RepairQ We are working on a renovation of an existing shopping plaza where some of the existing walls are split face block. Would it be an acceptable application to resurface the block with shotcrete to achieve a smooth finish? If so, what is the thinnest we would be able to go?
Shotcrete could be used for this application. The thickness of the overlay would be dependent on the material used. A potential concern would be the lines of the existing block showing on the new surface. We would suggest that you search for and review various ASA Shotcrete magazine articles as well as ACI 506R-05, “Guide to Shotcrete”
