I have winterized ABG for years using ice guard inside skimmer w/o lowering water level. This year experienced severe winter and in early Mar noticed pool cover lowered. Obviously liner leaked causing weight of ice to transfer onto wall adjacent the skimmer. The wall buckled and has a split. Does not appear to have bucked the vertical braces. Have to wait until ice thaws to assess liner, in the mean time can the wall be repaired? Pool manufacturer stated this is not warranty, liner warranty is for workmanship defects. Assuming the liner can be patched and the buckling straightened out without removing too much water, I am interested in advice on structurally repairing the wall split/tear.
