Rated 4.0 out of 5.0 by DIYOKC Easy to use
Purchased this to replace and fill expansion joints around the pool deck. Some tips- if your expansion joints are really deep, pack them with sand first. You won't need to use so many layers of Crack Stix and thus, won't have to buy as much. Also, purcahse the propane torch with the hose. A standard propane torch
Will not work. Last tip, it takes some practice to make the filler look nice, so start somewhere less noticable. By the second or third application we were very satisified with our efforts.

Takes a bit of skill so start learning in the least seen area. The hotter the flame the better it works.

Rated 4.0 out of 5.0 by How277 Worked better than caulking
Used caulking first to seal cracks in the concrete around house foundation to stop water intrusion. It peeled away by end of winter. I used a heat gun instead of a propane torch and it did a great job. So far with the little bit of rain we've had it's doing the job. I'll see how it does over the winter.

Rated 5.0 out of 5.0 by John Crack-Stix fill seams in large concrete driveway
I'm strictly a home owner/DIY type. Power washed my driveway a couple years ago and washed out the deteriorated spacers in the cracks and needed to find something to fill them back in. These were fairly deep and some quite wide up to an inch at the top. After cleaning and backfilling with dry sand to the desired depth I installed the crack-stix and using a large torch melted it in. This takes much longer than I had anticipated but most DIY projects seem to. Maybe I'm just a bit more cautious than most. This product takes a lot of heat to melt thoroughly so definitely use a big torch like a weed burner otherwise the stooping will destroy your back. As the product melts you will notice it does not flow readily. It just melts and oozes. Be sure to follow the directions as to how much to use to fill the gap and in addition heat the concrete of the crack enough for the material to kind of melt into the pores. The finish is amazing. Best of all, the wife is pleased with the results. This was a very satisfying project.

As easy as it says results without the mess of caulking tubes.

Product is impossible to have uniformly distributed unless crack is uniform. It is notself-leveling even across the with of the crack. The gray is very difficult to melt without discoloration. Chaulking is much better option.

Rated 5.0 out of 5.0 by DMS Fills and seals great
The joint I need to fill was 1" wide, 1.5" deep and 44' long. I cleaned it out. Then, I filled about 1/2 with paver base. Then I filled a little more with paver leveling sand. I laid crack stix in side by side. I put additional short pieces where there was more than 1" wide (like a chipped edge). I followed instructions just as published. It worked perfectly. Looks great. And it is SEALED, not just filled !!

Rated 5.0 out of 5.0 by BillH Great solution to a common driveway problem
I suspect most homeowners aren't aware of the undetected and ongoing rainwater damage to their concrete driveway until after a couple years when the individual slabs begin to raise and settle--creating unsightly and annoying bumps.. This results from the inevitable development of cracks and/or wearing away of fiberous expansion-joint material--all of which allows water to enter and tunnel away and mound the essential dirt, sand or gravel underlayment. I've tried various fixes over the years: tar, putty, and calking--all of which have drawbacks (color, eventual cracking, expense).This is the first product I've found which appears to really address the problem. I'll still need a year or so to confirm, but the prospects look encouraging.
Comments on installation: after prepping the gaps by cleaning out with screw driver and filling with sand to an appropriate, shallow depth, I was ready to lay in the rope-like crack filler. It takes a lot of heat to melt the crack filler material and adjacent mass of concrete, so a robust blow torch is essential. HD sells a good walk-along torch (approx. $35) which hooks up to a gas grill type propane tank. I tied mine with bungy cord to a 2-wheel hand cart which towed along conveniently.
This crack filler rope is very flexible and lays in nicely. In one wide gap situation I did a double layer (which instructions recommend against); it melted, filled the joint and bonded completely. In one situation I had to fill a gap alongside a foundation wall several inches away from wood framing, so I positioned several concrete blocks to serve as a heat shield for the wood. Note: building unscarred and still standing.
Overall, I am pleased and encouraged with this product. It installs easily, is flexible and bonds well with the concrete, matches the color, and can be stretched or even doubled up to fill a broad width range of difficult cracks. I haven't seen any other products on the market that meet all this criteria.
