Re: Pool Build - California Dreaming
Most pools do not have overflows; they are just a nice feature to have. Pool plumbers do not typically install them unless asked, as it is not the norm.
Quick question to clarify: The roof for the pool house is not attaching to the pool, is it? If I read your post correctly, it sounds like it is, and that is typically a big no no (unless engineered for it). You may have included this in an earlier post and I missed it, but I need to ask!
I haven't done a core sample in quite a while, so I can't help you there. 3,500 psi shotcrete down here regularly tests out in the high 4,000/low 5,000 range. If that holds for you you should have no problem meeting spec.
