DRICORE PRO Concrete Repair Polyurethane Injection Expanding Foam (6 Pack) | Moisture Tolerant, Injectable, Expanding, Flows into Small Pits for Sealing Indoor & Outdoor Cracking

DRICORE PRO Concrete Repair arrived packaged well and without damage. My husband followed the directions carefully and was able to seal the cracks in our backyard steps and surrounding patio. He was able to get the solution into small and large cracks, filling the areas and preventing further damage. They concrete repair has held extremely well, even around the railing on our steps. The cracks have stopped spreading and water does not seem to get in. He can't wait to use it on the small cracks in our basement wall. It works well and dries fast, after curing it can be painted.

The concrete foundation on my storage shed split due to an earthquake that we had. The crack is about 2 inches wide and runs about 2 feet long. The rest of the entire foundation is solid and secure. I was looking for something to repair it with where it wouldn't require a major effort. When I found this Dricore Pro concrete repair it looked like a perfect match for my issue and as with everything reading the instructions and prepping properly is the key to a successful DIY job. This is did. I read all of the instructions and watch the manufacturer's videos which helped tremendously.Once I mixed the mixture I injected it into the cracks gently and slowly being sure that I didn't have any air bubbles in it. Once I completed it I used a putty knife to smooth it out and a wire brush to brush the surface to give it texture. Once dried I believe that it is stronger than the concrete around it.One thing I enjoyed was the fact that the material is a yellow color giving me a distinct look in the difference of what I was repairing and the material I was repairing it with. This is a splendid product and I believe it is priced well for what you receive. So far it has maintained it's integrity 100%

I got the polyurethane because it's more versatile than the epoxy, particularly around moisture.It sounds like one of the reviewers simply stuck it in his caulk gun and tried to use it straight. But the polyurethane is still like epoxy in in that it must be mixed (to activate the expanding properties). There's several steps to it. It's not complicated, but it requires prep work and planning. You have to inject it every few inches. Just watch their videos (they're short and to the point), and read the instructions on the tube.I like that this can be used on virtually any concrete job - from foundation repair, to driveway, retaining walls, pools, etc. So many uses. And it's not just a patch, this provides a permanent repair.The epoxy option is what you're supposed to get for structural repairs, but frankly, both formulas are likely stronger than the concrete you're repairing. It's not going to solve any underlying problems (water table, whatever caused the crack), but if it cracks again it will crack somewhere else.There is a 3rd step not included here - after repair, to prevent cracks from spreading, you're supposed to cover it with a carbon fiber mat (again, not included).If you're not covering with carbon fiber mat, you can use the putty knife to smooth out the repair or match the texture of the concrete however you want (and paint over it, etc).My only concern is shelf life. I don't know how long the tubes last on the shelf, or how long they last after it's opened. It's obviously best to save up your jobs, and use an entire tube at a time.I'm not a professional, just a DIYer, but I'm pretty excited about this. At about 30 bucks per 2-pack this is a stellar deal for a permanent repair.

Do Not Buy This Product Junk The Product that comes out of the tube is like water make a big mess

useful for any type of concrete crack repair. can't comment on long term durability but there are plenty of youtube videos, etc that recommend this stuff. application is a breeze and the way it expands is nice for filling deep cracks where you don't even know how far they extend. I highly recommend to get more life out of your driveway, steps, etc.

You do not just stick this in your caulk gun and go to town. First of all, you need a double barrel gun that holds 600ml. Then there is a process to use this involving several steps, a video is on here and you can google for other videos. It works well, we used this to fix a concrete block wall (just freestanding between houses) that had a multitude of cracks and separations in it. We did cover the cracks on the other side so it would not ooze through. We then used it to fill in a fairly large crack on a concrete foundation for a shed, was impressed with the performance here as well. I do wish it came with more nozzles, but you can order extra nozzles if you need to. I am not sure how well it will store once opened though anyway. But the nozzles are a one time use, you cannot clean them out for next time.You are supposed to add a carbon fiber mesh to the outside to prevent further cracking. We did not do this as it would have looked weird on the wall and I would rather just repair whatever other cracks appear.On the tube it has a shelf life of a year.

Excellent value and easy to use. It looks great on our concrete driveway that has settling cracks.
