Waterproofing - Movement/Expansion joints
Tile surfaces (Ceramic and Natural Stone) are preferred and chosen because of
their Beauty, Color, Design, Finish, and Texture. Tile surfaces are used for both
floor and walls in a variety of project from residential, commercial, hospitality,
institutional, health care and industrial. The use of tile has become so extensive that
tile installers find themselves facing new challenge every day. Water penetration
can cause extensive damages to the tile assembly itself as well the subfloor and
the floors underneath the tile assemblies. Waterproofing is required under and
around tubs and showers. It’s also recommended to waterproof tile assemblies that
can possibly be exposed to considerable amount of water because of flooding.
Waterproofing the tile assembly is cheaper and safer than repairing water damages.
PRODESO HEAT MEMBRANE, is a Polypropylene membrane and as such
is naturally waterproof. For indoor installations in areas that are prone to water
damage, the corners and seams of the PRODESO HEAT MEMBRANE need to
be waterproofed utilizing PROBAND 150/250 waterproofing foil tape (double-
sided Polypropylene foil tape) and Unmodified Thin-Set ANSI A118.1.
Any tile surface assembly cross section is made of several different materials, Tiles,
Wood, Screw, Cement, Anhydrite, Adhesives, Beams and more. All these different
materials contract and expand in different ways when temperature, moisture and load
change, causing stress in the overall tile assembly and ultimately cracks and possibly
delamination of the tiles. Ceramic and Natural Stone Tiles are rigid and are not
capable to compensate for movements. An expansion/movement joint is the part of
the assembly designed to absorb the stress on the assembly by allowing movement.
PRODESO HEAT MEMBRANE does NOT eliminate the need for expansion/
movement joints, including perimeter joints, within the tiled surface. Movement joints
must be installed in accordance with industry standards and norms TCNA EJ171, and
TTMAC 301 MJ.
Expansion/Movement Joint Placement
• Perimeter Joint need to be installed around the entire installation perimeter.
• Surface Joint: 16’-20’ (4.9meters - 6.1meter) in both direction.
Reduce separation by 25% if exposed to direct sunlight, heating cable or moisture.
• Surface Joint near any structural element (columns, beams, stairways), doorways.
• Structural Joint when 2 separate supporting structure meet under the tile
or the underlayment.
• Areas enclosed within joint should be a rectangle with ratio between each dimension
not to exceed 1: 1.5.
