        "text": "Yes, porcelain tile requires a completely flat, rigid, and stable subfloor to prevent cracking and broken grout lines. Porcelain has virtually zero flexibility, so excessive deflection or uneven spots in plywood subflooring will cause tiles to loosen or fracture under weight. Before setting tile, contractors inspect the subfloor, reinforce joists or plywood if necessary, and install a cement backer board or an uncoupling membrane. Addressing subfloor unevenness during prep ensures proper mortar coverage beneath each tile, eliminating hollow spots that compromise durability.",
