Review: 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.
Review: 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.

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.

### ⭐⭐⭐⭐⭐ Review
*by Y***E on 30 August 2025*

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.
