Review: 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.
Review: 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.
