Yes J_Palmer_Cass suggests using 3/4" pressure treated ply, with stainless screws, and lining the inside with pool foam before installing the new liner. If you can find a marine-grade P/T with an A/C side, rather than C/C, that would be better. The wood waterwalls run about $120-130/ sheet but 3/4 P/T ranges from $35-55/ sheet and pool foam is about $50 for a 100' roll, 48" wide. The math is compelling.
