        "text": "Porcelain tile is completely waterproof on its own, but the grout joints and substrate underneath are vulnerable unless a certified waterproof system is used. For walk-in showers, tub surrounds, and wet rooms, installers mount cement backer boards or foam waterproof panels, tape all seams with alkali-resistant mesh, and apply a liquid waterproofing membrane or sheet membrane. The shower pan requires pre-sloping and liner testing before any tile is laid. This multi-layered barrier ensures water drains properly without penetrating framing, drywall, or subfloors.",
