Great product but not perfect to refill current joint.
This works great and easy to work with. The only issue with using this to replace rotten joint is that the gap between the concrete pads are usually slightly wider. If this product is about 3/16" or 1/4" thick, it will be perfect. It is easier to squeeze it in instead of leaving a gap in between. I end up have to cut a thin strip and squeeze near the top of the concrete gap to complete fill and secure this foam. I little be more work but it works. Let' see if it hold up.

Great product.
I had an idea to use this stuff between stone edging and the lawn. Helps space the grass from the stone a bit, making it easier to cut and edge.

Don't ever buy from this seller, will steal your money if your not happy with item.
Very cheap material, i sent back and only received $1 refund because of shipping fees.

Easy for this DIY!
Easy to work with and does what it is supposed to do. You need to be careful as the 1/2 inch perforation along the top tears off easily.
