So for that retaining wall that will house plantings … you absolutely need to make sure that the contractor applies a good cementitious water barrier BEFORE any tile or veneer or cap is placed on it. Concrete in not water proof and it acts like a sponge and a wick when it is in contact with ground water. Water will flow through the concrete and cause massive amounts of efflorescence on any surface material. It needs a water barrier. Both Laticrete (HydroBan) and UGL (DryLok) make decent products for that purpose. It get mixed on site and painted on to the wall (all sides and top) in 2 coats before any fascia is applied. Skipping that will result in efflorescence at some point right after you hand the pool builder your final check …
