My PB tells me there is no such thing as cold joints with Gunite. I did some research and found that to be true if first pour was less than 7 days old, proper cleaning, etc. Well my shell is almost 1 month old. There was some miscommunication between PB and gunite sub. They poured my tanning shelf 6 Inch too short In length. I was ok with it, but sub proceeded to chip out the edge to extend it (using shotcrete). initially he was going to just shoot extra gunite. I told him that he needed rebar, so it would not crack. He reluctantly agreed…drilled some holes and added some rebar. I told him that he either needs to epoxy rebar into existing or uncover rebar and tie into it. PB disagrees and says don’t need that.
I can’t imagine that just shooting additional gunite without rebar is acceptable (and since rebar dowels are just drilled, I am assuming they will not provide any benefit) and will eventually crack in the plaster….even just cosmetic. I don’t want to see / deal with that after paying $100k for a new pool. Should I worry?
