Hi, I need some advice to fix a long crack in a slap. The crack was outside the garage and is the border line between the concrete and bricks. Water goes in the crack when it rains and as a result, mortar joints become loose between bricks on the other side or inside of the garage.
I have tried to patch it with some patching compound from Homedepot, but it wouldn't last more than few months, and it cracked again, as can be seen in the pics.
I was wondering if there are other materials that I could try. I have heard of mixing Sand+Concrete Patching Compound+Latex Additive, but I was wondering if it would work due to a fact it's a slap and it could move.
If I have to hire a professional to do it properly, where can I find one? I am from Toronto area.
Thanks in advance!

In my opinion, patches are only as good as the substrate below the patch. I'm afraid your concrete may be towards the end of it's life. I would personally call a pro or continue to patch it yourself to save up the money to replace. I recommend you call a local redi-mix plant to see if they have a list of REPUTABLE contractors to look at it for you. Good luck.

Judging from the RUST on your garage door jamb metal, you've had water there for quite a while. You need new concrete, wide and long enough to replace just the cracks at least. I would address the water problem first, or the water collecting there will ruin (undermine) a new slab too.
Be safe, GBR
