We had a sprinkler head fail, it shot a stream of water up to the soffit, which then found its way to the block wall, and it came out on the floor, damaging the carpet. The interior wall never showed any damage. So you might be seeing the same type of problem, the water gets in the soffit area, goes down the inside of the block wall and comes out at floor level.
NOTE: as referenced above there was a previous thread about a design flaw in Gardenias, I am very interested in this as we have a Gradenia. I contacted the original poster to get further info and never received a reply. I also contacted a home inspector to see if he knew of this problem, he did not. I will be VERY interested in what ever you find. If you do not want to post, please send me a PM.
Try contacting Frank DeAngelo, 352-250-7818, he can do an inspection, and give you an idea of what is going on. He has equipment to detect dampness in walls.
