I recently learned about this product while exploring how to fill in concrete joints. The product is reasonably priced, durable and easy to use. I plan on filling in more joints as I water proof and repair concrete joints for safety and a great look when complete. Thanks for this product design.

Good product that has a variety of different uses. My main use for it is when I have to caulk a rather large gap. I'll first fill the gap with backer rod, then caulk. I get better much results that way. It gives the caulk something to grab to, and the caulk won't shrink too much.

Filled a gap between the front door threshold and the floor. Worked perfectly! Easy to install and very effective at blocking the draft.

Perfect Fit
I used this as a gap filler between my driveway and garage floor to fill expansion gap between the two. Once in place I used a self leveling compound I bought also at HD to level off the gap to 1/2” from driveway and garage floor top edges . Worked perfectly, beautiful job. Just remember not to twist the rod as it will show the ripples on the surface of the leveling caulking you use.
