Linear Drain Guide
Waterproofing
Common methods using a clamp down floor drain:
PVC Membrane/Vinyl Liner (Polyvinyl Chloride): A plastic sheet
available at most plumbing suppliers and sold in rolls of 4’, 5’ and 6’. The
membrane is layered between mortar beds and the corners are folded
to create the shower pan liner. If the shower pan area is larger than the
roll dimension, it must be seamed or joined together. Tile cannot bond
directly to this type of waterproofing.
Lead Pan/Copper Pan: A metal sheet that is formed to create the shower
pan area. The membrane is layered between mortar beds and the corners
are folded to create the shower pan liner. If the shower pan area is larger
than the sheet dimension, the lead material must be welded together. This
install is more common in metropolitan areas where code may require a
metal pan. Tile cannot bond directly waterproofing.
CPE Membrane (Chlorinated Polyethylene): A rubber sheet available
at most plumbing suppliers and sold in rolls 4’, 5’ and 6’. The membrane
is layered between mortar beds and corners are folded to create the
shower pan liner. If the shower pan area is larger than the roll dimension,
it must be seamed or joined together. Tile cannot bond directly to
waterproofing. CPE Membrane is also branded as Chloraloy™ by Noble.
Hot Mop (Tar): Heated liquid tar is applied or ”mopped” on the
shower area to create the shower pan and is similar to waterproofing a
roof with tar. This installation is most common in California. Similar to
fiberglass waterproofing.
Methods using a bonded flange:
Liquid: Roll or paint-on liquid membrane that can be applied on
floors, walls, and ceilings and bonds directly to the drain flange. The
total install time is shorter than traditional waterproofing methods
and typically saves 2 to 3 days. Infinity Drain recommends and offers
Hydroban
TM waterproofing by Laticrete TM . Hydroban TM is a self-curing
product that is ready for flood testing in 2 to 5 hours. Tile can bond
directly to waterproofing.
Fabric Sheet: Sheet membrane that bonds directly to the drain flange
with an adhesive and is sold in most tile suppliers. Corners (in and out)
are available to avoid folding. If the shower pan area is larger than the
roll dimensions, it must be seamed or joined together. Tile can bond
directly to waterproofing.
