6-10' DIY Waterproof Epoxy Concrete Foundation Crack Repair Kit for Basement Walls - Professional-Grade Solution with 12,000 PSI Strength, Fast Gel Time, Seals Leaks, Easy-to-Use

I have used this to fix cracks in my basement wall. Works very well.

This product is amazing and performs as promised. I recently used it to repair a leaking crack in one of my concrete basement walls with no issues. Two days after repair, the product proved itself as we had several major storms pass through our area in the span of a week. It was simple to use and everything that you need to complete the task is included. Twelve years ago I used this same product on another wall and it still holds to this day. I would certainly buy this product again and have recommended it to my friends.

I used this years ago to seal up cracks in my foundation. Make 100% certain you have everything laid out. Understand the instructions. And even do a quick run through of how you will insert plugs quickly. So slow, dont try to rapidly force the liquid in really fast. The plugs do snap off after a day of curing. The only downside is that some will leak out the back of the wall if you are sealing cracks in the foundation above ground. It also has an odor(2 part epoxy) Ventilation may be required for some.

Did not adhere properly

I paid someone to use this in my basement crack in fall of 2025. He’d had experience using this and doing this kind of stuff. So far it’s working great. No further water leakage

The product did not fill cracks as described when following the directions. Also the packaging varied from the Amazon description. Specifically the epoxy came in jars rather than epoxy tubes which created a big mess compared to an easy to use tube. In my case I was not able to get very good adhesion while following the directions exactly. Maybe it was the material my walls were made from however it should probably be stated in the description.

The frustration is on the fact that the nozzle is a push-in instead of a threaded and by that reason slippage and unnecessary waste happens. This product is overpriced. You can remove the instructions cd and provide link to a video, spatulas, gloves, wire brush and even safety glasses we can buy our own. There should be an option to buy the items separately because now than I'm out of the resin you're forcing me to the whole kit! I will update this review in a few months.

Extremely happy with the results and the epoxy adheres extremely well even to clean freshly painted surfaces. This is a repair I will never have to worry about again for the rest of my life. I was skeptical with how well it would work on a hairline crack but it flowed just really really slowly. The caulking gun is only good for the epoxy paste I would recommend using a better caulking gun for the actual a-tech 212 epoxy. If you have a small crack go slowly and expect it to take longer.
