good stuff
Would RecommendI utilize this on my concrete driveway where it had cracked ( 1" x3") . This helped me stretch out the filler and if the concrete shift any the foam will help out
Versatility of Backer Rod
Would RecommendNeeded "backer rod" (foam rope) to fill structural gap ~ in my case to minimize drafts/cold air. Various diameters and lengths available. In my case, the 3/8" was perfect and one gap needed about half the diameter - surprisingly enough it was easy to split!
