uPlug DIY Foundation Crack Repair Kit (5-FT) – Foam Filler & Injection Sealant for Concrete Walls

After researching the various kits being sold on Amazon, I chose this one due to the price. Other kits provide more tools but I already had a caulk gun, gloves, and wire brush. I followed the directions which were very straight forward. Seems to have filled the entire crack. The foam expanded to the outside so I'm pretty confident it is sealed all the way through. I filled 3 4-5 foot cracks in my foundation and still had liquid left. However, I ran out of the paste and ports. Tried to seal it up to save it but it hardened up quickly after sealing.Very DIY friendly in my opinion. Saved a ton by doing it myself.Ordered another kit because I am extremely happy with the results and the insanely fast shipping.Update May 2025: After having many heavy rains everything is still solid. No leaks at all.

FIrst, wear your gloves. Both the epoxy and urethane are pretty nasty, and they will get on your hands.Second, mix the epoxy in small batches and have everything laid out where you need it. This epoxy cures very fast.Pro's-This stuff just works. It is going to find its way into every nook and cranny in your wall.-There seems to be plenty to do a 5 or 6 foot crack. There is more than enough epoxy, and there seems to be adequate urethane for a moderate crack.Cons-The eopxy is WAY too fast. I have experience with Marine Tex, JB Weld, Bondo, various fiberglass products and various epoxy products from the hardware store, so this is not my first rodeo. I have never seen epoxy that sets up this fast (my house was 75 degrees F). I didn't time it, but I probably had no more than 60 seconds to get it on the wall before it was too hard to work. This led to sloppy, less-than-ideal work. I tried to reduce the amount of hardener in one batch. That didn't really help, and I didn't want to stray too much from the instructions. I counted, and it took me 14 little batches to more or less get done.-There was only one set of gloves in the box. Get yourself more gloves, and use them throughout the process.-There were 7 'ports' in the box. I might have wanted 2 or 3 more.Overall, I would use it again, but I might go get some other epoxy from the harware store. The epoxy is the reason for 3 stars.

Had a 5ft vertical foundation crack I wanted to fill before the walls got spray foamed and this was really easy to do. Just need to be patient! Put down some cardboard, use one stick for A and the other for B then another for mixing together and do small amounts at a time because it cures fast. Do NOT mix the mixing sticks in the Part A and B. Once that part is done just set a timer for each port...use low pressure on the caulk gun and it takes a about 5-7 mins to start seeing eutherene come out of the next port. Worked like a charm.

This crack repair kit works, the expanding foam is perfect and flows into the cracks well. The epoxy is not so perfect, this stuff hardens in minutes. You have very little time to spread what you mix together. If I purchased this kit again, I would order some extra epoxy. I had some pin hole leaks that the foam expanded out of. So would I buy it again yes if I purchased extra epoxy to do a better finish job. Another plus is there was no harsh smell. And I am sure the way this stuff expanded I have no chance of a leak!

This stuff is great! Before I was calling basement repair contractors and paying thousands for them to come do the same thing. I filled a crack on my garage foundation so vertical wall with a horizontal crack. As other reviews read directions carefully, take your time. Side note maybe buy extra wooden mixing sticks as some you can’t use the further you get into the project. Keep some extra cardboard handy so you can put it under if there are any leaks. I’ll be buying more if any other cracks pop up

Fixed cracks on 2 spot.Worked out well

The epoxy was not smooth. it was not easy to spread and set up too fast.the directions had a very fine print and not easy to read.

I did end up with twice the amount of expanding foam and about 1/2 the amount of epoxy i ended up needing. I bought some extra epoxy and thought I finished the job, maybe even over did but I had leakage or blow outs under a few of the injection ports. A few tips: wear rubber gloves and get a few extra pairs; i also needed a few plastic butter knives. The epoxy dries very fast. If I had to do it again, I'd start with a small amount and just do the bottoms of the ports for the 1st application. This way you'll get a feel of how much to mix at a time and it will also allow u to take a break and inspect that is good and covered. The bottoms were the trouble area for me. I was fortunate that the injection foam ran out with about 3 ports to go, as it ended up making it the rest of the way and even barely out of the top of the wall due to the expansion. So stop a few holes short. After I finished the injection I waited a few days to remove all the junk with a chisel, I was surprised how easy it was. I had a pretty big pool on the floor at the end, so make sure u have plastic taped down. I also ran tape along each side of the crack before applying the epoxy, thick duct tape. I think having a straight hard edge made removing it easier. Lastly I cleaned up all the leftover junk, retaped the sides and spray painted over the area. It hasn't leaked again yet and we've had some pretty heavy rain. Before the job I'd get about a half gallon after every rain. My walls are 8' and if I didn't have the blow outs, I think I could've easily filled a 12' crack. So basically get some good 2 part epoxy and 1 kit will be enough for 2 cracks; if you really do a good job coating the bottoms.
