Not to get too far off topic here, but how do you bond an existing vessel that is to be converted to a swimming pool?
I am working with a church camp which was given some rural land. We have a large livestock tank built, as far as anyone knows, in the 1930s. It is filled by overflow from the drinking water tank, which is filled by an old Aeromotor windmill. Naturally enough, it gets used for swimming. We have a PT deck & stairs, floatation devices and the like. Now we have folks talking about adding a filter pump and making it into a real pool. It is of limestone construction.
Are we required to "bond" this, and if so, how? Do we have to add rebar and pour more concrete?
