Discoloration of concrete pool decks can be due to a number of causes including weathering, sun exposure, improper color application, and attack by pool chemicals. The good news is that in most cases the concrete color can be revived by applying a new coat of acid or water-based stain.
The foam runs the entire perimeter of the pool between the coping and the deck, "approx. 115 linear feet" chemical seller's estimate . The gap is about 1/2" and the foam is about 3/8". I know when the deck was put in that the foam is about 4-6" high whatever thickness the deck is .
I moved into a house where the pool deck was cracked and sinking about and inch now since I moved in. I just discovered that the pool drains on either side of the deck were clogged and the water was running back under the deck and then out, leaving several inches of air space between the deck and the soil.
