One of our assignments was to fill in all these existing vaults, which mostly contained old steam pipes. We rented an 80-foot boom lift from Drobach Rentals, and our crew uses it for all the facade restoration work. The process involves chipping away the loose concrete, installing rebar with epoxy, and then applying a SIKA product to fill in the gaps.
We removed all the windows you see over here on the left. These grids had glass between them, so we broke the glass and took out the steel grid. Then, we replaced them with block walls. Afterward, they created new window openings and installed the windows. All of these openings used to be windows, but we’ve blocked most of them up. Some now have new windows and fans.
This is our wire lath. We fasten it to the old brick and concrete walls using Hilti fasteners. Next, we apply a scratch coat of cement, and after that, the final coat. So, this is what it looks like before, and here’s the finished result.
