Works great. Order a teeny bit smaller than the width of the joint.
The only thing that would make this better would be that it came in CEMENT color!!!!! Great product. My handyman was able to install it easily (put a silicone glue - or whatever it was) down first. This joint filler pushed into the line really well and seems substantial. Looks good - except for the color. Works great. Fits just slightly under the driveway height...not on top.

Great for topping off the gap.
Just put these in on my driveway by garage. The old wood slats had rotted away. My neighbor had pros do theirs for a fortune. I did have to buy self leveling filler for the depth but I put these on top and they’ve set in great. All for a 10th the cost of pros doing it. If I didn’t have to fill in with concrete filler it would take only a few minutes. Of course you need the time to do it. Lucky I don’t have to pay myself.

Get the Tri-Pack to test your fit!
Love the tri pack option. I thought 3/4" was going to be the right fit, however the 1" fits much better. Thank you for making this an option. The item itself is good quality and will look great once installed.

Try many areas
Great way to figure out the size you need, if you have a lot of areas try them all sometimes it varies

The material is soft
I bought the sample kit before purchasing the 1‑inch‑wide 100 ft and 50 ft rolls. The sample kit material is noticeably harder and grips the concrete better. The 100 ft and 50 ft rolls are softer and do not adhere to the concrete as firmly. For a fair comparison, I cut a piece from the 50 ft roll to the same length as the sample kit and compared them side by side.
