Comment: The concrete deck around the one end of the pool is settling and cracking pretty bad. I am in need of removing the current concrete and installing new decking. May also design information as we would like to expand the decking around the pool. To expand the decking we will probably need some type of retaining wall built as well. Depending on the area of deck expansion the retaining wall may be just a foot or two high or could be 5-6 foot high.
