I guess if it's good quality cement it should stand up to that treatment. As I mentioned earlier in this thread, there is a cement mix that was used to repair an internal step in our house that the repairman said is more flexible than regular cement. I must try and find what the stuff is called. I imagine it would work really well for this.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
