the building was to be restored to its original form.
