One of the most devastating things that can happen to your home is water damage. There are many techniques used today to waterproof a walk in shower but we have found that the only reliable method is one that employs the age-old art of the hand floated shower.
By floating the pan of the shower floor in a two-step process, it allows for the layering of your waterproofing system with the integration of a two-part drain so that no water can ever be trapped without a place to properly drain.
We use a continuous rubber membrane that extends up the bottom part of the wall approximately eight inches or higher. Then half inch green board dry wall is applied to the wall from that point to the ceiling. This is then all covered with builderís felt, which extends beyond the drywall from floor to ceiling. Metal lath covers the shower walls with special care not to penetrate the rubber membrane at any point. A special mix of concrete formulated for floating showers is then applied by hand over the entire shower in preparation for the tile application. It is the time consuming, skill-requiring method of applying all of these layers that insures a waterproof walk in shower. The added benefits to a hand floated shower is that it creates a monolithic unit that is plumb, true and square and one that resists cracking in the corners and at the junction of the floor and walls. These methods create a surface that is the building block for the perfect tile layout.
Often when replacing a dated shower from the 1940ís or 1950ís, we will find the wood in the walls and the floors to be perfectly dry and uncompromised. We rely on these time-proven methods. We canít tell you how many walk in showers we have removed because of the defects of modern techniques, materials and workmanship. It is a false economy to skimp on waterproofing and donít let anyone tell you otherwise.
