Attaching closet guide into travertine tile

The pantry in our kitchen has sliding closet doors (just like you normally see in bedrooms). We recently had a contractor replace the kitchen floor tile with travertine tiles. Normally in a bedroom that's easy, just screw the closet door guide into the wood sub-floor, however the kitchen floor base is concrete, not wood. I need to attach the closet door guide to the tile.

Other posts I've seen all apply to drilling a hole through either shower walls into studs or into wood sub-floor under the tile (not into concrete) and then using screws into expansion bolts or similar. I've not found anything that covers my situation.

Drilling through the tile using masonry or diamond tipped drill bits I get, but what about the underlying concrete?

Is there an alternative approach, maybe using glue (what type?)

 

I usually see a small block of wood left attached to the concrete with the tile going around it.

A masonry bit will also go thru concrete, just be sure to lift the bit as needed to remove the dust as you drill.

 

Use a glass bit to drill through the travertine. When you are through that then use a hammer drill to make a pilot hole in the concrete for a plastic anchor.

 

They make an adhesive for attaching carpet tack strips to concrete. I can't say if it would hold well enough to tile but might be worth a try. You could still screw it if it didn't hold.

 

Depending on the hardness of the concrete, you should be able to drill using an ordinary 1/4" masonry bit with no hammer drill. You will need a good drill.
Some anchor packages even include a special bit, which is even better.
