Deck crack

[MollySund]

Hello!
Suggestions for the best possible filler to repair this crack. It's difficult because it "moves" depending on the season?
Is there anything that can be color-matched?

Is it moving? What layers are beneath the tiles?

 

[MollySund]

I perceive that the crack has become wider since the summer. I suppose it is tile cement.

There is no possibility for a repair that will last. Tear off and lay new tiles. Check the waterproofing if you have a room/garage underneath at the same time.

Think it's too small to redo. No room/garage underneath. Open to suggestions on something in terms of filler.

Sorry, but it can't be filled, that is like a cracked glass unfortunately.

The only thing I can imagine that might work is tec7. Available at hardware stores and I believe it comes in brown.

 

[MollySund]

Thanks for the advice! Judging by the instructions, Tec 7 definitely seems worth trying.

Since the stones crack straight through, it's likely the entire slab that's bending, and unless the material you're "repairing" with is extremely plastic, it will probably just detach from the edges or look messy. I'm doubtful that any form of repair can make it look better. Is there a tree nearby that could have a root growing underneath? Something must be causing part of the ground to rise/lower.

Maybe lay a deck mat so the crack can stay as it is?

Since it looks like the crack starts at the fence attachment (also on the other side that is not visible in the picture), I would think that differences in expansion in the metal and the masonry have caused the cracking. In fact, it is claimed that Tec 7 should be plastic. Trees are excluded. It's a bit strange that the crack extends further over the years. One would like to believe that the stresses should have been released?

The crack growing might be frost weathering.
