Pool arriving tomorrow. Installing in a slope with one side inground. We're wanting to have a concrete patio poured flush with top edge of the pool on the side that's inground. The pool uses a beaded liner, so I guess we won't have to remove the top rail to install a new one. Do you think it's feasible to concrete against the top rail? What's the possibility we'd ever need to remove the top rail? Thanks for the help.
