Renovation contractors working with homeowners on kitchen or bathroom projects frequently hear concerns about the potential for water damage. Requests for waterproof shower enclosures have become common, even when the building code doesn’t require waterproof shower enclosures. PermaBASE Building Products, LLC, an affiliate of National Gypsum Company, expanded its product line with PermaBASE WP® Waterproof Cement Boards to provide homeowners and contractors peace of mind and to simplify waterproof installations.

In this episode, Chris Whitmire, director of product marketing for National Gypsum, talks to Eddie Neel, market manager for PermaBASE, and Tony Fuller, director of technical and product development for PermaBASE, about the benefits of using PermaBASE WP.


Listeners will learn:

  • About the PermaBASE® Cement Board product family and how PermaBASE WP is different from other PermaBASE Cement Board products.
  • Why waterproofing is a preference, not a code requirement.
  • How PermaBASE WP helps installers save on installation time and materials.
  • How PermaBASE WP is constructed and tested for waterproofness and mold resistance.
