1" Closed Cell Backer Rod/Crack Filler (25 ft)

Works as stated. Used to plug concrete expansion joints

The tubing was used to increase effectiveness of a roll up garage door bottom seal, that had flattened from years of use. This fix was recommended by a professional garage door installer. The original seal tubing had flattened, causing areas of rain leakage. The Backer rod tubing was pushed through the flattened bottom seal to "reinflate" the tubing enough to form an effective water barrier. The material was soft and flexible enough to form a tight seal against the garage door slab.Completely unrelated to the product quality itself, was difficulty encountered when working thetubing through the original seal tube. It must be noted that the use of this product was not for an approved application, so the product was never at fault. This product can be used for the application for which it was purchased, but note that installation difficulty may be encountered. This product is best used for its intended applications.

I purchased the 1 inch backer rod and it was exactly what I needed. It also arrived before the delivery date!

I ordered this product because the 1” size was what I wanted for a project I was working on. I also ordered from this seller because they said it was sold in 25’ lengths. I needed about 22’ continuous for my project and other sellers listed 10’ and 20’ lengths so I ordered this product. When I got almost thru the project I found there was only 20’ otherwise it was just what I wanted.

Did a perfect job!

This backer rod is part of my sidewalk expansion joint replacement. Pulled the old, rotting wood, filled the crevice with paver sand to 1.5 inches from the top. Tamped it down and leveled with a piece of 1.5 inch wood. Laid this backer rod on top of the sand, which fit tightly and sealed against the cement. The backer rod also reduces the amount of sealant caulk needed. Ideal depth is about 1/2 inch of this self leveling sealant. End result is shown.The local blue and orange stores did not carry the 1 inch backer rod, but this shipped quickly at a very reasonable cost. It is the density needed for this job and cuts easily with ordinary scissors. Don’t settle for the more common 3/4 inch, which may not yield a tight seal essential for SSL caulk.Highly recommended

These 25 ft rolls are dirt cheap and fill a lot of volume. Bigger and cheaper than any backer rod I could find at home depot.I used together with Sikaflex self levelling sealant which is great stuff, but really expensive per tube. This helps you minimize your usage of it, and to ensure the rod doesn't float up in a wider crack. The backer rod helped keep my project cost down by about half of what a sealant only solution would have been, and probably ~$15 less than if I used more of the small rod options available at HD. The results came out beautifully.
