Pre-drill holes and epoxy 80 #5 rebars into concrete footing.
I need to find the required depth of pre-drilled vertical holes to epoxy 80 #5 rebars into the top a of an existing concrete footing. There will be a new concrete overlay on top of the existing footing. I need composite action in flexure of the new overlay with the existing spread footing. Shear friction between the two concrete layers will be resisted by the #5 rebars. With so many rebars, I need to know the minimum depth required to drill the holes to.
