That means the floor slabs upon which apartments sat were made of concrete that was poured around horizontal lengths of rebar, or stout steel rods, that provided critical strength when the concrete cured. To re-establish the integrity of the vertical support, it was initially decided to underpin the structure. The walkways were anchored by 1.5-inch steel rods, but the real issue lay in the change from a single set of hanger rods threaded through the upper walkways to a double-rod system that was anchored to the upper walkways themselves, adding immense and undue stress.
