Replacing concrete deck

[maherba]

Okay, thanks, PoolDoc. Here's a bit information: I'm just north of Toronto, Canada, so a cold zone. The deck heaved over the winter a couple of years ago -- we think it was because of an undetected hole in the liner that led to water getting into the ground. The steps cracked, too, and were repaired last year. The deck has cracked in several places and pieces of the concrete have popped out. I'm attaching a photo of one of the cracks that I took last spring.
