Foam Backer Rod for Gaps Concrete Crack Filler Joints Foam Gap Fillers Caulk Saver Backing Rod Concrete Filler Rope Joint Filler (1/2 Inch X 33 Feet)

Worked great to redo my joints driveway

Simple product. I was happy with the quality of foam and ease of use.

I put out noodles to catch catfish, and the floats are all made from pool noodles. I thought it would be a good idea to fill the hollow center with backer rod. The theory is that more flotation willhold the line tighter helping set the hooks, and will also tire the fish faster. We shall see....

Worked great to fill in my cracked between the concrete blocks.

For backfilling saw cut concrete it works well. The packaging caused some but not many knots while working. Be sure to unroll before starting.

Consistent diameter and flexibility

the product was rolled up, so it reached me crooked maybe because it is too soft so it was out of shape, i have got a smaller size from a the market that is a lot tougher to maintain shape.

The description accurate
