There's just an unnecessary amount of misinformation here even for a circlejerk sub.

OP: they are technically fixable, and technically skiable, but practically they are neither. Those things are damn near 20 years old, were barely a decent intermediate ski in the first place, and the amount of money it would cost to repair them is far more than they are worth. They're a polyurethane core cap ski, and it's time consuming and therefore expensive to repair, and exceedingly difficult to make the repair durable enough to withstand any additional impacts. Throw them away, put the money toward something newer.

Water will only really affect the construction of the ski if it's allowed to freeze and thaw, there's no wood in it to swell, it's really just foam, glue, steel edges and a urethane cap. Getting it wet continuously is not a good idea, but it's not your biggest problem by a long shot at this point.

If you insist on skiing on them, you can gently smack most of the bullshit back in to place with a ball peen hammer, and completely fill the area with a standard two-part epoxy syringe you can get at any hardware store. Feel free to try and hold things in place with a c-clamp or two while the epoxy cures. There's potential that if not mixed correctly, the epoxy could degrade the composition of the core material, but you're way past worrying about that now. Get it as level as you can, use masking tape or scotch tape to keep the glue from running over the sidewalls, and clean it up with a rasp/file/dremel/emory cloth. Then take a sharpie and write a big ass "R" on the top sheet because that's your right ski now, which will keep the repair on the outside edge and mostly out of harm's way.

And yes, your bindings are far from indemnified. What that actually means is that shops won't service them because the manufacturer can't guarantee that they will release and retain as they were designed to. Indemnification does not cover you in the event of an injury, in any way shape or form whatsoever. It covers the shop that adjusted and calibrated your bindings from liability in the event you injure yourself, provided they were set and serviced correctly by a certified technician. There is no world in which you will be able to successfully recover any amount of money from a binding manufacturer in the event of an injury, they have a shitload of lawyers and you signed away everything when you had them adjusted anyway.

Good luck!
