        "text": "Waterproofing behind shower and tub tiles is absolutely essential because grout and tile alone are not waterproof. Water naturally seeps through grout lines and hairline cracks over time. Without an underlying waterproof barrier, moisture penetrates the backer board, framing studs, and subfloor, leading to mold growth, rot, and structural decay. Professional installations require cement backer board or high-density foam boards coated with a liquid-applied waterproofing membrane or a bonded sheet membrane. Proper installation also includes integrated corner seals and waterproofing around pipe penetrations before any thin-set mortar or tile is applied.",
