Yes! Is a movement joint the same as an expansion joint? No Is it the same as a control joint? No What are movement joints? Also known as soft joints. Simply put- a movement joint is a gap, or space, next to a tile that lets a tile floor move a bit. There are two kinds of movement joints: perimeter and field.
Why do we need movement joints in floor tiles?
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. Where should movement joints be placed? The TCNA Handbook recommends allowing for expansion and contraction in every tile installation.

When Should expansion joints be used in tiling?
We recommend using expansion joints at intervals of at least 6m for heated floors, and 8m for unheated floors. Therefore if your room measures only 3m wide but is over 8m long, you will need to add an expansion joint.
How often should I tile expansion joints?
Joints must also be formed within the tile field, every 12 to 16 feet in each direction for exterior floors and for interior floors exposed to sunlight. These are to be kept clean of mortar and grout when the tiles are set, and not created by saw-cutting after the floor is in place.

Is expansion joint necessary?
Expansion joint failure can happen for several reasons, but regardless concrete needs a buffer as it goes through the natural cycles of expansion and contraction. So, this has always been the case, and this is why expansion joints are necessary.
Can you lay tile over expansion joint?
1.1 states, “Openings for movement joints shall extend completely and directly through tilework down to structural backing.” This sentence means that when tile is installed on a concrete floor which contains expansion joints, a sealant joint (aka caulking joint) must be placed in the tile installation immediately above ...
Does porcelain tile need expansion joints?
"One of the most basic and important facts an installer should know when working with ceramic (including porcelain, glass, and natural stone) tile is to always have expansion joints in place. If expansion joints are not part of the installation, failure is lurking in the shadows waiting to strike.
How much space should be between tile and wall?
The Tile Council of North America recommends at least a quarter-inch gap between the tile floor and the walls. Never fill this gap with grout, because tile grout is not flexible. Instead, fill it with an elastic material capable of sustaining the movement of the floor and the movement of the wall.
What is the maximum spacing of expansion joint?
Expansion joint Maximum spacing of expansion joints range from 25-27 m in jointed reinforced concrete slabs, and from 40 m (for slabs <230 mm thick) to 60 m (for slabs >230 mm thick) in unreinforced concrete.

Why Do You Need Expansion Joints When Installing Tile?
If you're wondering why you need to include expansion joints when installing tile, you've come to the right place. Let me explain why they are so important.
What is expansion joint?
Expansion joints are also known as Movement Joints or Movement Accommodation Joints. In ceramic, porcelain, glass, and stone tile installations, they are critical to the success and longevity of the installation.
What is the minimum size of perimeter joints?
For interior perimeter movement joints at perimeter walls-not less than 1/4” (6.35 mm) which is commonly covered by tile trim, cove base, or shoe molding. Perimeter joints, other than perimeter walls-preferred not less than 1/4” (6.35 mm), but never less than 1/8” (3.18 mm).
How big should grout joints be for tile?
For tiles subject to direct sunlight or moisture: quarry tile – same as grout joint, but not less than 1/4” (6.35 mm); all other tile – preferred 1/4” (6.35 mm), but not less than 1/8” (3.18 mm).
Can a certified tile installer install movement accommodation joints?

How much does a grout joint need to be to change plane?
For a change of plane (floor to wall or wall to wall) – same as grout joint, but never less than 1/8” (3.18 mm).
Does elastomeric sealant bond to tile?
Notice that the elastomeric sealant is attached only on the sides of the two adjacent tiles. One critical point here is that the sealant does not contact or bond to the sides and/or bottom of the joint. If the sealant is allowed to do so, it is locked in place and will have zero movement ability.
Why do we need movement joints on 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.
Why is tile heaving off the floor?
Tile heaved off the floor, or tented, and sometimes cracked is often a sign that movement joints were not used sufficiently. For tile over concrete, the curing of the concrete places the tile under compression.
How long does it take for tile to tent?
How long it takes tile to tent is directly a function of at least three variables - the rate of concrete shrinkage, the shear strength of the thinset, and any expansive forces applied to the tile layer (for example, heat). When the tile is poorly bonded, the tile can tent very quickly. If there is a strong bond, often the grout will compress significantly before the tile will lose its bond. Of course, the type of tile is important as well. Thinset has a harder time bonding to porcelain than most other tile. At the other extreme, I have seen a saltillo installation where the tile did not tent but rather spalled as the thinset and grout were stronger than the tile.
What happens if tile fails with a loud report?
When tile fails with a loud report, this certainly indicates that a good bond was present. Only when the shear force exceeds the strength of the bond, will the tile let go. Frequently, either the tile or the concrete will be without thinset residue - as if the thinset was not applied correctly originally. Usually, if the tile is tenting years after the installation, this was not the case. Had the thinset not been applied correctly originally, the tile would have tented long before. Rather, it is important to consider that the cleavage plane will usually occur at the thinset transition - either the bond to the concrete or the bond to the tile, depending on the relative permeability and exact composition of each.
Do tile installations need to be moved?
In summary, every installation should allow for movement. Properly designed installations, where expansion and contraction do not create shear forces, should have no problem for the tile to stay well adhered.
Do movement joints need to be placed frequently?
We cannot specify the exact location nor frequency of movement joints as there are many site related conditions that must be addressed; however, we do offer guidelines in Detail EJ171 in the TCNA Handbook. It is especially important to note for interior installations, movement joints are placed more frequently when moisture or direct sunlight is expected. For exterior installations, the range of temperature from summer highs to winter lows must be considered.
Do movement joints need to be used more often?
If the areas exposed to sunlight are warmer than surrounding areas, movement joints should be used more frequently. If the tile surface is not appreciably affected, no accommodation is needed in the joint spacing. Only the area subjected to increased temperature needs to have movement joints more closely placed, ...
What is expansion joint?
Expansion joints are spaces between tiles that, instead of being filled with grout, are filled with a flexible sealant. The type of sealant (also called the "caulk" or "caulking") chosen must be weather-resistant. Moreover, if you expect to be subjecting your patio to a lot of traffic, you must select a sealant designed to hold up to foot traffic.
Why does tile move?
The elements can take their toll on pieces of tile used outdoors. These elements include direct sunlight, freezing temperatures, and snow and rain. All of these conditions can cause outdoor tile to move, and you need to allow room for it to do so. If the outdoor tile does not have room to move, it will make room. Grout will crack.
Why is my patio tile ruined?
Entire installations can be ruined because of a lack of expansion joints. Outdoor tile expansion joints are a small but necessary step when building an outdoor tile patio that you expect to last for many years.
Do outdoor tiles move?
After installation, outdoor tiles move. It sounds like a strange concept that a solid material, installed with a cement product, is going to move. Well, it may sound strange, but it is also true. Outdoor tile and the materials used to install it expand and contract, just like wood and other building materials.
Do you need expansion joints for patio tile?
If there are joints in the concrete slab under the tile, there needs to be an expansion joint in the concrete slab, as well. Otherwise, the movement that those joints allow in the slab could carry up into the tile and compromise your installation. Make a note of where your outdoor tile expansion joints will go when doing the patio layout .

What should be the gap between tile and wall?
These are the kind that every tile installation should have. When you place a tile next to a wall it should have a gap between it and the wall. That’s a perimeter joint. There should be a gap around the entire floor (or wall). Typically this gap doesn’t get filled with anything. Typically it’s covered by baseboards around the room.
