Hey Cookieman,

Yah I have had the same problem concrete driveways. Most crack fillers aren't made to stand that kind of traffic and weather change. What I used for small cracks is a construction sealant. I never had cracks bigger than a quarter inch, but for the normal small cracks it worked great. I used Sika brand because it is flexible and matches the color of the concrete drive way. I wouldn't use anything meant for a asphalt driveway. Even though it might work it wont look pretty.-Gregg

As Gregg said, the Sika products are very good for this issue. If the cracks are deep and/or wide, use a backer rod to shove in the crack to limit the anount of material you have to use. The backer rod comes in widths of 1/4" -3/4" so you can find what you need.
