Thanks for the info gentlemen.
Stewart, yes, it seems only England uses the form in the link supplied. I see that as strange since it looks to be an excellent solution to the problem; connecting new to old.
BridgeMan, do you have knowledge of a location or link to pick up standard brink ties? I'm not having any luck finding any locally; home depot, lowes, dixieline, or ace hardware. Seems I'm not very good at Googling for them either...and at this point only require maybe 20 ties at the most.
Another question; what about tying the walls together by extending bond beam rebar through to existing wall, affixing with cement? Would there be an issue with expansion due to differences in the walls?
