This is it!
This is an amazing kit to stop water coming in through cracks in a basement concrete wall! I fixed a crack 14 years ago with this kit and there is no sign of water in the basement to this day. The repair is done completely from the inside so no digging outside. Installs fast and easy. The expanding foam is so powerful that it pushes completely through the crack to the outside of the basement wall. If you have a crack in a basement concrete wall and water is coming in and the crack is hairline to 3/16” (or probably much bigger) this kit is for you. No need read further. You’ve found the solution. I’ve bought 3 kits for 3 different cracks.

Great value
Saved me thousands of dollars! I had a leak in my basement and hired a contractor to repair water damage. He Recomended this two part epoxy kit as he has used it with success in other situations. As the crack was inaccessible outside due to a 1,000 sqft deck needing to be ripped out to get to the affected area I gave this a try. So far so good, as we have had a few heavy rains and in both areas we had no problems with leaks anymore. I covered both cracks with carbon fiber “tape” and epoxy as an added layer of protection as the basement will be finished eventually. Only thing I can advise is take your time on the prep, align the ports properly and follow the directions and it will work. Saved thousands by doing it myself.

Great quality repair kit for non-corner cracks
Very good quality crack repair kit. Enough for more than 10’ of crack. Frankly, if the crack sealant is out, you can use any way to seal the crack from outside and then use the foam to seal it. The only reason why I gave it 4 stars is because its very difficult to use the corner injectors. Its not easy to stick the corner injectors on corner cracks on concrete. I have used this product at least twice in the last 3 years and it seems they haven’t improved the corner injector design.

Rethane Cracks filler works
Product and instruction are spot on. I didnt use the kit until 5 months after I purchased, which may have created my only issue. The epoxy tunes were so firm, I had to cut the tunes open to extract the two-part epoxy. It was messy and I broke most of the wood applicators/mixers. Maybe that's why they give you so many. I had one left. The other supplies, vinyl gloves, plastic ports, extension tube are all good quality. The caulk gun was OK. When I applied a decent amount of pressure, it slipped. I ended up using my old caulk gun. The urethane foam worked well. I couldn't quite duplicate the fill process from the video...where the urethane spills out of the next port above. However, I could see the foam in the next port, so I would then proceed. The foam expands 2 or 3 times the liquid volume. The injection times per port were also accurate. The Thin cracks easily took 5 minutes to spread. Good product. I would recommend to anyone for their basement cracks. Contractor price was $500 per Crack, so I saved $350. Good luck. Watch the video.

I have to share the amazing result of this product
I'm not much of a product reviewer but I have to share the amazing result of this product. We are the new owners or a 70 year old suburban ranch with a poured concrete basement. Past owners have added structural braces to address the wall folding in from hydraulic pressure over the years. Our current circumstances are water in the basement with a heavy rain. Searching online I found recommendations for Hydra Stop so we gave it a try. Past unsuccessful repairs were excavated and following the detailed instructions we installed the first kit. Next rain the original leaks were addressed but they moved farther down the horizontal crack so I ordered another kit. This crack was much smaller and we the experience of the first kit we were able to extend the repair. Next rain and our basement is dry! We also cleaned the rain gutters and plan to regrade the yard to keep water away from the foundation but I am impressed that Hydra Stop was effective without this other corrective work. Installation can be messy so use all of the PPE and plastic drop cloth provided in the kit. Don't freak out if the foam you inject come out of spaces you didn't expect. Just let it cure and then scrape off with a putty knife. The attached photo are a real world installation as compared to the product demo videos online. Bottom line is this is a very effective product to address ground water entering through foundation cracks even when installed by DIY'ers. I would recommend to a friend.

Epoxy is Garbage
Do not buy! Deceptive . The epoxy portion of the product is absolute garbage. Conveniently all of the expiration dates and product mfg. codes were smudged and unreadable on both the epoxy and poly foam crack filler. At best poor printing machine at worst it’s fraudulent. This is my second purchase of this this product. First kit I ordered 1 year ago. The epoxy came in two small cans of part an and part b. Much easier to mix than the epoxy in the caulk tubes. The epoxy in the caulk tubes is so hard to get out of the tube and it does not come out in even amounts. I did not even use the caulk gun that was provided. I used a very nice, high leverage tajima caulk gun. Even with the fancy caulk gun it’s was nearly impossible to get the epoxy out. I put the epoxy tubes in warm water and had slightly better results but still had uneven flow from the the two parts. The warm epoxy also sets up quicker. Also the amount of epoxy is not nearly enough for a 2 inch wide strip that is 1/8-1/4 inch(around the ports) high build thickness. I used fiberglass mesh bedded into the epoxy to provide a bit more strength because I was not able to apply the epoxy in the thickness detailed in the instructions. Utter waste of money and more importantly a waste of time. Do yourself a favor and find the other brand of expanding poly crack filler and buy the ports and then buy pC-11 two part marine epoxy. Much cheaper and way easier to use. All this coming from professional carpenter with 30 years in the trades. I wish I could give this product 0 stars. That said the kit I got last year with the two cans of epoxy worked pretty well and took care of the first of many hairline cracks in my foundation. To the company that puts out this product, GO BACK TO THE 2 CANS OF EPOXY!!!

An absolute must-have if you live in wet environments...
An absolute must-have if you live in wet environments and have cracks in basement walls. I live in Iowa and this has saved my basement many times over. I bought a house 3 years ago that was a 2003 build and to date have sealed about 55-60' of vertical wall cracks. This has taken place over the last 2.5 years. This stuff, without a doubt, works. You just have to do YOUR part of the project correctly and the product will do it's part. Every single inch of crack that I've repaired with this product has stayed water-tight through HEAVY rains and standing ground water. 1) Read the directions. 2) Watch the video 3) Read the directions again 4) Watch the video again 5)Have some mechanical/construction sense about yourself or have a friend who does, help you 6) Read the directions again. Yes, I'm repeating myself. Take your time and allow the epoxy to cure. Apply the epoxy correctly. Work in small batches. Overlap. Heating the resin tubes prior to injection, in hot water (hot from the tap, no hotter) is a good tip as mentioned by another user. That's smart. Warmer liquids flow easier/better. Wear old clothes that you don't care about ruining because if you are not diligent, you will end up with epoxy or resin on your clothes, and guess what, it's not going to wash out. Put down plenty of floor covering. Plan on anything this resin comes in contact with having a permanent resin stain. I'm saying that so you will know to again use due diligence in covering whatever you're not OK with staining. It smells, some say awful, some are nauseated by this smell. Move as much air as you can in your project area. This will help dissipate that smell and shorten cure times on the epoxy. After the project is done, plan on that smell lingering for a day or so, but it does go away and your area will go back to smelling like it did before. Once cured, there is no product smell. Again, I have runs that are 2.5 years old that produce no smell and are water-tight.

Bone Dry, Saved $10,000+
Finally, no more water or moisture after 2 years of slow water leak into basement. This kit did the job and saved me over $10k of expenses. Starting at least a couple years ago, small amounts of water would leak into a section of my finished basement during moderate to heavy rains. Not much water, but enough to leave a puddle or more, and require a wet/dry vac and floor fan each time. My house was built in 1999; poured concrete basement walls. Adding dirt grading outside the house did almost nothing to help. Diverting the downspouts 10 feet away from the house helped with moderate rains. But any heavy rain or a plugged up gutter would instantly bring a big puddle of water inside. I was told by multiple contractors that deep excavation of the exterior ground was required to find the crack and seal it. One estimate was at least $10,000 just for the initial excavation! I found this kit and the video online. I had a hard time believing it. But $150 was worth a shot. I opened up the dry wall expecting to maybe find a 6” crack. No! There was a crack; and it extended from the floor to the top of the concrete wall! Almost 10 feet! I followed the video instructions. The whole process, in total, took less that 2 hours of my time. The kit contains literally EVERYTHING you need, except for tap water! 😊 It even included the wire brush for cleaning the surface. Mix small amounts of the epoxy at a time; it starts hardening with 5 or so minutes. Make sure you are liberal with the application of the epoxy. This is to make sure there are no cracks/leakage points when injecting the resin. It worked! My basement has remained bone dry. Even with the downspouts no longer diverted and several long lasting torrential downpours of rain. I even soaked the exterior at the wall for 20-30 minutes with a garden hose. No exterior excavation or other corrections required. This interior-only solution work!
