concrete crack filler

[benny27]

I have some good sized cracks in my drive way. About 1 inch wide at the widest.
I am have seen cracks around town that are filled with what looks like caulk. What is that stuff called? I bought this pourable Concrete Crack Filler http://www.menards.com/main/buildin.../p-1768883-c-5650.htm?tid=1473182559254273580 but when it dried and was not vary flexible and did not stick to the concrete that good.
So what should I get to fill the cracks with?

1" is really wide.

Did the subgrade erode in the areas where the sections have settled?
If the slab is sound and not moving I would vgroove them with a quickcut, and fill them with top & bond, make sure you moisten the area. Blow out the crack with compressed air prior to moistening it

Is there any height difference?

use paver polymeric sand

If you are looking for something flexible I used Sikaflex self leveling. It comes in a caulk tube and I got it at Home Depot. It worked great for me.

There is not much of a height difference. It is a 2 car wide drive and the crack goes down about in the middle.

I used SHERWIN WILLIAMS POLYUREA JOINT FILLER

It worked great on most of the cracks in my driveway. I used a chisel and hammer to open them up to at least 3/8", then blew them out with compressed air.

The polyurea stays semi-flexible and levels out nicely.

A terrific Commercial grade 2 part polyurea crack filler is Metzger and Mcquire RS-88. Email us if need to purchase as we don't sell it on our website, but can get it for you through our Installation Division.

I agree with this option. Grouting them makes more sense than a polymer which will never look like it belongs on a clean concrete drive.

Use backer Rod. I haven't seen wider than 3/4" at HD. Gator dust should make quick work but how deep is the crack at its deepest?
