Foundation - Can't it crack if a tree hits the top of your house?

Quick background - a tornado went through my neighborhood and the two taller than heck trees that were in my back yard ended up on my house.

So the house has been 'mostly' fixed. The money has been spent - none of it was for a cracked foundation. I'm not sure if they even checked that.

PROBLEM: water keeps seeping up through the floor in the kitchen. I know it is coming up through the floor because sometimes you can't even see any until you step on the floor - then you can see little beads of water squeeze through the seams.

This never happened before the tornado.

So I've done a ton of detective work. I have found that it is the a/c line - the condensed water pvc pipe runs under the kitchen. Somehow the pvc got broken and the foundation was cracked.

I know for a fact it is the pvc condenser pipe because I unhooked it from the pipe and have it draining into a bucket that I change twice a day. Now there is no water in the kitchen. I've ran the dishwasher - its rained really hard outside - still dry.

How do I prove it was from the tornado? Who do I call? (please don't suggest my contractor - I literally never want to see him again.)
