CHICAGO, IL – Tension Testing was done on Friday, August 4th to test the strength of the stainless steel rods in the new brick and bond beam construction. 5-7 layers of existing brick were removed to install new brick with a bond beam on top. 24” stainless steel threaded rods in a mesh sleeve are installed every 8” alternating 16” o.c. (on center). These rods tie in the existing brick to the new construction creating a stout bond and strengthening the top of the wall. This is all preparation work for the new steel trusses.
