Adjusting for foundation errors
Having once been a tiling contractor, I learned to work in a variety of contexts. Surprises were not uncommon. Sometimes those surprises were about the tile chosen by the customer’s ideas midstream in the project, and sometimes those surprises were about how well the house was prepared for tile before I got there. I remember one such situation where it was not until I encountered the corner of the huge bathroom that I realized there was something wrong. Tile doesn’t bend; it doesn’t stretch. So when I learned that the foundation forms had slipped four inches, and had not been repaired prior to the pour, I understood what I was up against. The room was not square. And I was setting marble – thankfully a random marble.
