Yes
Now you can go out and be a tile ninja and berate people because they have no idea what a control joint is in relation to a tile installation. You can look like a superstar because you can explain to people why their tile looks like a teepee (Read my last post) or why their floor sounded like a gunshot last night. Thats exactly what I've always done. I try to lay out the tile on either side of the control joint and work out from there. If the lay out is critical and I can't do it then the tile is cut at the control joint and filled with a flexible color matching sealant. I've seen tile guys use these tricks in the past that allow them to go over the joint. Control joints can be bridged and moved to a grout joint, although it's better to try and lay the tile out to the joint if possible. It's expansion joints that must be honored thru the tile. __________________. Whether you think you can, or you think you can't, you're probably right.. Control joints also need to be installed above expansion joints in concrete – whether you use a membrane or not. A membrane will allow you to ‘shift’ the control joint in the tile over up to six inches (depending on which membrane you use) but it still needs to be there. If your concrete has a control joint it needs to follow all the way up and through your tile installation. If you don’t install movement joints within your tile work, then expansion and contraction cycles cause stress to tile assemblies that can result in a number of different problems. If the tiles are well bonded, but lack expansion joints, then the problem might manifest as cracking in the tile or grout. An expansion joint is a type of movement joint. Expansion joints continue through the tile setting and the substrate. There are construction/contraction/control movement joints, which are movement joints within the tile work above a control joint in the concrete slab. The control joint can either be saw cut, formed or tooled into This type of cracking can be easily avoided in the tile layer-either by installing the tile on a mortar bed set over a cleavage membrane (method F111 for example), or by installing the tile over a crack isolation membrane using a thinset method.

can you tile over control joints
