This is new construction, slab-on-grade home that was completed about 3 months ago. The parging on the garage walls has discolored spots which look damp, especially at the bottom and between the cinder blocks. Concerned there might be a moisture issue, or possibly the foundation was not built properly (done in extra wet conditions or maybe the mix was wrong?). Thought maybe it was a leak in the plumbing (which was routed through the slab) but checked the water meter and it doesn't move when all fixtures are off.
Is this something I should be concerned about?
