HardieBacker Cement Board with HydroDefense Technology
Introducing from James Hardie, HardieBacker Cement Board with HydroDefense Technology — the first and only waterproof cement backer board. Installers can skip the step of waterproofing the entire board surface area and just waterproof the joints and fasteners; some application areas such as shower pans may require additional waterproofing, so refer to local building code requirements. Passing the ANSI A118.10 test for waterproofness, this innovation delivers a product that is easy to use and installed in less time.
