        "text": "Tile must not bridge an active expansion joint with rigid mortar because slabs shift with temperature changes and soil settlement. If a tile is mortared directly over a control or expansion joint, thermal movement will shear the bond and crack the tile line above it. Proper installation requires honoring the slab joints by placing an elastomeric sealant or a flexible expansion profile directly over the joint line in the tile layout. An experienced finish contractor will map these joints during dry layout to ensure the pattern looks balanced while allowing the floor to move naturally.",
