Tile Installation Expansion Joints Are Critical

SUBSCRIBE Learn how to tile the right way
Every tile job needs expansion joints, also known as movement joints, they are critical to the success and longevity of the tile installation. Too many tile installations are done without consideration to how tile will expand and contract with the change of temperature and humidity, and not only the tile surface, but the building itself. If there is no room for movement where tile meets a wall or some other hard object that will not move, then when movement does occur, and it will, something has to give, and it will usually be the tile installation. Tenting or popping of tiles is the end result when the tile floor needs to grow, but has no room for that to happen.

Sal is the Godfather of tile... when he speaks everyone should listen and take notes!

@460sw3 6 лет назад

Another great lesson Sal! I really wish more "tile guys" would follow this rule.... it would save the customer from a big headache later.

@SalDiBlasi 6 лет назад

Probably the most ignored component of a tile installation, and one of the most important.

@SalDiBlasi 6 лет назад

akakiashi That is more common than you might think, they think that tike does no expand, no matter how small movement might be, it adds up to quite a bit over long runs of tile, enough to cause it to fail.

@SalDiBlasi 6 лет назад

Go on youtube, do a search for "tenting tile" see what can happens when you ignore movement joints.

@bertkutoob 5 лет назад

It took 15 years... Spent the weekend lifting & replacing 4m². Contractor long flown the coop so DIY. Fortunately had lots of spares from the original job so no problem matching... Grouting tomorrow, but oh my aching back!

@Happynsnappy 5 лет назад

Thank you for the great information. Cracking in one spot happened after 17 years in my tiled kitchen, then 10 days later 18 tiles tented. The cracking sounds were so loud and pretty frightening at the time, especially before we knew what it was. We had to remove all the tile (approximately 900 sq ft) and were surprised that there was no cracking in the foundation. There were no signs of expansion joints. We’re replacing with hardwood this time. Again, thanks for the info.

@SalDiBlasi 5 лет назад

Happens more often than you think, lack of movement joints will cause tenting. Can happen after a week or years later. Look up ANSI EJ171.

@davidortega1365 6 лет назад

Sal, love your vids. very informative. I have questions regarding outdoor tile installation regarding this very topic. The video makes sense but I live in Florida in the palm beach area. so we have a lot of humidity. The existing tile that I have was directly installed on concrete with no anti-cracking membrane, and as a result, there are a lot of popped tiles and various cracking throughout. The area is on the front porch under shade but exposed to the elements of heat and humidity. It's roughly 300 sq ft. Of course, I will be removing the existing tile and I believe I should put an anti-cracking membrane like Protecto whisper mat or the Schluter. In regards to expansion and contraction, what do you recommend to ensure a proper installation? Are the parameters different than an indoor install? Finally, does the material whether it be porcelain, ceramic, or stone affect the expansion and contraction differently? Thanks again. Any tips would be appreciated.

@SalDiBlasi 6 лет назад

Outdoor or exposed areas need expansion every 8 to 12 feet in both directions in addition to perimeter movement joints. Tile needs to be rated for outdoors and the substrate should be suitable for tile. I never do outside work because with freeze that it is just too risky.

@haroon420 3 года назад

Shouldn’t the tile uncoupling membrane account for and stop any movement??? I’m assuming the green stuff is an uncoupling membrane.

@SalDiBlasi 3 года назад

Uncoupling protects from movement of the substrate. The house will still expand and contract, the tile will also do that, you need to leave room around the perimeter and in the field to accommodate that. Uncoupling does not stop the movement, it absorbs and neutralizes it. It can't stop the how the entire structure, including the tile, grows and contracts.

@giovannitidona658 2 года назад

Do you ever use the Dilex PVC profiles within the tile field (like BWS)? Curious how you would get things level with long wood planks since those profiles can't accommodate leveling clips. Agree that the edge and transition ones are nice.

@SalDiBlasi 4 года назад

Use silicone if you can get it, can't comment on whether the floor is ok or not, to many variables. Watch this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-74BDTI67S1M.html

For field movement joints with thin tile (1/4") bond breaker tape should be used since backer rods are too thick, right? And how best to set the bond breaker tape down in the joints? Seems tricky. Any tips?

Bond breaker can be anything, even sand. so find something that works and use it.

Hi Sal, what crack membrane did you use on video? I’m thinking of using Schluter Ditra but their system is expensive. I have almost 4,000sf to tile. My concrete floor has several cracks. Is crack membrane recommend for the entire tile area or only need to use it on crack area?

@SalDiBlasi 4 года назад

Best to use it over the whole floor, look at Laticrete StrataMat, it is a bit cheaper.

@gazeozora 3 года назад

Your videos are so helpful, thank you Sal! One question about movement joints at the perimeter of the room, if it is covered by the baseboard do you leave the gap between the wall and the tile empty or should you put grout or silicone beading? I'm starting a slate and porcelain tile multi-room installation this weekend and I feel capable to do it thanks to your videos! Thank you so much for being filming and sharing this information like you do :).

@SalDiBlasi 3 года назад

Just leave the space empty, do not grout that space it will defeat the purpose of leaving it. You can use silicone but really no point to that.

@gazeozora 3 года назад

Sal DiBlasi thank you! Also my tile shop recommended I use the Blanke Permat uncoupling membrane when I told them I don’t want to use a backer board for my install. Do you have any experience or opinion on this product?

@SalDiBlasi 3 года назад

@@gazeozora Blanke Permat isa great product, but I prefer an actual uncoupling membrane as defined in the TCNA Handbook.

@gazeozora 3 года назад

@Sal DiBlasi interesting, I thought it did qualify as an uncoupling membrane (even the sites that refer to TCNA guidelines referred to it as such). What TCNA standard for uncoupling membranes does the permat not meet?

@SalDiBlasi 3 года назад

@@gazeozora TCNA "Uncoupling membranes are defined in the Tile Council of North America (TCNA) Handbook as plastic sheets that have a geometric pattern to create an air space between the tile assembly and the subfloor. ... They were developed to isolate the ceramic tile installation from the subfloor." I would like to know where that air space is. Not saying that it isn't a great product, I just don't see how it qualifies as an uncoupling membrane. I have asked the question several times to the reps and never get a satisfactory answer.

if you don't mind sal an unrelated question ,floor joints continuing up a wall ,I ve been asked to do this with 4 walls of a room and all floor / wall joints lining up ,this to me is major nuisance ,would you have to do the floor first ??

@SalDiBlasi 6 лет назад

Yes do the floor first and follow the layout up the wall, just make sure everything is straight square and true. If you wall is on an angle it is not going to work.

When tiling a floor which is half solid concrete and half of solid timber construction, is it ok to run uncoupling membrane straight over the whole lot? Or would some sort of movement joint need to be applied where the change in substrate occurs? (Even though both substrates are flat and run onto one another).

Hey Sal, do you silicone caulk expansion joints in a shower? TCNA states all corners and the shower base should be caulked. But many tilers experience problems with caulking showers instead of 100% grout. What do you think? Could really use your opinion on this! Thanks!!
