It is worst on one pier, where the surface of 1 or 2 of the bricks is starting to flake off in fairly large chips (two pics attached). I know I should get an appropriate builder or tradesman in to look at it, but I have a few questions, in case anyone could be kind enough to share their thoughts: 1. What would be the appropriate treatment(s) to fix the problem long term? 2. Two of the piers (including the one with the worst issue) were built from scratch 10 years ago, as part of a demolish/rebuild of the balcony. (It was a reputable builder, recommended by the Master Builders Assoc of SA.) These two piers had new concrete pads and were core-filled. Should there have been some treatment applied in the construction to prevent salt damp? 3. The pier with the worst issue also abuts a couple of feet of retaining wall at the bottom, on two of its four sides (pic attached). Might this be relevant? There are a couple of other small patches of the same issue on the main walls of the house, but nothing like to this extent (and the house is over 40 years old). Many thanks for any thoughts or advice.
