I just think the reason for it not being available here is we dont have a market
persay and crude tar is used for foundations which could be because of our
lesser epa regs. I talked to a contractor that specializes in the water industry
and he never heard of such a thing. So I am lost on this one. I found the styro
though..I can get blocks up to 4' by 4' by 8'( that is in feet )

PS here in the us it can be mailed as long as it is labled properly.
