Ceramic Tile Expansion Joint Detail

It is important to note this detail for both ceramic tile and stone applications recommends a movement joint be placed at one or both ends of the tile bridging the underlying crack as recommended by the membrane manufacturer.

Ceramic tile expansion joint detail.

Height to match tile stone or wood thickness. 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. A movement joint is in the tile only.

Latham standard loc strip hard flooring expansion joints are capable of absorbing extension and compression equivalent to 16 or 20 of the undeformed width of their elastic neoprene cores. Thus 12mm joints can be compressed to about 10mm and extended to about 14mm 6mm compressed to about 4 75mm and extended to about 7 25mm. Where should movement joints be placed. It allows for movement in the tile.

To help protect your tile from future damage you ll need to include expansion joints into your installation. Movement joints are an integral part of any tile assembly and must be incorporated within the tile field at doorsills and at transitions to walls and other restraining structures to allow movement of the assembly and prevent stresses that can damage the system. An expansion joint is in the substrate for instance in concrete. It is best to achieve a two sided bond only to the flanks of the open joint in the tile.

Possibly the best type of expansion joint material that can be used is a flexible silicone e g. 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. An expansion joint is a strip of flexible material in this case caulk that lets tile expand and contract with changes in temperature. The tcna handbook recommends allowing for expansion and contraction in every tile installation.

Over any isolation or control joints in the concrete. Manufacturer ceramic tool company. It s quite common to see controlled breaks in concrete and those are usually expansion joints. If you tile over an expansion joint then you need to honor that joint in the tile as well.

Anywhere tile meets a vertical surface like steps or the foundation of your house. Tcna s handbook mandates a soft movement joint every 20 25 feet 6 7 6 m for interior installations closer if exposed to sunlight and moisture and every 8 12 feet ba 2 4 3 6 m for exterior exposure installations ej171 09. Schluter systems prefabricated movement joint profiles protect tile edges and prevent sound bridges and surface water penetration resulting in a permanent maintenance free installation. Latasil or urethane sealant placed over a closed cell foam backer rod.
