Rob,
If encountering the breaking of forms (blow outs) from the vibrator then either the operator of the vibrator is not vibrating properly or your form builder is not building a proper concrete form. I have been working with concrete for over 35 years, including specialty concrete applications, the few forms I have seen blow out were due to improper form building techniques. The necessity in vibrating concrete and especially structural concrete is common amongst all concrete contractors. Regardless of it being a residential application or up to industrial applications, it is a necessary step in concrete work unless under special applications and specified specialty mixes. Vibrating is not just an air pocket issue about rebar and mesh, it is a permeability issue as well.
