        "text": "Proper waterproofing requires a multi-layer barrier behind the visible tile surfaces. Installers start by ensuring the framing is sound, then install cementitious backer board or high-density foam panels. Next, a continuous waterproof membrane—either a sheet membrane or liquid-applied system—is applied over all walls, seams, screw penetrations, and inside corners. For the shower floor, a sloped pre-pan or mortar bed with an integrated drain flange is waterproofed and water-tested before setting any tile. Skipping these steps risks hidden water leaks inside the subfloor and walls.",
