Concrete Joint & Crack Fill, 1/2 D, 125ft.

Great solution!. Time will tell on the longevity of the product. Easy to install, using sand as a base. A little pricey, but much better than wood or plastic expansion joint solutions. Those are solutions that fit only the most perfect cuts in your concrete, while CrackStix forms a water tight seal.

So I had a slightly different use case than a crack in a driveway or sidewalk. I have a long sidewalk with a decorative block side wall that runs through my citrus and olive grove, and most all my gutters and yard drains end up flowing down this sidewalk. The inside corner where the sidewalk and half wall meet had cracked and separated slightly along most of its length, which left all the water draining under the side wall and into the soil where it formed an underground river through the grove, right past some olive trees. I needed to seal the inside corner to keep the water flowing down the sidewalk to the end where it dumps off into the creek.I got this Crackstix, cleaned the area and laid this out. Used the recommended torch with a 20lb propane tank. The Crackstix melted easily and flowed like a viscous liquid into all the cracks. In some cases I used a putty knife to smear the melted stuff up the side wall a bit then reheated it to seal and smooth it all out. In some areas the gap was large and the melted Crackstix seemed to flow down into the gap too much, so I doubled up and ran a second line and melted that over top of the first batch. In the end, visually I got all the area (~60 linear feet) sealed up nicely.The proof was in the big rain today and the seal job worked perfectly. All the water flowed all the way down the sidewalk past the grove and down into the creek. Not sure how long this repair will last, but for now its a water tight perfect seal. Kinda fun to melt it all up and watch it flow into every nook and cranny making a good tight seal.

I was looking for something to fill the spaces between the concrete breaks in my sidewalk path. They had gotten so deep that part of the sidewalk had sunk and I had to have it "lifted" earlier this year. This filler was perfect for filling the cracks and will hopefully prevent any future problems. Very easy to use. I ordered the propane and torch that were recommended with it.

Easy to install. Needed some high temperature heat to form in place.

Really fills cracks well. Takes some practice to get it to melt without burning. Even burnt, it works fine (kind of like toasting marshmallows). Buy a torchhead that works upside down. Big cracks take 2 strips or more to fill. Deep areas need backfilled before application. I have been using construction sand. Amazon keeps showing filler strips-put a torch near foam and see what happens. You could fill with expansion filler from HD that comes in 6,8 or 10 foot pieces. If you try to fill too deep or wide you will end up spending a fortune on this material. It will work.

Works as advertised. I had to have something to fill in the 1" deep x 1" wide crack control joints in my newly built garage floor to keep trash from packing into the joints. I had about 40 linear feet to fill in so the 125' bucket was waaay overkill, had a lot left over. Should have just purchased the 1/4" bucket only and maybe layed down three 1/4" sticks. The joints where very deep, so the 1/2" didn't quite fill the gap all the way. Another 1/2" stick would have just overfilled the joint, I tried to just melt a stick on top ofthe already melted 1/2" but was very hard to keep from over heating it and burning. It would have worked much better if I had melted in a 1/4" stick and then a 1/2" stick on top of that or just used three 1/4" sticks. In the end, I ended up with about a 1/8" to 3/16" drop from top of concrete to the surface of the melted stick. Melted well, layed down flat, looks good and I'm happy with the results!

In a hot environment, it will get soft. I would not spend the money on this again.

I didn’t find that this product was very easy to install, the plastic that is around the rope seems to interfere with it sticking to the sides of the joint or crack. Adding more heat tends to leave the stuff with brownish black marks, the only way I found to make it usable was to hold the rope about an inch away from the crack and melt the plastic off the underside before pushing it into the joint then melt the top, took a lot longer to do the job than by using the pourable stuff but it does stick like crazy
