Most people use about 25 gallons of water during a ten-minute shower. Over the course of a year that comes to 9,125 gallons of water per person. This would mean that a family of four uses 36,500 gallons of water per year, which is a tremendous amount of water and why it helps to have a moisture management service to help.
Waterproofing is the foundation of a successful bathroom. Many of the construction materials used in bathrooms such as wood framing, plywood, gypsum, wallboard, and more are moisture sensitive and need to be protected from vapor and water penetration. The key to preventing mold is moisture control.
Using typical backer board shower methods, a moisture barrier is installed behind the backer board and the backer board is installed on top of the moisture barrier. Tile and grout are then installed over the backer board. This layering method, while still used today, allows any moisture penetrating behind your tile and grout to saturate your backer board substrate. Water remaining in the backer board behind your tile will eventually lead to musty smells, mildew or even mold.
