12 PROGRESS PROFILES - PRODESO HEAT SYSTEM
Waterproong - Movement/Expansion joints
Waterproong
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 oor 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 nd themselves facing new challenge every day. Water
penetration can cause extensive damages to the tile assembly itself as well the suboor and the
oors underneath the tile assemblies. Waterproong 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 ooding. Waterproong 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 waterproong foil tape (doublesided Polypropylene foil tape) and modied (ANSI A118.11) or unmodied (ANSI
118.1) thin sets.
Movement/Expansion joints
Any tile surface assembly cross section is made of several dierent materials, Tiles, Wood, Screw,
Cement, Gypsum, Adhesives, Beams and more. All these dierent materials contract and expand
in dierent 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.
