Akona Epoxy Crack Repair - Injectable Crack Filler for Concrete, Brick, Foundational Cracks and Water Leaks, Clear Liquid Epoxy Resin (6 Ounce, 1)

This filler is so much better than the fillers stocked by the big box retailers. I love the mixing nozzle, and it’s way more fluid than the other fillers so it really flows into the cracks well. Since it is so fluid and soaks into the concrete so well, larger cracks may take more than one application. Tough and durable. The only drawback is that if you don’t or can’t use it all at once, the epoxy will harden in the nozzle rendering it useless for later use. But, fortunately you can order additional nozzles.

too runny and it takes for ever to set so it just leaks out of crack. I used a similar product before which was setting in 5-10 min and that was much easier to use

So far so good. I'm repairing my driveway cracks. I would not recommend for vertical surfaces due to how runny it is. I found it easy to work with. It took longer than 3 1/2 hours to harden. The weather was humid so it took a couple of days.

Filled crack just great was thin crack in stamped patio

Excellent low viscosity epoxy for very narrow horizontal cracks Reviewed in the United States on February 28, 2026 Size: 20 AmpNumber of Items: 1 This is the second time using this product. As indicated it is LIQUID. Not a paste or a viscous material. I wanted very runny, (read not viscous) and it was exactly what I needed. The only complaint I have with this order is that the nozzle was missing. I kept the one from the previous order and reused it. You can clear/clean the inside of the nozzle with automotive brake cleaner and keep it for next time. Works very well in removing uncured epoxy.

Bought this to use on my foundation with a cracked based on description etc. Followed instructions and product never mixed, it remained a clear runny liquid and stopped halfway up the tube. My assumption is that it never mixed as epoxy usually dries quickly. I did not cut into the tube just yet but figured it got hard in the tube. Absolutely wasted monies on this purchase.

Injected the caulking into the crack where I often have water coming in and it hasn’t leaked yet it’s been 6 months and no water

This review is about how they were received. I ordered 4 and 2 of them were missing the nozzle and one had a broken screw top. There is nothing to prevent the nozzle from falling out of the holder that is connected to the tube. I will write another review after I use the product.
