A decoupling membrane like Ditra should be used in almost every situation.

I'd disagree that cracks in basement floors happen in every home in New England. I've been in plenty with no cracks. It's more accurate to say that they aren't that big a deal.

If you want to fill it yourself, I'd recommend Sikaflex 1a.
