You have a few more problems than some missing tiles. When trenching such as yours, the exposed sides of the old slab should have been drilled and pegged with rebar from one side to the other to help reduce the chance one side will rise or fall different than the other. Was this done in your case? If there is no rebar, the edges of the slab will need to be treated as a cold joint in which case you'd need a grout joint / expansion joint above each side of the trench. Then comes the need to remove more tiles in order to install a crack isolation membrane (or similar) to reduce the chance of in plane movement in the future. This will make for some ugly grout joints. Can I interest you in some nice carpeting?

Fun2B3Here, I canâÂÂt tell you how happy I will be Not to be a floor slave in this area of the house. I have a big Rottweiler and a Maltese so donâÂÂt need any more labor like my lighter tile gives me in living areasâ¦even though I have a big floor steamer. Bbstx and Holly-Kay, thank you!!! Kswl, I hold your complement very highly, thank you! Seagrass, for porcelain that is a good price but you can get ceramic cheaper. I do hope you donâÂÂt think me rude for bringing up price but sometimes I think it good to show things for those of us on a tighter budget who seek to achieve a nicer look. However, so glad you like it! I have been looking at cement floors since just after purchase. It had stinky stained beige carpet that was gross ( and immediately ripped out) and a hideously remodeled moldy bathroom. On another note, now I canâÂÂt wait for the baseboards!

We have 20x20 rectified porcelain tile in main living room that flows into kitchen; in the next few weeks we are installing laminate in the dining room. We have an open floor plan & felt there would be too much tile between the living & dining room so are using the two different materials to break it up. We are also on concrete slab too - our choices are because we have large dogs and durability of tile & laminate.

Are you sure you want to deal with grout lines? And hard floors that are hard on the back and knees?
