## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great.  Order a teeny bit smaller than the width of the joint.
*by D***M on July 7, 2025*

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.

### ⭐⭐⭐⭐⭐ Concrete space filler
*by Y***E on August 30, 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.

### ⭐⭐⭐⭐⭐ worked great for my purpose.
*by L***K on August 5, 2025*

I got this to fill in a gap between my dining room and living room. My dogs had ruined the little strip that was there and I had the metal strip left. I trimmed down/off the bottom row of things. It fit great. Now when i use my roller stool, the wheels don't get stuck in the track, or get messed up. I got it to snap into the original track. Please being able to buy the trial pack of the 3 different sizes worked will so I was able to get just what I required.
