Dowels @ SOG

Dowels @ SOG

Dowels @ SOG

(OP)
I was in a discussion with a friend earlier tonight and we disagreed over what is allowable with regard to dowels exposed in a section of SOG that will serve to connect to an additional port of SOG to be poured later - no set timeframe.

I say dowels are acceptble so long as they are not scaly with rust or lose cross sectional area. He says dowels must be installed via a HILTI epoxy.

This is a discussion about a residential outbuilding, and I have realized I am not very familiar with residential codes as he says they are very different than UBC codes.

Anyway, I am in Georgia, anyone want to shed any light?

Thanks,

Daniel

RE: Dowels @ SOG

I don't think I understand your question since I don't see how your two points are at odds with each other, they seem unrelated.  What exactly is the question?

RE: Dowels @ SOG

Either way will work.  You can put the dowels in place, leaving the future section exposed (but before you place the concrete in the future, cover the dowels with tape and grease them so that they slide (assuming you want your dowels for load transfer)), or you can drill holes into the formed surface and set dowels in epoxy.  That's more labor intensive though.  Plus, it you only want the dowels for vertical load transfer, no need to epoxy them after drilling.  Let them slip.

If you are tieing two slabs together for continuity, you may do it either way, it's just easier to set dowels while placing the concrete than to epoxy them later.

RE: Dowels @ SOG

Exposed dowel bars, given the open-ended timeframe for pouring the second slab, might be considered a safety hazard - particularly on a residential site.

I'd recommend drilling and placing the dowels at the time of the slab extension.
