There have been many stories on Pond Boss about good dirt contractors with good work ethics that still can't build a pond that doesn't leak.
I have no idea how much of that applies to your contractor! However, it would be nice to learn if he had built other ponds in the area, with similar soil conditions, in February, that did not leak.
My father has an excellent cardiologist because he has lots of heart problems. However, he turned to a different doctor for his knee replacement! I think our best advice is that you need to make sure your "pond guy" is an actual "pond guy".
