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..
We recommend that you place your control joints no more than 2 times in feet the thickness in inches of the slab. (4â slab 8â joint spacing) These joints must be a minimum of Â¼ the depth of the slab. (1â on 4â slab) Also, it is recommended that you attempt to design panels that are as square as possible. (Avoid exceeding 1.25 times square) For more information see Joints in Concrete Slabs on Grade.
