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.

Perfect product.
This product worked perfectly. I ordered the kit of 3 sizes so when I ordered this it was the correct size. Looks great easy to install.

Concrete space filler
So glad I found this product. Much sturdier than the foam backer rod and should last a long time. Very easy to install. Seals the cracks really well, preventing debris and water from getting in between the concrete cracks. Looks good when laid down. Worth the price and highly recommend. As stated, make sure to measure your crack widths, I had to order 2 different sizes for different places.

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.

A must have prior to ordering to fix expansion joints
Saves time and money- filling those cracks in between driveway lines( expansion joints)- not a fun task. These allow you to test the size. Then order the correct size. Keeping water from under your slab is crucial. These help with the task… a lot. I initially ordered the wrong size. The boxes these rubber strips come in are big and heavy ( not these but once u order the correct size and length.) they are in long circles. This allows you to get the correct size easily.
