Why waterproofing matters
Tile and grout create the finished surface of a shower, but they aren't intended to be the primary waterproofing layer. Over time, moisture can migrate through grout joints, seams, and penetrations, making waterproof protection behind the tile an important part of a durable wet-area installation. A waterproofing strategy helps protect the wall assembly from moisture intrusion, reduce the potential for mold and mildew caused by trapped moisture, and support the long-term integrity of the installation. Hardie® Backer Pro makes it easier by providing built-in 100% waterproof technology that eliminates the need to apply a liquid waterproofing membrane over the board surface; helping simplify installation and save time on the job.
