The standard block or CMU wall connection is achieved with a 1/2" diameter hole through the Spancrete into the bond beam (filled top course) at 4' on center. A #4 (1/2" diameter) rebar is then driven into this hole, thereby providing a positive connection between the Spancrete and the wall. This economical connection is capable of resisting relatively light loads as shown in the Research note listed below.
