HI: We have in-ground gunite pool about 15 yrs old. While the pool is just fine, the concrete deck around the pool has developed all around. Near the deep end of the pool the deck has settled almost 1.5-2". So there is a crack about 1" wide near the deep section. Elsewhere it is little more than a hairline crack.

The quetion I have is - what is the best fix for this? Can i simply get more concrete poured over it? I would like to conceal the crack and even the settled surface of the deck.

Any advice?

Thanks in advance.
