A sheet membrane is a good choice for use as a water barrier in your built up shower pan.  Most sheet membranes are pliable, therefore, easy to roll out onto your shower floor.  Taking into consideration the size and shape of your shower floor, a sheet membrane can be installed as a single piece or pieced together from several pieces.  Where two pieces of a sheet membrane meet, they are overlapped a minimum of 2 inches, and further sealed at the seam with a manufacturer specific fiber mesh band. This ensures that your sheet membrane is a single unit and will maintain it’s waterproofing integrity.  Where joints and change of planes occur, extra care needs to be taken by applying the manufacturer specific mesh band or a fiber mesh tape along with a liquid membrane.  It is also important to remember that your sheet membrane installation will need to undergo a soak test where the shower pan is filled with water for a minimum of 24 hours to ensure that there is no leakage under or outside of the shower floor.
