The shower pan membrane liner is
The shower pan membrane liner is used to ensure a leak-proof shower.
Shower pan membrane liners are used to funnel any water that seeps through the floor or wall grout to the shower drain below. The shower pan membrane liner is made up of a flexible type of plastic material that sits below a bed of mortar, and the tile, in the shower floor area.
Prior to installing the shower pan membrane liner, the floor of the shower needs to be pre-sloped to ensure that the water will flow towards the shower drain assembly. The pre-slope is accomplished by applying a layer of mortar to the floor of the shower unit area. The layer of mortar is troweled in such as way as to create a gentle slope from the shower wall edges to the center of the shower where the drain resides.
Once the pre-slope mortar has cured, the flexible shower pan membrane liner can then be installed.
