Ceramic Tile Expansion Joint Detail

Schluter systems prefabricated movement joint profiles protect tile edges and prevent sound bridges and surface water penetration resulting in a permanent maintenance free installation.

Ceramic tile expansion joint detail.

For ceramic glass and stone tile installation provides a very detailed explanation of the requirements and necessity for expansion joint construct design and placement. Every tile job needs expansion joints also known as movement joints they are critical to the success and longevity of the tile installation. If you tile over an expansion joint then you need to honor that joint in the tile as well. An expansion joint is in the substrate for instance in concrete.

Too many tile. It allows for movement in the tile. Recognizing that tile is a facade movement joints are needed to eliminate stresses that can occur between the substrate and the tile due to differing amounts of expansion and contraction. Here s where to put expansion joints.

The appropriate design of a movement joint is based on the tile or stone assembly s configuration and substrate type. Locate ctc joint in tile or stone surfaces directly above joints in sub floor full length may be fastened to sub floor using a construction adhesive trowel setting material making sure there is full coverage over the entire leg to ensure a smooth transition mortar bed may be feathered off both sides of joint. The tcna handbook recommends allowing for expansion and contraction in every tile installation. Tile expansion joints tile doctor ceramic porcelain and stone tile expands and contracts with thermal and moisture changes in the environment.

Learn all about expansion joints here. Consult tcna handbook for ceramic glass and stone tile installation detail ej171 for this vital information. Over any isolation or control joints in the concrete. An expansion joint is a strip of flexible material in this case caulk that lets tile expand and contract with changes in temperature.

The family of schluter dilex prefabricated movement profiles includes a variety of shapes sizes and materials to suit different applications. It s quite common to see controlled breaks in concrete and those are usually expansion joints. For installation of tile the tile ends at each control joint and the gap if filled with caulk rather than grout. Where should movement joints be placed.

The short answer is that you do not span control expansion joints with the tile. A movement joint is in the tile only.
