Liner failed on my 15x30 oval, all water emptied out. Liner is not in the budget until my wife gets off furlough and more income starts flowing back in. The pool otherwise is in really good condition. Is there anything I can do to brace the walls for the winter so I don't end up losing the whole thing? The liner split at the bottom along the edge so it will not hold any water whatsoever. I have some 2x4s and 4x4s, possible to use those on an angle to brace the walls?
