Obviously, we need to figure out how to fix this problem and fill this crack between the garage and driveway. Any tips? Products? Procedure?

It used to have that black spongy strip in it but has since worn away.

DH went to a local company that sells concrete supplies and bought an epoxy product that filled a similar crack between the driveway and garage floor very nicely. I'm sure a general hardware store doesn't sell such a specialized product. I'd ask him exactly what it's called, but he's snoring away in the other room at the moment.

I have purchased concrete patch in a tube similar to caulking tubes and it works very well. Do not be tempted to walk or drive over the patched/filled strip for 8-10 hours or you will find yourself needing to clean the "smear" off the surrounding area. Not that I have done that, of course.

That is your expansion joint! Be careful what you fill it with or it could cause buckling or cracking in other areas.
I haven't looked in recent years but I know there used to be replacement materials for the joint.
The joint will get larger during cold weather and smaller during hot weather...allowing your concrete to expand/contract without damage.
Check with your local concrete place...if they don't have the replacement stuff they should know where to get it or how to fix your problem.

I have fixed many of these types of openings over the years. You will need some foam (backer rod) to fill the gap, or the caulk will continue to go down to China. It is closed foam in a continuous tube coiled form. Measure your widest span of the crack and get this size (just a hair bigger if possible) and wedge it down into the crack. It can be trimmed/shaved smaller with scissors if the crack gets narrower.
I buy foam backer rod from a local concrete supplier at 5-10 cents a foot. And I buy the fill caulk from them too. It has held up far superior to that which I have purchased at the hardware or home stores.

And as mentioned above, the crack needs to clean and dry...then after the caulk goes in, left to cure for a couple of days of dry weather. I would duct tape a couple of flat boards just either side of it, and then you can still drive over the area, till cured.

thanks all for your helpful advice...off to our friendly concrete supplier. Gotta look em up first.

Nance... I was mistaken. I just now asked DH what the product is. He says he DID get it at Home Depot in the dept. where the pre-mixed concrete is stocked. He can't remember the name of it, but it came in a yellow or orange tube. Large tube cost about $18, small one was about $10. Our gap was large, had to be pre-filled with the coiled stuff Conrad mentioned, then with several tubes of the caulk. The product is meant to fill gaps in concrete like these with flexibility. Hopefully, the orange-vested guy at HD can lead you to the product.

Thanks nettiejay for getting back with me. We'll start our search...
